Product Specification
BrandGReddy

Installing a high quality GReddy Blowoff Valve is a necessary performance upgrade to gain precision control of the turbo boost process for higher horsepower performance. Blowoff valves are used to prevent compressor surge, a phenomenon that occurs when reducing the throttle of a turbocharged car (with a non-existent or faulty bypass valve). When the throttle plate on a turbocharged engine closes the high pressure in the intake system has nowhere to go and creates a pressure wave. This pressure wave force travels back to the compressor wheel causing a rapid decrease in RPM and possibly stalling the turbo. You will notice a fluttering air sound and when applying throttle a significant lag in boost response. Some blowoff valves are adjustable giving you more precise control of boost process. For higher horsepower performance boost response and precision boost control a blowoff valve is a must for those who demand highest possible precision performance.

GReddy Blowoff Valves are easy to adjust, help eliminate compressor surge, preventing premature boost leakage, and increase boost response time. Each blowoff valve is made with quality materials, durable cast and billet aluminum frame and the valve to diaphragm ratio provides a level of performance that cheap piston types cannot offer. The spring stiffness adjustment screw and the three different sizes gives the user the option to match vehicles with mild upgrades to wild highly tuned horsepower performance engines. There are many optional  factors to matching a blowoff valve to an application such as valve location, turbocharger size and pressure. But as a general guideline, we recommend the Type RS for 100-400hp, these are also available in easy to install kit form for many turbocharged vehicles. Precision boost control of a turbocharger will help boost response time and improve overall performance from mild to wild horsepower gains.
