How it works

Blow-Off Valves eliminate compressor surge when changing gears. Excessive back pressure is created when the throttle is closed during gear changes or deceleration, causing turbo cavitation. This is detrimental to the life of the turbocharger. Fitting a BOV will substantially improve this problem. Installing a BOV will also significantly reduce turbo spool-up time. A substantial improvement in response from the turbo between gearshifts and a quicker boost delivery will result in an increase in torque at lower RPM.
