Loud Screech New Recirc Valve
Just wondering if anyone has come across this issue, it's a little hard to diagnose when I am driving. It doesn't sound like turbo stutter, though I guess it could be. I just put a new recirc valve on (moving from vta), and adjusted it to where it barely breathes at idle, and releases perfectly fine at part throttle with zero stutter at low boost, however when I really wind it up 20lbish, I get a loud almost un nerving squelch. Not really sure how else to describe it, I used bending radiator hose for the return (has a spring inside), and it returns to a Perrin turbo inlet. I am wondering if the sound I am hearing is the pressure making it's way through the tube? Or possibly hitting the turbo on the intake side?(the pressure). I have checked the obvious signs, kinks in the recirc line etc, but the path to the turbo inlet from my bov is a fairly bendy one.
Again just hoping someone may have stumbled across a similar issue.
