A blow off valve, or as its more commonly know ‘dump valve’, is in fact a pneumatic pressure release valve that releases air pressure caused by the turbo/super charger once the throttle butterfly is shut. This stops pressurised air returning to the turbo and stalling the compressor wheel (compressor surge).
A blow off valve (dump valve) is a separate part and is plumbed in between the intake manifold and the turbo.
Blow off valves contains a spring inside to keep it shut at idle and low boost - please contact us for further info and/or if your blow off valve is leaking at idle.
