A diverter valve, also referred to as a "pop off valve", "blow off valve", "boost re-circulation valve", "air/boost bypass valve" is designed to re-circulate the boost pressure that gets built up in the intake manifold in between shifts. The valve at idle (under vacuum) will remain open allowing the air to circulate freely through the intake to the turbo (s) fresh air side. As soon as the throttle is cracked, i.e.: the accelerator pedal is moved, the valve will be forced shut stopping the re-circulation of intake air to the turbos and allowing all the boost pressure to enter the motor. This non-adjustable valve is designed to be a direct OEM replacement, and includes vacuum hose extension, vacuum hose adapters, and hose clamps. Constructed of a solid aluminum body and brass piston, this valve eliminates common failures with the OEM valves and has large ports for quick response in high boost applications. Boost will come on earlier giving an increase in torque at lower RPM. Also included are two extra springs and two shims for cars using high boost levels. The silver spring is pre-installed and should be applicable for most drivers; it has a spring rate slightly higher than the OE valve and can handle boost levels up to 18psi. The yellow spring is suitable for higher boost chipped applications, 18-22psi. The blue spring is a "race" spring and should only be used in very high boost applications not driven on the street - the high spring tension means the valve only opens for short periods. Compact design does not interfere with engine covers like other valves being sold. Swivel top allows rotation to adjust the hose alignment. Perfect for tight locations as in Audi 2.7T and Porsche Turbo models. Inlet/outlet OD 1.0"/ID .85"

Racing Dynamics is an aftermarket company that started back in the 1980s. The company was initially manufacturing aftermarket performance parts for BMWs. They were then later on acquired by Electrodyne which help them expand their operations worldwide. Today, the company has been developing and manufacturing parts not just for BMWs but other high-performance cars as well like Porsches’ and Mini.
Racing Dynamics offers various parts upgrade such as intake systems, air filters, suspension parts, and other automotive accessories.
These are designed by experienced racing engineers who have their fair share of exposures racing Porsches. They have used those same technologies in their products which help in providing the customers that exhilarating experience.
The company creates some of the finest products in the market since they also use the best materials they could have. They use high-grade metals and composite materials depending on the product they would be manufacturing.
Each part they produce is designed specifically for the vehicle it would be applied to. Every vehicle has its own characteristics. Hence a part specifically made for it would bring out the optimum performance compared to something that is just made for universal application.
Racing Dynamics has created products that have both form and function. They offer a comprehensive list of aftermarket parts ranging from Carbon Fiber air intake ducts to performance-oriented suspension parts. Visit Vivid Racing and check out their list that would fit your specific needs.
