Our GP dump valves relieve compressor pressure surge caused by changing gears or backing off the throttle quickly. This valve is an extremely important part of any turbo system allowing quicker turbo spool up between gear changes and greatly increasing the life of the turbocharger.
How's about this for the daddy of all dump valves? As Dan White said on seeing it, "it looks like the Mr Space Station, just a bit smaller, and more gold". This monster dump valve is made by GP Racing who have a hand in the Jap Touring car scene, it's also Group A and N approved and is an ideal fitment for any big power turbo car. The spring tension is adjustable which in turn affects the volume of its whoosh. The trumpets help direct the sound to where you want it and it looks the tits finished in gold.
