Centrifugal Supercharger Boost Control Kit by SmoothBoost

SmoothBoost is proud to offer the first ever fully electronic BOV for the Centrifugal Supercharger. Made right here in the USA, this new control kit removes the vacuum controlled Blow-off valve and gives you a precision electronically controlled valve to smooth out your torque curve so that it drives powerfully and predictable. That's not even the best part... With the turn of the SmoothBoost dial you can even set the level of boost you would like from your Centrifugal.

Say your car has a pulley making 15 psi but your engine can not handle that much boost without race gas and you want to be able to run pump gas without changing the pulley and tune. Easy, just turn the variable boost control dial down to the desired level of Boost. Then when you are ready for the higher HP simply turn the dial to MAX or use the configured input on a switch to have 2 preset boost levels and enjoy the full capability of your supercharger.

The SmoothBoost valves make for a much happier engine and drivetrain.  Instead of hammering boost into your engine all of a sudden it gives you, the driver full control over adding power output from the engine as you step on the accelerator.
