The Blow-Off valve (BOV) is a pressure relief device on the intake tract to prevent the turbo's compressor from going into surge. When the throttle is closed rapidly, the airflow is quickly reduced, causing flow instability and pressure fluctuations. Surge can eventually lead to thrust bearing failure due to the high loads associated with it.
Blow-Off valves use a combination of manifold pressure signal and spring force to detect when the throttle is closed. When the throttle is closed rapidly, the BOV vents boost in the intake tract to atmosphere to relieve the pressure, helping to eliminate surge.
High-Quality diaphragm and short stroke significantly increase response.
Dual spring system promoted response and allows for high boost pressures.
Hard-anodized valve for increased air flow.
50mm flange diameter; Holds up to 35PSI boost pressure.
Draws in surrounding air and releases aggressive unique discharge sound.
