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
