GReddy Type-S Blow Off Valve
Created to be the most reliable blow off valve system available, the new GReddy Type-S state-of-the art design allows for greater performance in a compact size. GReddy Blow Off Valves are easily adjustable to eliminate compressor surge and preventing premature boost leakage, while increasing boost response between shifts. Each valve is made of durable cast and billet aluminum frame and the valve to diaphragm ratio provides performance that cheap piston types cannot offer. The spring stiffness adjustment screw give the GReddy user the option to match vehicles with mild upgrades to heavily tuned engines. There are many factors in matching a blow-off valve to an application, valve location, turbocharger size and pressure, but as a general rule of thumb, we recommend the Type-S for 100-400hp.
