Turbo Problems
OK i just bought a 92 eagle talon tsi fwd.. and about at 4500 rpm i hear a air rushing noise and it sounds like the turbo blowing air somewhere besides into the motor. and it doesn't misfire or anything so i don't think it is a boost leak. i also checked all of the intercooler hoses and they are not broke i even replaced them and still does the same thing.. it is a stock td05h turbo and the only thing that is not really stock is the bov..sorry if i did not make the problem clear enough.

Re: Turbo Problems
congrats on your first...anyways more info is always good, but from what you say its doing, or sounding like cant be anything else but a boost leak. if you cant find where air is comming out, how can you assume it is without symptoms. it could be air leaking out of the seal in your turbo, but your car would run a little sluggish. if you want to eliminate the possibility of boost leak, get or make a tester (hose, pvc cap, valve stem), use soapy water and spray every part of the intake and force about 15 psi into it with a compressor. ive spent the past 3 weeks doing the same thing, and its not that hard except making the tester air tight. give us some more info.

Re: Turbo Problems
I dont think a boost leak is his problem, because he said he runs fine, but my car had the same problem (air rushing sound) and it turned out to be the preload on my wastegate. Look into that, most probably thats is the problem.

Re: Turbo Problems
honestly it doesnt sound like a problem ive ever heard of. about the only thing you can do is watch a boost gauge for unusual drops or increases. the wastegate could be the start of the problem. it shouldnt be a problem unless there is a power loss or excess fuel consumption. air will whistle as it is compressed and forced into a small area.

Re: Turbo Problems
if it was the waste gate, is there any way of testing it? i try to move it with my hand and it wont move at all... or would a new turbo help?

Re: Turbo Problems
