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.

Grimmspeed founder, Justin Grimm, has always had a passion for cars. Just like most enthusiasts, he was satisfied with his vehicle's performance stock, but could not resist the urge to see just how much more potential was left untapped. After a few years of perfecting his ideas and techniques on his own personal vehicle, Justin decided to turn his passion into a career. He immediately realized the niche market for aftermarket performance and founded GrimmSpeed, initially performing all of the work out of his own garage. Enthusiasts quickly took to GrimmSpeed, and it became necessary to expand.
