The Super Sequential Blow-Off Valve (SSQV) is a pull type relief valve. The SSQV is
actuated by pressure alterations only, ensuring quick valve response and complete
closure during idle. Typical blow-off valves utilize large valves in order to accommodate
high boost/high hp applications. However, these large valves react slowly and require
high activation pressure to open. Smaller, fast reacting valves, do not permit the air flow
required for high horsepower. The SSQV incorporates both for maximum performance.
It is engineered utilizing a small primary valve and a secondary valve for additional relief
capacity. The SSQV is made of billet aluminum and emits a unique aggressive sound
If the throttle plate is closed while engine is making boost, the compressed air will return to the
compressor housing which causes "compressor surge" and also damages the turbine shaft. In
the same condition, the GReddy Blow Off Valve will release the compressed air from the charge
pipe to protect the turbocharger from the pressure spike and also gives quicker boost recovery.
By modifying the vaccum line routing, it can also be used as a Relief Valve.
