anyone know how to ajust a bailey dv12 dump valve
 

i've got a bailey dv12 dump valve but you can only hear it at 6,000 revs each gear can you adjust this somehow i've got a wrx sti 2002 prodrive with ppp

they are not adjustable, is it new, second hand? could need a clean?

also what boost are you running?

its new not sure how to adjust the boost :S

you can't mate :(

there not a very loud dv so im sure its working ok or you would be getting turbo stall like i do, and trust me you'd hear that.

non adjustable mate . may be sticking or not fitted properly

ye as above mate, may be sticking. I start to hear mine about 3k I think only quiet mind until high revs. I like that though. Steady driving-low noise. Hard driving-loud noise!

have a look arond the pipes and fittings for splits etc

i have a dv10 second hand just fitted and never tightened a bolt correectly
soon as i did that worked fine
also check there aint nowt clogging it up!
