right i got a forge dump valve which was failing to dump, looked on the forge website and they supply a spring kit for the dv the blue spring is for 23-30psi... so took the dv apart to find it has the blue spring which i guessed was the problem of it not dumping away as my car doesnt boost this high!!
so i have brought this spring kit got it today it comes with
green spring 5-15psi
yellow spring 15-23psi
blue spring 23-30 psi
red spring 30+psi
i thought the green spring would be the one to use so tryed this and the car would dump away like mad very easily at just a touch of the throttle but would show a reading on the boost guage of not going over 0psi :-| and lost alot of power so i guess that means its leaking?
so tryed the next spring the yellow one 15-23psi it was still dumping away not as easy as the spring before but was still only reading around 8psi so does this mean its still leaking?
but how can it when it says this spring is good for 15-23psi
oh and the next spring is the blue one which is 23-30psi and was failing to dump
the spring kit also comes with little spacers what you use.. which say in my case the blue spring was to hard but the yellow to soft, you insert these little spacers which incease the tension by small amounts! but these didnt seem to do anything!
