The Forge Blow off Valve for the mini cooper S has been designed to act as a safe replacement for any mini that operates under increased stresses and strains resulting in higher operation temperatures especially if the ECU software has been modified allowing increased boost pressures.

BLOW OFF VALVE VERSION - You can hear the dumping of the air

RECIRCULATION VALVE VERSION  - You can not hear the dumping of air


Many stock OEM R56 mini blow off valves fail as a result of split diaphragms where the valve will not open fully if at all, resulting in power loss and poor throttle response. Often when the Valve fails the engine management light doesn't come on to inform you that the blow off valve has failed as there is still pressure at the valve. 

Heavily modified minis or BMW minis subjected the hotter environments often suffer from blow off valve failure due to the cooling and contracting of the stock OEM plastic, used to construct the valve. The more heat the cooper s valve is subjected to the greater the likelihood that it will fail as the plastic becomes brittle.


In serious cases the brittle blow off valve housing can snap off and enter the turbo, causing it to become damaged destroying the turbo. The Forge Cooper S blow off valve is a complete engineered solution that eliminates all of the mentioned problems. The Valve is constructed from aluminium and unlike the stock mini valve, it use's a tried and tested piston solution. The solenoid which activates the piston operates using a simple plug and play connection allowing for easy installation.

The forge valve allows a series of interchangeable springs to be used allowing the user to choose the required spring dependent on the boost requirements of the car.
