Evolution MotorSports has engineered a new performance and maintenance component for the Porsche 997 Twin Turbo. The EVOMS 997TT Boost Recirculation Valve is a direct replacement for the OEM unit and features an improved and more efficient design. Their BRV is CNC machined from 6061-T6 aluminum, hard anodized and utilizes military spec Viton™ O-rings. Their CAD designed BRV employs the same operating principal from their 996TT piston diverter valve which has been successfully operating for nearly 8 years. In real world testing, the EVOMS 997TT BRV eliminates issues of boost leaks and diaphragm sticking and deterioration that is consistent with the OEM valve in higher than stock horsepower applications.
