"eeeeee" noise when hitting 3k rpm
Since i've replaced all the vacuum hoses earlier last year, i've been getting a "eeeeeee" noise at about 3k rpm. I am not leaking boost according to my boost gauge and the car doesn't feel like it's losing boost.
I remember seeing a thread that this noise could come from the turbo itself when the propeller shaft is having too much play...could that be the problem or is there something I should also look into?
thanks.

if it sounds like a sharp beeeeeeee~ noise when you start to boost... my guess would be boost leak from your intake elbow if you removed it during your hose job. take it out and butter up some gasket silicon on top of the rubber ring and reinstall it. see if that helps
if its not a major problem. most likely that's it. happened to me several times. after applying liquid gasket and re-install, its gone

yeah.. i have the greddy elbow too, if anything greddy elbow's worse because it doesn't use the rubber o-ring at all. still need to apply gasket sealer all around everytime i remove it.
when it happens to me, i still get perfect boost pattern, just annoying. almost sound like you hit some kind of warning. its a very minor leak that's why the sound is so high pitch.
try it. imo... its a big possibility, if you still hear it after that... umm...
