GReddy Mazdaspeed3 Blow Off Valves are easily adjustable to eliminate compressor surge and preventing premature boost leakage, while increasing boost response between shifts. Each blow off 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 and the three different sizes 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 RS blow off valve for 100-400hp, Type Rblow off valve for 260-450hp and the Stiff Spring Type R blow off valve for over 400hp applications. GReddy blow off valve is available in easy to install kit form for many turbocharged vehicles.
