hi, i ve been bouncing this round the tt forum for a bit now , but no body seems to be able to help. so i thought i would try here.. problem is a noise coming from the turbo area when the car is at max boost (24psi)ive had it on a rolling road even had a hand down to try a feel for leeking boost etc. but nothin . the noise is a cross between a fan belt sliping and a the top of a bottle been blown and only does this noise when i floor it early and leave it to build up ,lets say from 40mph in 4 gear, ive had a boost gauge on , and it does it at about 22 to 24 psi . got new dv and samco inlet hose fitted, checked all jubilee clips etc, so the question is really what could make this noise without there being a leek?
