How does a Boost Controller Work?

This is a question Turbosmart gets asked all the time, How does a boost controller work? In this article, we provide you with all the information that you need to know about boost controllers for your turbo setup.

The Primary Function of a Boost Controller

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 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.

How does a boost controller work?

There are two types of boost controllers; mechanical and electronic.

Mechanical Boost Controllers

Offering up to two boost settings the mechanical (gated) boost controllers can easily be set and adjusted by the driver and controlled via a switch. They are easy to fit, simple in operation and require little maintenance.

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.

Boost Control Setup

Gated Boost Control Valve

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 a great 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.

Turbosmart e-Boost Range

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.

Engineered to win, the 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.

More importantly, this means that you can increase the performance and response from your engine without even raising the maximum boost level. Turbosmart e-boost controllers also allow the user to control 3 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 3 segment display is used for easy viewing and navigation in all extreme driving conditions.
