I have just ordered a Black Evo VI GSR with Stage 1 from Ralliart and have seen details of dump valves!

What do they do?

Thanks

Simply put, when you lift off the throttle the dump the built up boost pressure that suddenly has no-where to go. Most oem valves are of the recirculating type i.e. they dump into the exhaust and are pretty quiet. Aftermarket jobbies vent to atmosphere and are considered desirable due to the loud PSHHHHT! sound they make.

You can go here if you want a more detailed information on turbo components and their functions.

You meant to say they recirculate back into the intake.

 

[Guest]

Yes. Sorry, intake it is!

Give the boys at Forge Motorsport a call on 01452 380999
They do a couple of valves for the Evo that look and work really good.
Or I think they may be at TRAX on Sun 10th Sept.
Unfortunatly I wont .
