3 Quick Steps to Adjust a Blow Off Valve?

November 19, 2021 No Comments

Video: How to Adjust A BOV

Why Would Anyone Want to Adjust Their BOV?

If you have ever wondered why someone would go through the trouble of adjusting a blow off valve, wonder no more! There are several reasons someone might want to adjust their BOV, and we will explore a few here.

One reason to adjust a BOV is to change the point at which it opens. Depending on how your BOV is adjusted, it can open earlier or later in the rev range. This can be beneficial if your car struggles to make power at high RPMs, as opening the BOV earlier can help relieve some pressure build-ups.

Another reason to adjust a BOV is to change the sound it makes. Some people like the loud “whoosh” sound that a BOV makes when it opens, while others find it highly annoying. Adjusting the BOV can help you find a happy medium between the extremes.

Finally, adjusting a BOV can also help with reliability. If your BOV is set too low, it can cause your engine to stall when you come off the throttle. Conversely, if it is set too high, it can cause your car to lurch forward when you get back on the gas. Adjusting the BOV to find the perfect setting can help keep your car running smoothly and prevent unwanted surprises.

So there you have it! These are just a few reasons someone might want to adjust their BOV. Whether you’re looking to improve performance, change the sound, or ensure reliability, adjusting your BOV is a great way to do it.

Before You Adjust A Blow Off Valve

If you have ever wondered how to fine-tune the performance of your valve, check out the video above. Each Blow-off Valve (BOV) or Bypass Valve (BPV) needs to be adjusted to suit the vehicle it is mounted.

Vee Ports, Supersonics and Dual Ports

The aim of the adjustment on Vee Ports, Supersonics and Dual Ports is to make sure that the piston is hard closed at idle and that the piston closes fast enough to minimise backfiring and not stall the engine.

Plumb Back

Equipped with a spring, Plumb Back BOVs are designed to keep the piston open at engine idle. Hence, the cap can be left in the middle position.

Adjusting BOV

How to adjust a BOV?

  1. To Adjust the BOV, rotate the cap, this increases the spring force on the piston,
  2. Rotate the cap clockwise in the direction of hard as marked on the top of the lid.
  3. To decrease the spring force on the piston. Rotate the cap anti-clockwise in the direction of soft as marked on the top of the lid.
How to adjust a blow-off valve

Quick and Easy Steps When Adjusting a BOV or BPV

  1. Start with the BOV cap at the top soft position. Note: The edge of the cap should completely cover the indicator O-Ring.
  2. With the engine at idle, the exhaust port should be closed off by the piston, and therefore the piston should be hard against the seat and not floating or moving.
  3. Free rev the engine and back off quickly. However, the engine should return to average idle speed if the engine drops below idle or stalls. Go ahead and Increase the spring tension by one turn.
  4. Repeat this process until the engine free revs and returns to average idle speed.
  5. Test drive the car and ensure that the engine has minimal backfiring and no stalling when decelerating or changing gears. If you notice backfiring is excessive or stalling, check all connections made during the installation. Otherwise, increase the spring tension.

TECH TIP: BOV TROUBLESHOOTING

If you have installed a vent-to-atmosphere BOV and your engine has started to dip below normal idle and stalling, follow these steps:

BOV Troubleshooting Steps

  1. Firstly, check that the BOV is closed at idle if the BOV is not completed at idle. There’s a good chance the spring tension may need to be increased, or the BOV might need a heavy-duty spring.
  2. Next, check the vacuum hose for splits, cracks, loose connection, kinking or any obstruction. It would be best to replace the old or tired hose’s, and it is also essential to know these hoses may collapse under a vacuum causing an obstruction.
  3. Lastly, with the engine running, remove the vacuum/pressure hose from the nipple in the cap of the BOV. You should hear a loud hissing sound. The engine should idle poorly. Double-check by covering the end of the hose with your finger. If this does not occur, the hose could be blocked or crimped. Thoroughly check the hose and replace it if necessary.
BOV Troubleshooting

If the stalling dipping idle is still occurring follow these steps:

  1. First, ensure that the vacuum/pressure source is not shared and that the vacuum source is directly from the inlet manifold.
  2. Next, check the seal between the adapter and the BOV – ensure that there is no gap between the BOV base and the weld flange.
  3. Lastly, check the join between the adapter and the intercooler pipe for leaking.

5 ‘Facts’ About External Wastegates That Are Wrong

November 10, 2021 No Comments
Turbosmart Electronic External Wastegates

External Wastegates

External Wastegates are one of the most commonly misunderstood pieces of the turbocharging puzzle. Plus, these devices regulate boost by allowing exhaust gasses to bypass the turbocharger’s turbine. Therefore, making sure the compressor does not spin too quickly and produce too much boost.

However, many myths and misconceptions are floating around, so we picked five of our favourites that we have heard and let our engineers bust the myths.

1. You don’t need an external wastegate.

Well, if you aim to destroy your turbo or blow up your engine, then yes, you don’t need a wastegate! While, in theory, you could run a turbo system without a wastegate by carefully choosing a turbo that will only reach its maximum turbine speed and desired boost pressure at the engine’s max RPM, it’s not practical in the real world.

2. The more powerful the engine, the bigger wastegate I need.

False! A wastegate is possibly the only component in your whole engine package that can be made smaller as you increase your boost/horsepower output – in certain circumstances. A wastegate drives exhaust gasses away from the turbocharger to regulate turbine speeds and boost pressure. 

Selecting the correct wastegate size depends on the amount of exhaust to be bypassed, the desired boost pressure, and the amount of exhaust gas the turbo requires to reach that boost pressure. Also, an engine that produces a lot of exhaust gas but runs low boost levels will require lots of exhaust to be diverted away by the wastegate, requiring a bigger wastegate. Higher boost levels will need less exhaust to be diverted away from the turbine, so smaller wastegate.

3. External Wastegates don’t operate in high temperatures.

It’s common to find External wastegates mounted at the hottest part of the exhaust, and it’s where all the exhaust gases meet, creating extra heat.

Mounting a wastegate permanently, somewhere it can cool off, rather than being choked with hot air, surrounded by hot exhaust and an engine with no airflow. Access to fresh air helps keep the wastegate at a safe operating temperature, extending its life and reducing the risk of failure.

Turbosmart tests and designs external wastegates to cope with extreme heat. Carefully selected materials and tolerances ensure that they are up to the job and can handle the heat of the most severe applications.

4. External Wastegates are responsible for turbo flutter.

The sound of turbo flutter, or compressor surge, is sometimes referred to as ‘wastegate chatter’ – but this noise has nothing to do with the wastegate. As the name suggests, compressor surge occurs on the compressor side of the turbocharger – outside air is drawn in and compressed for the engine to consume and used on the turbine side, where exhaust gasses spin the turbine wheel to operate the compressor. That fluttering sound, which typically occurs when the throttle is suddenly closed, is the sound of the turbo trying to push air into the engine but failing, so the compressor blades ‘chop’ through the air. You can read more about this phenomenon here.

5. Wastegate spring pressure is the highest boost level you can reach.

False! Wastegate spring pressure is the lowest boost level you can reach. Using a boost controller, you can quickly increase boost pressure over wastegate spring pressure. However, you can’t achieve a maximum boost level under the wastegate’s spring pressure.

If a wastegate is fitted with springs rated to 7PSI, it will open when it receives 7PSI of pressure from the actuator. Any pressure lower than that will not overcome the spring force, and it will remain closed.

How Does a Boost Controller Work?

October 27, 2021 No Comments
Electronic Boost Controllers

What is a Boost Controller?

A boost controller is a device that helps regulate the amount of boost pressure created by your turbocharger. Boost pressure forces more air into your engine, ultimately creating more power. The more air you can force into your engine, the more power it can produce. However, too much boost pressure can damage your engine and cause severe damage. That’s where a boost controller comes in. It allows you to dial in the perfect amount of boost pressure for your particular setup and ensures that your engine stays safe while still making as much power as possible.

No matter the boost controller you choose, it’s essential to ensure that it’s installed correctly. Incorrect installation can lead to engine damage and decreased performance. If you’re not sure how to install a boost controller, it’s best to consult with a professional. With the right boost controller, you can take your car’s performance to the next level!

Why use a Boost Controller?

If you have a turbocharger, then you know that they can be a great way to improve your car’s performance. But what if you want to take things to the next level? That’s where a boost controller comes in.

A boost controller is a device that allows you to manually adjust the amount of boost pressure that your turbocharger produces. By doing this, you can fine-tune the performance of your engine to get the most power and efficiency out of it.

There are many different types of boost controllers on the market, so it’s essential to research and find one that will work best for your particular setup. But if you’re looking for a way to take your turbocharged car’s performance to the next level, a boost controller is something to consider.

The Primary Function of a Boost Controller

A boost controller controls the amount of manifold pressure by changing the pressure going to the wastegate. For example, suppose you wish to increase your boost pressure above your normal wastegate actuator pressure (typically 7psi). In that case, the boost controller must accurately modify the pressure signal the wastegate actuator receives by venting an adjustable amount of pressure, forcing the turbo to produce the new, increased boost level.

Boost Controller Illustration

The Two Types of Boost Controllers

There are two main types of boost controllers: manual and electronic. Mechanical boost controllers are the simplest type and use a spring-loaded valve to regulate boost pressure.  Electronic boost controllers are more complex and use a computer to control the boost pressure. They offer more precision and are generally considered the better option.

Both types of boost controllers have their advantages and disadvantages. Mechanical boost controllers are generally less expensive and easier to install, but they can be less precise than electronic boost controllers. Electronic boost controllers are more expensive and require more installation, but they can provide better boost pressure regulation.

1. Mechanical (Gated) Boost Controllers

The Turbosmart Gated Boost Control Valve range is one of the best value for money horsepower upgrades that you can make to your turbocharged petrol or diesel engine vehicle—designed to offer the option of up to two boost settings, set by the driver and controlled via a switch. They are easy to fit, simple in operation and require little maintenance resulting in an excellent dollar for horsepower solution!

The range includes our exclusive Gate feature, which improves turbo response by up to 800 rpm earlier in the rev range – this means that you can increase the performance and response from your engine without even raising the maximum boost level.

2. Electronic Boost Controllers

The solutions that the electronic boost controllers offer are a far more sophisticated host of boost settings mapped against different triggers such as:

  • Gear change
  • Time
  • RPM or a manual switch

Furthermore, they require a higher level of technical knowledge to be fitted but offer greater flexibility and countless features.

Choosing the Right Boost Controller for Your Application

The table below lists all the functions available with each Turbosmart Boost Controller. It will help you decide which Boost Controller is suitable for you.

Boost Controller Guide

The Turbosmart eBoost range of electronic boost management systems is one of the most popular, powerful, and user-friendly ranges of electronic boost controllers on the market.

Engineered to win, the eBoost controllers give you the ultimate control over the boost curve with innovative features designed for one thing – performance. All Turbosmart e-Boost controllers feature our exclusive adjustable gate pressure feature, which improves turbo response by up to 1000 rpm earlier in the rev range.

More importantly, this means that you can increase the performance and response of your engine without even raising the maximum boost level. Turbosmart e-boost controllers also allow the user to control three different aspects of the boost curve;

  1. The maximum boost pressure (set point),
  2. The spool-up rate of the turbocharger (gate pressure)
  3. The reaction time of the controller (sensitivity).

Each unit is housed in an aluminium case for durability and strength, while a simple three-segment display is used for easy viewing and navigation in all extreme driving conditions.

Is a boost controller necessary?

A boost controller is not strictly necessary for your car, but it can make a big difference in how well your car performs. Boost controllers allows you to regulate the amount of boost that is sent to your engine, which can help improve your car’s power and acceleration. If you are looking for ways to get the most out of your car, then a boost controller is a good option to consider. There are a few different types of boost controllers on the market, so you will need to do some research to find the one that is best for your car. Boost controllers can be found online and in many automotive stores.

How Expensive are Boost Controllers?

Boost controllers are not cheap. They can range in price from around $200 to over $1,000. However, they are an important part of your car’s turbocharger system and can help increase the performance of your car. Boost controllers can be simple mechanical devices or they can be electronic. Electronic boost controllers are more expensive, but they offer more control over the boost pressure. Boost controllers are an important part of any turbocharged car and can help you get the most out of your car’s performance. Thanks for reading!

5 Facts About Blow Off Valves That Are Wrong

October 26, 2021 No Comments

What is a Blow Off Valve?

A blow off valve (BOV) is a device that helps regulate pressure in an engine by allowing air to escape when needed. By doing so, it prevents damage to the engine and helps keep it running smoothly. Blow off valves are often used in turbocharged engines, as they can help prevent “boost creep” (when too much boost pressure builds up in the engine).

Blow off valves are typically located between the air intake and the throttle body. When the throttle is closed, the pressure in the intake manifold can increase, causing the blow off valve to open and release some of the pressure. This helps to prevent boost creep and keeps the engine running smoothly.

While blow off valves are not required for all engines, they can be a worthwhile addition for engines that are subject to high levels of stress (such as turbocharged engines). By helping to regulate pressure, blow off valves can help extend the life of your engine and keep it running at its best.

Laying Some of the Most Common Misconceptions to Rest

Turbosmart was built upon the blow off valve (BOV ), also known as the diverter valve). It was the first product we ever made. Since then, we have been endlessly working to improve and perfect it. As a result, we’ve learnt a thing or two over the years, and we want to put some of the most common misconceptions to rest.

1. Cars Don’t Have Blow off Valves From Factory, So I Don’t Need One

Cars not having blow off valves may have been true back in the early days of turbo vehicles. At the time, most factory turbo cars did not come with a factory blow-off valve. However, these early turbo cars were also running relatively low boost levels.

Today, most modern turbocharged cars do have a blow off valve from the factory. However, it recirculates the vented air, so it doesn’t give the characteristic sound of a vent-to-atmosphere blow off valve. Recirculating BOVs are sometimes called bypass valves (BPVs). Nevertheless, standard BOVs/BPVs are often very basic. Additionally, sometimes BOVs/BPVs are made of plastic, suffer from inadequate valve response, and do not cope well with increased boost levels.

However, it is essential to note that these cars run blow off valves to prevent compressor surges, leading to the next misconception.

2. Turbo Flutter is Harmless

That fluttering noise that some turbocharged cars make when the throttle is suddenly closed, such as during gear changes, results from a compressor surge.

It’s a reasonably complex phenomenon which we explain in far more detail here. In short, flutter is the sound of a turbocharger trying to push air. However, failing due to closed throttle. Therefore, it dramatically increases the load on the bearings of the turbo.

If it occurs at higher engine loads or boost levels, it can cause premature wear to your turbo. To sum up, a BOV prevents turbo flutter by venting the air pressure that causes surge.

3. Blow off Valves Only Vent to The Atmosphere

The Holden Commodore VL Turbo is an example of an early factory turbo car with no BOV. Modified VLs are known for their fluttering sound. However, they ran low boost pressures from the factory.

This misconception is likely because of the characteristic sound of a blow off valve, which is that a vent-to-atmosphere valve creates loud, sharp “Pssh”. Recirculating or plumb back valves exist and are very popular; however, you don’t hear them. As mentioned above, most modern factory turbo cars have a recirculating blow-off valve as standard.

Turbosmart manufactures high-performance aftermarket recirculating blow-off valves as well as the more noticeable vent-to-atmosphere versions.

Our Dual Port valves feature a split between recirculating and atmospheric operation. Therefore, Turbosmart Dual Ports provide quiet, computer-friendly operation on low boost. In contrast, that classic vent-to-atmosphere sound at a more significant boost. Our Type 5 Dual Port even lets you switch between fully vent-to-atmosphere, fully recirculating, or a mix of both as you wish. They are explained here in more depth.

A Turbosmart Type 5 Plumb Back BOV recirculates 100% of vented air back to the car’s intake.

4. A BOV is the Cause of a Boost leak if it Leaks in a Smoke Test 

Smoke tests are often used to diagnose boost leaks by pressurizing the turbo system with smoke. Additionally, observing where the smoke is escaping can help pinpoint the source of the leak. However, it’s important to remember that this test does not replicate actual driving conditions.

Typically in a smoke test, the BOV is pressurized through the plumb back port, which never happens when driving. This means air can leak out of areas that wouldn’t be sealed under normal operating conditions.

Another form of test which is not an accurate means of testing for boost leaks is the soap test. A soap test is similar to a smoke test, except soapy water is sprayed on the BOV and around the turbo system. If there are any leaks, bubbling will occur. However, this test is inaccurate because it does not consider the pressure differential between the atmosphere and the turbocharger.

Overall, neither of these methods is an accurate way to diagnose boost leaks. The best way to test for boost leaks is through a pressure test, which can be conducted with a hand-held vacuum pump or a professional dyno machine.

5. A Blow off Valve Needs an O-ring to Seal

Some aftermarket blow off valves require a rubber O-ring to seal the piston with the valve body. It is further preventing leakage, which will perish or become displaced over time. That means the valve will have to be disassembled and that tiny O-ring replaced to ensure it continues operating as it should. Turbosmart’s blow off valves are precision machined to mere fractions of a millimetre to ensure they seal without the need for a delicate rubber O-ring. This makes them much more durable.

Why you may want to Consider Installing a Blow Off Valve

If you’re thinking about installing a blow off valve on your car, there are a few things you should know first. Here are the key takeaways:

1. Blow off valves can improve your car’s performance by allowing air to flow freely through the engine.

A Look Inside the GENV External Wastegate

October 23, 2021 No Comments
GENV Wastegates

Released at SEMA in 2017

Released at SEMA in 2017, the GenV wastegate range was part of 3000+ new products unleashed on the market. Just another wastegate, right? Wrong! The GenV External Wastegate range has proven itself in the heart of Motorsport time and time again since its release. Want to know how we did it and what makes it different?

20 Years of Research & Development

Going back to the drawing board on an entire wastegate range with 20 years of research and development, manufacturing experience and feedback from customers, racers, and motorsport engineers all around the globe meant a severe rethink – not just a tidy up! The GenV range is more than a design change or minor upgrade; it’s an architecture to build on. Taking all that feedback and experience on, the only thing our engineers kept was the inlet & outlet flange orientation so that just about anyone could benefit from the new advanced design.

Developing the GenV External Wastegate

Developing the GenV External Wastegate range was an intensive 2-year project, taking in years of data collection and market analysis. Each housing size from the traditional two-bolt 38mm housing, through all V-Band solutions from 40mm up to 60mm, were CFD optimised to ensure no matter which sizes our customers purchased, they had the highest possible flowing valve on the market. Many CFD and analysis design features were incorporated at this time, other than the wastegate body itself. The observant eye will notice features on both the valve itself and the valve seat as well.

Why is a High Flowing Valve Important?

 In simple terms, the more your valve flows, the more control you have. Increasing the flow increases the ‘tuning window’ available on a given set-up, further increasing with improved wastegate priority. A well-man prioritised, high-flowing wastegate allows you to fit a smaller gate, and remember, #SmallerLighterFaster.

Market-leading Thermal Performance

The design features on the valve also aid with the next part of the design process, ensuring the GenV range has market-leading thermal performance. There are a few principles to ensuring you have the most thermally stable and reliable wastegate on the market, and they are; 

  1. Maximising energy transfer through the gate itself.
  2. Reducing the amount of heat that will then get to the actuator housing.
  3. Ensuring the actuator itself is robust.

Minimising Heat Transfer into the Actuator Housing

A high flowing wastegate is an efficient one, and this means less heat left in the gate, assuming all other things are equal. On top of this, computer modelling and analysis allowed our Engineers to adopt design features that minimised heat transfer into the actuator housing and finally ensured the springs and the diaphragm itself was ahead of the game. Further to the basic design, Thermal Composite Insulators have introduced either side of the valve guide, further reducing the thermal transfer.

Cycle Testing the GENV External Wastegate at 1200° C (2192° F)

With Thermal Performance in hand & drastically improved over our nearest rival, the entire concept was put the test – Over 3 Million cycles were performed over our various wastegate sizes. Cycle testing, at 1200° C (2192° F) was always part of the planned program and each variant was put to the test and all predictions and modelling validated on gas stands in-house. To put that into perspective, the most demanding motorsport expectations are generally around 1100° C (2012° F) so we wanted to make sure our customers had headroom.

Features & Benefits

  • Class-Leading Thermal Performance
  • Class-Leading, CFD & Validated Flow Performance
  • Class-Leading Fatigue Resistance
  • CNC Construction with Nitronic 60 Valve Guide
  • High Temp 347 Stainless Steel Body

Advanced Features & Benefits

  • Thermal Composite Insulator
  • Modular, 360° Rotatable Housing
  • Liquid Cooling Provision
  • Mil-Spec Nomex Diaphragm
  • EV8 High-Performance, Forged and
  • Hard chromed Valve
  • Strap type V-bands
  • A myriad of available spares, accessories, and upgrade kits

GENV Actuator Options at a Glance

Standard

Designed to be the highest performing actuator housing on the market. Our testing indicates that our “off the self” housing quickly has the best control and highest fatigue resistance. Thermal gas stand testing reveals that this housing outperforms the nearest competitor by over 200% – this is WITHOUT using the standard optional water cooling. Add in the 360° Rotatable Housing, all spring combinations included and 1/8 NPT pressure ports, and you have a formidable foundation to build the range upon.

Motorsport

For the most demanding environments on earth, you can’t go past the Motorsport variant of our GenV External Wastegate range. On top of GenV’s market-leading thermal stability and performance, the motorsport version includes a CFD driven heat sync, further distancing the actuator from the source of heat. The heat sync is designed to dissipate the energy into the surrounding air while still proving uncompromised valve actuation and performance.

Compressed Gas

While the more common boost control strategies involve the use of an actual boost signal from your turbocharger to move the actuator around, a compressed gas set up (more commonly known as Co2, due to the gas most often used) uses an independent signal reference at much higher pressures for more control and a larger ‘tuning window’. The hardware consists of a much softer spring; however, the diaphragm and actuator housing are subjected to high pressures and require quite specific components that the GenV Compressed Gas variant is built around.

Position Sensor Options

Available for the GenV standard, Motorsport and Compressed Gas Version, is a wastegate position Hall Effect (HE) sensor. Data is power as they say, and the wastegate valve position is no different. The GenV position sensor utilizes a unique hall effect, non-contact position technology that allows the GenV range to run housings with no holes to leak boost, while not being affected by thermal demands like a contact sensor would. No leaks, no melting, just reliable data.

(HP) High Pressure

If 26 psi of base mechanical pressure isn’t enough, the GenV range still has you covered with the HP variants. With options up to 50psi of base mechanical spring pressure, the HP is where it is at for high-pressure petrol & diesel engines. Remember this 50psi is just base pressure – With some reference signal manipulation and boost control strategy, you could be talking 2-3 times that in actual manifold pressure if desired.

How Does An Intercooler Work?

October 19, 2021 No Comments
Turbosmart Intercooler

What is An Intercooler?

An intercooler is a device that helps to cool air as it passes through the engine of a car or truck. By cooling the air, the intercooler helps improve the engine’s performance and prevent overheating. There are two main types of intercoolers: air-to-air and air-to-water. Air-to-air intercoolers use air to cool the air passing through the engine, while air-to-water intercoolers use water to cool the air.

Intercoolers are often used in high-performance cars and trucks with turbocharged or supercharged engines. By cooling the air before it enters the engine, the intercooler helps to increase the amount of air the engine can take in. This, in turn, helps improve the engine’s power and performance. Intercoolers are also sometimes used in diesel engines.

What is the Purpose of An Intercooler?

The primary purpose of an intercooler is to cool the air that the turbocharger or supercharger has compressed before it enters the engine. By cooling the air, the intercooler reduces the chances of knocking and allows for more air to be forced into the engine, which can increase power output. Additionally, cooling the air can also help reduce emissions.

An intercooler can be used on both turbocharged and supercharged engines. When used on a turbocharged engine, the intercooler is located between the turbocharger and the engine. On a supercharged engine, the intercooler is typically located between the supercharger and the engine. Intercoolers can be air-to-air or air-to-liquid. Air-to-air intercoolers use ambient air to cool the compressed air from the turbocharger or supercharger. Air-to-liquid intercoolers use a liquid coolant to cool the compressed air from the turbocharger or supercharger.

How Does An Intercooler Work?

An intercooler uses a series of fins and plates to dissipate heat. The air or fluid is forced through the intercooler, and the fins help to transfer the heat from the air or fluid to the surrounding atmosphere. This process helps to keep the air or fluid cool, so the engine or system can run more efficiently. Additionally, an intercooler can prolong the life of an engine or system by preventing overheating.

When the air is compressed by a turbo/supercharger, it gets hot very quickly. Therefore, its temperature climbs and its oxygen content (density) drops. When the air is cool, an intercooler provides a denser, more oxygen-rich air to the engine. Therefore, improving the combustion by allowing more fuel to be burned. 

It also increases reliability as it provides a more consistent temperature of air intake to the engine. This allows the air-fuel ratio of the engine to remain at a safe level.

The Two Type of Intercoolers

1. Air-to-Air Intercooler

An air-to-air intercooler is a device used to cool the air compressed by a turbocharger or supercharger. Intercoolers are a vital part of forced induction systems, as they help reduce the engine’s intake temperatures, which in turn helps to increase power and efficiency. There are two main types of air-to-air intercoolers: front mount and top mount. Front-mount intercoolers are usually more extensive and effective than top-mount intercoolers, but they can be more challenging to install. Top-mount intercoolers are easier to install, but they may not be as effective at cooling the air.

Air-to-air intercoolers work by passing the compressed air from the turbocharger or supercharger through a series of fins or coils. These fins or coils help dissipate the heat from the air, which helps to cool it down. The cooler air then flows into the engine, where it can help to increase power and efficiency. Intercoolers can be made from various materials, but aluminium is often used because it is lightweight and has good thermal conductivity.

If you want to add an air-to-air intercooler to your forced induction system, there are a few things to consider. First, you need to make sure that the intercooler will fit in the space that you have available. Second, you must decide whether you want a front-mount or top-mount intercooler. Finally, you need to choose a material that will be durable and effective at cooling the air.

Advantages:

  • Simplicity
  • Lower cost 
  • Less weight

This also makes it by far the most common form of intercooling.

Disadvantages:

  • Longer intake length due to having to get the intercooler to the front of the car
  • More variation in temperature than air to water.
Placement

The best placement for an air-to-air intercooler is at the front of the vehicle. The “front-mount” is considered to be the most effective placement.
When the engine layout or type of the vehicle do not permit the “front-mount” placement, the intercooler can be mounted on top of the engine or even on its side. These placements will often require additional air ducts or scoops to route the air directly into the intercooler. However, these are not considered practical. This is because the airflow is not as effective. Thus, the intercooler can suffer from heat soak from the engine when the external airflow drops.

2. Air-to-Water Intercooler

An air-to-water intercooler is a type of intercooler that uses water to cool the air charge coming from the turbocharger or supercharger.

The main advantage of an air-to-water intercooler over a traditional air-to-air intercooler is that it can provide a much denser charge of air to the engine. This results in more power being produced by the engine, as well as increased fuel efficiency.

There are several disadvantages to using an air-to-water intercooler, however. One is that they are generally more expensive than traditional air-to-air intercoolers. Another disadvantage is that they require a constant supply of water, which can be difficult to maintain in some climates. Finally, air-to-water intercoolers can be more difficult to install than traditional air-to-air intercoolers.

Advantages:

  • This makes them well suited to complex installations where space, airflow and intake length are an issue. Water is more efficient at heat transfer than air. Thus, it has more stability to be able to handle a broader range of temps.

Disadvantages:

  • However, this system requires the added complexity, weight and cost of a radiator, a pump, water, and transfer lines. Typical applications for these are industrial machinery, marine and custom installs that don’t allow the easy fitment of an air to air, such as a rear-engined
  • vehicle.
Placement

The air to water can be mounted anywhere in the engine bay as long as the radiator is mounted in a position with good airflow or a Thermo fan attached to it.

How Do You Get & Retain Sponsorship?

February 25, 2021 No Comments
Turbosmart Sponsorship

Turbosmart Sponsorship

This article aims to clarify any misconceptions about the sponsorship process. Also, answer any questions you might have about applying for Turbosmart Sponsorship. Every day, performance parts manufacturers get tons of mail requesting various sponsorship levels. Unfortunately, most applicants end up in the “rejected” basket. Turbosmart’s Marketing Manager sheds some light on the sponsorship issue and offers valuable insights and advice for potential applicants.

Give Me Some Free Stuff!

Sadly, that’s the main message of a large percentage of, consequently rejected, sponsorship enquiries, as every business-savvy person will tell you that there’s no such thing as a “freebie”, and a Sponsorship is no exception. Like any other business agreement, Sponsorship has to benefit both parties.

Three Magic Letters – ROI

Every manager in charge of sponsorships will have to, at some point, account for every sponsorship dollar spent, be it in the form of a product or cash. The amount of publicity/branding/interest the sponsorship has generated has to be reflected in sales – the value of these sales over the initial sponsorship value is what we call Return On Investment or ROI.

It’s A Two-way Street!

This is the most important yet often overlooked aspect of any sponsorship deal. The principle of “something-for-something” is a simple one, and once understood and applied, will go a long way towards securing a sponsorship deal.

How Does Sponsorship Work?

A sponsor provides the sponsored driver with goods/money. A sponsored driver, in turn, provides his services to the value of the goods/money received. The benefits from exposure/publicity are shared between the sponsored driver and the sponsor.

Think of it as a loan from a bank. Since you know the bank will provide you with the funds, you need to achieve your goals. You must repay the loan, plus any interest accrued, over a specified period.

Your Sponsor is Like the Bank

They invest in you and your goals. You have to repay that loan in services that you provide – Which is why we ask you for things like:

  • Signage on your car.
  • Signage in your pit area.
  • Listings on your website.
  • Credits in the magazines.
  • Mentions and endorsements during race meet and shows.
  • Being available for product launches.
  • Monthly updates with photos, etc.

The best part of the deal is that the interest accrued that you would normally have to pay to the Bank is actually a profit shared between the sponsor and yourself. That profit is publicity that you receive from winning races, shows, being featured in magazines etc. By increasing your profile, you also increase the brand awareness of your sponsor’s products – hence, both parties share the benefits.

Still Unsuccessful!

At this point, some of you might think that my application followed all those rules, but it was still unsuccessful. There might be a good reason for that, and one that can be easily avoided with a little bit of homework. Before submitting your application, do some research. Find out what companies are active in your type of motorsport, who they sponsor, and their expectations.

Every Company Wants to Sponsor Winners

It’s because they have the highest profiles, get the most publicity etc. But sponsoring someone who is No.1 is difficult – they’re already sponsored and expensive – the best demand the highest rates. So smart sponsors seek out, and coming drivers with the potential to be future champions and secure the deal before they reach that No.1 spot. It is essential to consider this when applying for sponsorship. For example, approaching a company that is a major sponsor of a current champion will most likely end up in disappointment simply because there’s nothing you can offer them that they are not already getting from their champion. A much smarter move would be to approach a competing company and offer them a chance to be a part of the team that might knock the reigning champion off his perch within a season or two.

Here is a Quick List of Things That can make OR break a Successful Sponsorship Deal

Remember, it’s a two-way street, and both parties must benefit from the relationship.

Submitting a Proposal

  1. ALWAYS address it to the right person – marketing, sponsorship or pr manager; otherwise, your application might end up in the short-term disposable filing system (rubbish bin).
  2. DO submit a professional-looking proposal outlining all the benefits to the sponsor.
  3. PLEASE specify where and how you want to display the sponsor’s logos and signage.
  4. DO mention any past projects you’ve completed or raced. It gives the sponsor an idea as to your commitment and success ratio.
  5. MAKE SURE to provide references from other sponsors.
  6. DO provide a detailed plan of the vehicle build-up and race/show attendance, but…
  7. NEVER make it too long. Nobody is going to read a proposal that’s more than ten pages long.
  8. DO NOT approach two competing companies for sponsorship on the same car.
  9. PLEASE DON’T promise things you can’t deliver. If you promise to attend all the race meetings in a given season and your car is not ready at the beginning of the season, you’ve effectively defaulted on the deal.

During Your Sponsorship Period

  1. DO fulfil all your obligations. Whenever you’re in the public eye, you’re representing your sponsors as well as yourself.
  2. ENSURE all your team members and pit crew are aware of the sponsorship requirements.
  3. It’s IMPORTANT; you provide your sponsors with all your race results, images, video footage and media articles regularly. They need these to use in their advertising, promotions etc.
  4. ALWAYS keep in contact with your sponsors during the season. You might get introduced to other potential sponsors but….
  5. DON’T approach a company for sponsorship while their competitor sponsors you.
  6. DO NOT change/move your sponsors’ signage without their prior knowledge.
  7. DON’T try to renegotiate your deal half-season just because you’ve won a couple of races.
  8. NEVER bad-mouth your sponsors publicly. If you have a problem, sort it out with the sponsor directly. Remember, other potential sponsors, are watching your actions and will base their future sponsorship decisions on what they see.

Boost Spiking Explained

November 26, 2020 No Comments
Electronic Boost Controllers

Boost Spiking Defined

Boost spiking is defined as a momentary overshoot in boost pressure over the desired boost level. Thus, a boost spike results from the boost controller holding the signal to the wastegate actuator / external wastegate for too long.

Therefore, clamping the signal to the wastegate can increase the response of the turbo system and reduce lag. This effectively keeps the wastegate shut and not allowing it to bypass any exhaust. Thus, not wasting any exhaust energy.

Boost Spiking in Pressure

A spike in pressure can be the desired effect as it gives the engine a significant increase in midrange torque without placing a lot of strain on the engine. Thus, higher boost pressure is only reached momentarily at mid-range RPM, rather than having that boost level through the rev range. On the other hand, some cars from the factory have boost pressure spikes to make the engine feel more responsive and powerful in the midrange.

A wastegate needs to be given time to “catch” the boost curve. To eliminate a boost spike, the wastegate must begin to open before the target boost by a certain amount of time, depending on the turbo system. To sum up, if the wastegate starts to open at target boost, a boost spike will occur as the wastegate will need some time to open to the correct valve height to divert enough exhaust gas to maintain the desired boost level.

Boost Spiking Explained Graph

Turbosmart e-Boost Range

The Turbosmart e-Boost controller range has a gate pressure function that allows the user to choose what pressure the controller will allow boost pressure to reach the actuator. Setting the gate pressure at the optimum level will result in the best boost response from the turbo system. Set the gate pressure too high and a boost spike will occur. Set it too low, and the boost response will be lower. 

Tuning the Gate Pressure

The gate pressure is tuned by first setting the gate pressure at 3 PSI lower than what the target boost pressure is.

  1. If the target boost pressure is 18 PSI, set the gate pressure to 15 PSI.
  2. If an undesirable spike occurs, reduce the gate pressure by 1 PSI and check whether a spike occurs again.
  3. Repeat the steps until the spike is gone.
Boost Pressure Graph

Turbosmart Manual Boost Controller Range

The Turbosmart manual boost controller range has an inbuilt gate system which is set at 3 PSI. Meaning that below 3 PSI, the controller will clamp the signal to the wastegate, keeping it closed. Furthermore, removing the gate system by removing the ball and spring can eliminate the spike if an undesirable boost spike occurs.

Gate System Removal – Manual (Gated Boost Controllers)
The gate system can be removed by the following steps below.

  1. Firstly, allow the engine to cool down before removing the Boost Tee from your vehicle.
  2. Next, identify the input nipple with the restrictor at the end. Loosen the input nipple and remove the ball and spring.
  3. Thirdly, check that the internal air passages are clear and free from debris.
  4. Re-install the boost controller by following the instructions for your setup
  5. Lastly, you will need to re-adjust your boost settings after the removal of the gate.

Tech Tip: Manual Boost Controller Troubleshooting

The following points should be checked:

  • Firstly, if you find that your engine is developing excessive boost.
  • Secondly, if the boost pressure is fluctuating or the desired boost level cannot be achieved.
  1. Check that the boost controller is installed so that the arrow points toward the wastegate actuator.
  2. Inspect the joining hoses for splits, cracks or loose connection and are the correct size for the application.
  3. Check to see if the boost controller is blocked or contaminated with dirt or debris.
  4. Ensure that there is nothing but the boost controller in the hose between the pressure source and the wastegate actuator, ie tee pieces for boost gauge or to factory boost solenoid.
  5. Lastly, pressure test the wastegate actuator for leakage.

10 Frequently Asked Questions About Turbosmart’s eBoost2 Controllers

November 19, 2020 No Comments
eboost2

eBoost2 Controllers

Turbosmart’s eBoost range of electronic boost controllers gives you the ultimate control over your boost curve. Turbosmart electronic boost controllers allow you to control three individual characteristics of your boost, by adjusting three easy to set parameters: The maximum boost pressure (set point), The spool-up rate of the turbocharger (wastegate pressure), and the reaction time of the controller (sensitivity).

1. Can I fit and setup an eBoost2 or eBoost STREET myself?

eBoost2 controllers are fully-featured programmable electronic devices. Turbosmart recommends using a reputable, qualified technician to install e-boost 2 controllers. If you are a competent, technically-savvy DIY installer. GREAT!  Then we suggest you carefully read and follow the instructions included with the unit.

2. If I’m not using external switching or aux output should I leave those wires disconnected?

You only need to connect the wires that you’re actually using. For example, if external switching an aux output is not being used leave the green, orange and white wires disconnected and insulate them from each other.

3. What is the basic connection method for an eBoost2 solenoid into an external wastegate?

  • Port-3 goes to pressure.
  • Port-2 goes to the bottom port.
  • Port-1 vents to atmosphere.

This is a basic setup and also the recommended starting point for boost control. The other hook up methods are designed to combat issues like high exhaust backpressure. Please see pages, 16-17 for all recommended solenoid connection methods.

4. I want to run a switch that has a bulb to indicate the switch is on. How much current can you safely pull through the green switching wire?

Please, don’t do it! The switching wires are only to see the ground. You will cook your eBoost controller quicker than you can say “WHOOPS!” If you want to run an indicator light. It’s imperative that you MUST use an isolation relay for the bulb’s circuit.

5. I have a turbocharged motorcycle with a Turbosmart wastegate and want to install an eBoost2 controller but I’m worried that it’s not waterproof.

Turbosmart’s eBoost two controllers are viral on turbocharged motorcycles. This is mainly because of their ability to provide six stages of sequential boost control. Most users mount them up on the triple clamps. An eBoost2 is NOT waterproof! However, with careful installation and a little silicone, they are quite water-resistant. This is something a lot of our customers can attest to.

turbo Charged Motorcycle eboost2

6. How does eBoost2 know what gear it is in if I change gears while the power is shut off? Is there a “reset” feature or does it default to a certain point upon power-up?

eBoost two controllers are always looking for a ground signal to shift. For Example: If you turned the bike in 3rd gear, it’d only be at the setpoint.

  1. Since it has not seen a rising edge ground signal.
  2. It will always start from SP1 when starting up. If the bike is always started in neutral, then it should perform flawlessly.
  3. Another option would be ESP, as it looks for a continuous ground signal from each wire rather than a momentary ground. However, this will limit the number of boost settings to 4.

7. I’m re-mounting my eBoost2 and I don’t want to lose the current setup. Will the settings be retained with the unit unplugged?

No! You won’t lose anything if you unplug your eBoost2. However, if you are worried, take 5-10 minutes and note down all your settings. This will be helpful if you do accidentally change something.

8. After installing an eBoost2 / eBoost STREET my engine is over-boosting/under-boosting.

  1. First, check that the eBoost solenoid is installed correctly.
  2. Then, ensure the factory boost control solenoid is not connected to the hose between the pressure source and the wastegate actuator.
  3. Ensure the length of the wastegate actuator rod has not been modified. Please, refer to the manufacturer’s specifications. If the over/under/irregular boost is still occurring…
  4. Check if the eBoost solenoid is not blocked or contaminated with dirt, oil build-up or debris.
  5. Check the joining hoses for splits, cracks or loose connections. Ensure they are not blocked, kinked or restricted, particularly if the existing hose was reused.
  6. Pressure test the wastegate actuator for leakage. There is a possibility that the diaphragm or housing may be cracked or split. If the over/under/ irregular boost is still occurring…
  7. Ensure the smooth and free operation of the wastegate arm in the turbo exhaust housing.
  8. Make sure to check that the hose between the e-Boost and the inlet manifold is not obstructed, broken or kinked.
  9. Next, check that the OBS is higher than the boost pressure you aim for.
  10. Check the Blow Off Valve for leakage. Some are used as over-boost valves. If the over/under/ irregular boost is still occurring…
  11. The gate pressure may be set too close to your actual boost pressure. Ensure correct sensitivity setting.

9. Do I need to check the Air-Fuel ratio while setting my boost pressure?

Yes. Any increase in boost pressure can cause the engine to run “LEAN.” Thus, resulting in possible engine damage.

10. What’s EMI and RFI and do they have any effect on my eBoost2?

There seems to be a cloud of mystique surrounding the EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference.) Most common issues occur with some people calling it a fantasy and others blaming it for all of their car’s problems. The truth is, while EMI may not be the source of all evil. It is very real and it does have an adverse effect on sensitive electronic devices.

What is the Source of EMI?

The source of EMI is any object that carries rapidly changing electrical currents in cars. The most common source of EMI is an aftermarket ignition system. It is a proven fact that the ignition system, especially solid core plug wires can transmit EMI into the vehicle’s electrical system. This causes erratic behaviour in electronic devices like ECUs or electronic boost controllers.

How to Reduce EMI?

  1. The first and most important step in reducing EMI is to follow the ignition system installation instructions. They must be followed EXACTLY to ensure all the electronic devices are wired properly.
  2. Using helically wound spark plug wires can reduce EMI transmission as does shielding any sensitive electronic devices and their wiring. However, the simplest and often most effective way of avoiding EMI is careful planning and routing of the entire ignition system away from all other wirings.

How to Reduce the Noise effects of EMI?

Aftermarket ignition systems, especially CDI, can create large amounts of electrical noise. Noise filters such as the MSD noise capacitor (#8830) can be wired into the power supply of the ignition system to eliminate large voltage fluctuations in the vehicles electrical system.
Connecting the ground wires of an eBoost2 directly to the negative terminal of the car battery can also reduce the effects of EMI. This is especially important when the battery has been relocated to the boot or trunk of the vehicle.

Installing Diodes to Reduce Risk of EMI

Installing diodes into the ground wires of an eBoost2 loom can effectively reduce the risk of EMI affecting the functionality of an eBoost2.

  • The diodes will restrict the flow of current in one direction.
  • Therefore, the diodes only need to be installed on the ground wires that are being used. For example, Diodes only need to be placed on the trigger wires if external triggering is used.
  • The diodes need to be wired in so that the flow of current is away from the head unit. For example, The cathode is away from the head unit (As per the wiring diagram). The diode models that can be used are 1N4001 or 1N4002.

Use only resistor type relays when connecting the E-Boost2 to an auxiliary device. Normal relays can cause voltage spikes to an eBoost2.

Here is a handy self-help guide to helping you with your Turbosmart install and answers to some of the most frequently asked questions we get here. Turbosmart recommends that you get your products fitted and tuned by a qualified technician. If you choose to install the product yourself, ensure you have all the necessary tools and technical knowledge to perform this task.

Turbosmart’s “OPR T40” Oil Pressure Regulator is a game changer

SET UP OPR T40

 Why Turbosmart's OPR T40 Is a crucial component of any turbo setup?

In modern engines, high-pressure oiling systems are used to keep parts properly lubricated. While high engine oil pressures are perfectly suited for the internal parts of an engine, they often exceed the optimal thresholds of aftermarket turbochargers. When you have too much oil pressure going into the turbocharger, it can often exceed the maximum threshold of the internal seals of the turbo and can wreak havoc on its ability to properly oil itself. This is why it’s important to use an OPR T40 Oil pressure regulator to help combat this problem.

Let's take a closer look at how the OPR T40 plays a crucial part in Regulating Oil Pressure

A simple way of illustrating this example is the human heart. The oil supply is the “blood” to the turbocharger and the pressure is the force of the “heartbeat”; Too much pressure or too little pressure can mean death! This is where the OPR T40 comes into play. The OPR T40 serves as a true oil pressure regulator for the turbocharger. While it has been common practice to restrict the flow of oil to reduce pressure, this can be problematic.

The problem with using something like an orifice or other restrictor to achieve target oil pressure is a considerable compromise in oil flow. There is a significant difference between controlling flow and controlling pressure when it comes to oiling your turbocharger. Restricting oil flow favouring a lower pressure can be problematic and cumbersome, especially when oil pressure-demand inside the engine changes throughout the RPM range. Other factors like oil grade, viscosity, and even temperature can influence this fluctuation in oil flow and lead to unreliable pressure to the turbocharger when a restriction is used.

OPR T40 is Engineered to Have A Static 40PSi of Regulated Oil Pressure

Turbosmart engineered the patented OPR T40 to have a static 40PSI of regulated oil pressure. We found 40 PSI to be the sweet spot for most aftermarket turbochargers in our research and development. While the input oil feed pressure going into the OPR will change throughout the rev range, the flow will never be reduced, and the pressure will never be compromised. This provides the benefit of zero guesswork, reliable pressure, and no reduction in flow rate. The engine has the freedom to increase pressure as needed, and the turbocharger is unharmed in the process. It is one of our company’s proudest innovations, and it will surely meet the needs of many racers and builders around the world.

The Ultimate Guide to Changing a GenV Wastegate Spring

April 15, 2020 No Comments
Turbosmart External Wastegates - GENV Range

Innovative Way to Change A GenV Wastegate Spring

For years racers, tuners, and enthusiasts have wrestled with the complications of swapping springs on their external wastegates. Throughout the industry, old-school wastegate designs utilized a common multi-bolt cap design to gain access to the internal springs. Through years of research and development, Turbosmart has put its products through their paces and found an innovative way to simplify and improve this area of wastegate tuning; The threaded locking collar! 

With the introduction of the Comp-Gate 40 wastegate in 2010, Turbosmart introduced the first threaded locking collar design for the diaphragm housing. This new design simplified the process of opening up the wastegate and allowed users to quickly swap springs. Some additional benefits of the threaded locking collar are the reduction in overall wastegate size and substantially improved sealing of the diaphragm housing. 

If you are looking for the correct spring configuration for your particular GenV Wastegate, please refer to the spring chart below
