Boost Controllers for Turbo and Supercharged Vehicles

The best thing you can do to protect the longevity of your turbocharged or supercharged vehicle is to add a boost controller. Manual boost controllers or electronic boost controllers are a must. Protect your investment with a boost control unit from Vivid Racing.

The Function of a Boost Controller:

Without a boost controller, air pressure is fed from the charge air (compressed side) of the turbocharger directly to the wastegate actuator via a vacuum hose. This air pressure can come from anywhere on the intake after the turbo, including after the throttle body, though that is less common. This air pressure pushes against the force of a spring located in the wastegate actuator to allow the wastegate to open and bypass exhaust gas from reaching the turbine wheel. In this simple configuration, the spring's springrate and preload determine how much boost pressure the system will achieve. Springs are classified by the boost pressure they typically achieve, such as a "7 psi spring" that will allow the turbocharger to reach equilibrium at approximately 7 psi.

One primary problem of this system is the wastegate will start to open well before the actual desired boost pressure is achieved. This negatively affects the threshold of boost onset and also increases turbocharger lag. For instance, a spring rated at 7 psi may allow the wastegate to begin to (but not fully) open at as little as 3.5 psi. Achieving moderate boost levels consistently is also troublesome with this configuration. At partial throttle, full boost may still be reached, making the vehicle difficult to control with precision. Electronic systems can allow the throttle to control the level of boost, so that only at full throttle will maximum boost levels be achieved and intermediate levels of boost can be held consistently at partial throttle levels.

	Perrin Performance Manual Boost Controller Subaru WRX/STI 02-14 Model Number: ASM-INT-700 View Price The PERRIN manual boost controller is a simple inline device that allows the customer to adjust boost simply by shortening or lengthening the Boost controller body. Some boost controllers use a simple adjustable bleeder (similar to a jet on a carb, if you can remember that far back) and while this can control boost, these generally provide a falling boost curve. These systems cant adjust for more volume of air as the turbo starts to push more air. Some boost controllers use a ball and spring ...
