What is a blow off valve?

A blowoff valve (BOV), dump valve or compressor bypass valve (CBV)is a pressure release system present in most turbocharged engines.Its purpose is to prevent compressor surge, and reduce wear on theturbocharger and engine. These valves relieve the damaging effectsof compressor "surge loading" by allowing the compressed air tovent to the atmosphere (BOV case), making a distinct hissing sound,or recirculate into the intake upstream of the compressor inlet(CBV case).

How does the blow off valve work?

A blowoff valve is connected by a vacuum hose to the intakemanifold after the throttle plate. When the throttle is closed, therelative manifold pressure drops below atmospheric pressure and theresulting pressure differential operates the blowoff valve'spiston. The excess pressure from the turbocharger is then ventedinto the atmosphere or recirculated into the intake upstream of thecompressor inlet.
