BLITZ SUPER SOUND BLOW OFF VALVE
When the boost is increased on a modified turbo car, the standard dump valve usually cannot cope with the extra air it has to release when the throttle is shut. This can lead to permanent damage to the turbo as the air is forced back through the inlet blades. BLITZ performance piston-type blow off valves are designed for modified engines up to 750 BHP.
These blow off valves are designed to improve the response of the turbo and are made from polished aluminium with a brass piston. Boost pressures of over 2 bar are dealt with without any effort, and the resulting sound is similar to the current breed of Group 'A' turbo rally cars.
Blitz are the only manufacturers to include two different types of trumpets with your kit so you can change the sound your dump valve makes!
