not sure what this noise is, but i just had my s/c installed over a month ago (9.5 psi) its a daily driver had no issues from the start, now this week when i am boosting around 5200 to redline i hear a noise like a blowing or rubbing noise, engine sounds strong and the boost stays steady around 9psi but i dont feel like im going any faster at that point, this happens in every gear if im getting on it, but when im just half throttle it doesnt happen, im a F/I newbie, is the stock clutch taking a dump (not grabbing)? never blew a clutch before dont know any signs of it either, i read other clutch problem threads and they all say you hear grinding which there is none in my situation, i was prepared to upgrade my clutch in the future, just dont know if this is the problem yet, any ideas or suggestions for me to test what is wrong, my vac is steady and has no boost leaks, didnt think 9.5psi would crap out the stock clutch in a month

 

have you upgraded the bypass valve? maybe its leaking there

 

its a forge 007

 

hmm. can you post a video?

 

u would need to hear it, its weird cause i can sit at a stand still and rev all the way to redline and hit 9psi and the noise never happens, but while driving it happens very odd, because the only difference is the transmission is in the mix while in gear so a clutch should be the culprit
