im just asking a question thats has bugged me for ages!!

bascially you get sum turbo cars with dumpvalves that go raaa Tishhh
and other that go zzzz pistttt sorry for the example noises but its hard to explain in writing!

anyways moving on anybody know what makes this difference is it the different type of DV or is the amount of boost that your running?

hope you can inlightern me on this subject

maybe difference between piston dv and diaphragm dv. more of a whooosh from diaphragm and a ptssss from piston.

 

sounds like ya on to somethink there chap!!

Will both these fit onto a fiesta turbo sorry if i sound like a nail but its one thing im not clued up with

cheers

 

Yes they will both fit but to be honest I wouldn't bother unless you reall want the bus brakes sound

 

OMG thats has just brought back memories of someone explaining to me about dump valve noises
