Collection: Blow Off Valves
A blow off valve, also known as a bypass valve or diverter valve, is an important component of a turbocharged or supercharged engine's intake system. Its primary function is to release excess boost pressure that builds up when the throttle is closed, such as during gear changes or deceleration. When the throttle closes, the turbocharger or supercharger continues to spin, compressing air & creating pressure. Without a blow off valve, this excess pressure could potentially damage the turbocharger or cause other issues. The blow off valve operates by diverting the compressed air back into the intake system, downstream of the turbocharger or supercharger, rather than sending it back through the compressor. This action creates the characteristic sound often associated with blow off valves. Blow off valves come in various designs, including atmospheric (vented to the atmosphere) & recirculating (redirecting the air back into the intake system). The choice depends on factors such as performance goals, emissions regulations, & personal preference. Proper selection & installation of a blow off valve are crucial to maintain the reliability & performance of the engine, as well as to achieve the desired sound & response characteristics.
