HKS compressor blowoff and bypass valves play a vital role in any turbo system because they not only improve the performance of your vehicle but they also increase the longevity of the turbocharger as well. The primary function of any blow-off or by-pass valve is to prevent compressor surge by relieving the compressed airflow that reverses direction as the throttle is closed. HKS blowoff and bypass valves reroute the pressurized air, that is normally forced backwards into the turbo compressor, into the intake stream or by venting it to the atmosphere. Subsequently, engine performance is then increased from quicker turbo spool up, as the compressor speed is not reduced by the backward airflow. The longevity of the turbo is also increased, as its bearings will not suffer from the impact that is also produced by compressor surge.
