fitted a new d/valve and now its not boosting as high

[jay26]

right just fitted a new forge 007p dv as the bailys one that was on it was leaking and now my boost gauge is reading about 5 psi lower it use to boost to 16 psi then drop and hold at 15 psi but now it seems to boost up to about 12-13 psi and hold ther

is this becouse it dont have to compensate for the leaking one or something like that

anyone know for sure what it is

Is it all conneted tight not leaking anywhere. What spring did u have in the bailey one.? have u fitted it the right way. I Read a thread earlier about the springs and d/v and fitting the 007p backwards and having to counter the boost with a stronger spring.

cant be that its so obvious to fit lol will check for leaks soon as i fin work

whats the spec of the car?

yellow spring in the forge is more than adequate

When I had a leak on my DV hose the boost was peaking at 27psi (instead of 21psi), so as you can imagine I was $h1tting myself until it was sorted (Stage 2 LCR). I would say it was the leaky valve that was causing your excessive figure.

no mate mine was lower than it should be ive serviced the balieys one and put it back and its fine again

 

[jay26]

any one know (for referance now)

green or yellow springs for forge 007. if it has a yellow fitted it may be to stiff so may be worth dropping to the softer green 1
