Turbo lag is the enemy of any turbocharged vehicle. Greddy's Blow Off Valves are easily adjustable to prevent both premature boost leakage and compressor surge. Each is made of durable cast and billet aluminum frame, and the valve to diaphram ratio provide preformance that cheep piston types can not offer. The spring stiffness adjustment screw and the two different sizes give the GReddy user the option to match vehicles with mild upgrades to heavily tuned engines. The Type RZ blow off valve is a 40 mm valve and reccomended for applications up to 400 horsepower. This is a universal blow-off valve, vehicle-specific kits are available for most Japanese cars.
