How a Boost Controller Works

A boost controller controls the amount of manifold pressure by changing the amount of pressure going to the wastegate. For example; if you wish to increase your boost pressure above your standard wastegate actuator pressure (typically 7psi), the boost controller must acurately 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.

There are two types of boost controllers; mechanical and electronic. Mechanical (gated) boost controllers offer 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.

Electronic boost controllers are a far more sophisticated solution offering a host of boost settings mapped against different triggers like gear change, time, rpm or a manual switch. Electronic boost controllers require a higher level of technical knowledge to be fitted but offer a greater flexibility and countless features.

The Turbosmart Gated Boost Control Valve range is one of the best dollar for horsepower upgrades that you can make to your turbocharged petrol or diesel engine vehicle. Turbosmart Gated Boost Controllers offer 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 a great dollar for horsepower solution!

The range features 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.

Thanks to the Turbosmart Detent Adjustment System, stable and accurate increases in boost over wastegate A boost controller controls the amount of manifold pressure by changing the amount of pressure going to the wastegate.

For example; if you wish to increase your boost pressure above your standard wastegate actuator pressure (typically 7psi), the boost controller must acurately 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.

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

 

Turbosmart e-Boost controllers give you the ultimate control over the boost curve with  smart 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.

This means that you can increase the performance and response from your engine without even raising the maximum boost level. e-Boost controllers also allow the user to control 3 different aspects of the boost curve; the maximium boost pressure (set point), the spool up rate of the turbocharger (gate pressure) and the reaction time of the controller (sensitivity).

Each unit is housed in an aluminium case for durability and strength, while a simple 3 segment display is used for easy viewing and navigation in all extreme driving conditions.
