Boost Controller - Boost Controllers

Standard Boost Controller For a moderate boost increase you can not go wrong with this easy to use, bullet-proof boost controller. Great also for turbo diesel applications.

High Performance Boost Controller If instant boost is what you want, then that is what you get with this true amazing device. Generally know within the industry as the World's Best Manual Boost Controller. Excellent alternative and will often out perform most electronic controlers.

Dual Stage Boost Controller You've got the power with the flick the switch. Set two boost levels, less for launch, more for top-end power.

High Performance Dual Stage For a moderate boost increase you can not go wrong with this easy to use, bullet-proof boost controller. Great also for turbo diesel applications.

Fuel Cut Defender Finally a fuel cut defender that you don't have to hit fuel cut to adjust. Total control with its unique dual dials.

Shift / Knock Light A Shift Light that warns you of engine damage before it occurs. The TurboXS Knock Light is your best insurance to prevent unwanted expensive engine re-builds.

A turbo charger simply consists of an exhaust wheel and a compressor wheel connected together. Exhaust gases FROM EXHAUST MANIFOLD turns the EXHAUST TURBINE which in turn spins the COMPRESSOR WHEEL. The compressor wheel then crams more air into the intake, creating boost pressure.

If left alone, a turbo would just keep spinning faster and faster and could result in too much boost, which would cause engine components to fail. To regulate the amount of boost, a WASTEGATE FLAP VALVE is equipped on all turbo-charged cars. The purpose of the wastegate is to divert some of the exhaust away from the exhaust turbine (so it won't spin the exhaust wheel). A wastegate is controller via the WASTEGATE CONTROL CAPSULE, otherwise known as a wastegate actuator. It is simply a spring loaded diaphragm which opens when the intake pressure, supplied to the wastegate actuator via the PRESSURE SENSING HOSE reaches a certain pressure and diverts some of the exhaust away from the exhaust turbine. Suppose the wastegate is designed to open at 7PSI of boost, then when boost reaches 7.1PSI, the valve opens and the exhaust from the cylinders are diverted away from the exhaust turbine, and the turbo starts to slow down. When the boost drops to 6.9PSI, the wastegate closes and the turbo starts to speed up again. This happens rapidly and keeps boost regulated nicely at 7PSI.

The pressure at which the wastegate opens is the base boost pressure or wategate standard. Installing a boost controllers will allow you to run higher boost. A manual boost controller works by providing the wastegate a pressure which is lower than that in the intake manifold.
