My car kind of sounds like (from what I remember). Not as high pitched, but that could be from a few different things. Have you logged/monitored the car? Does everything check out?
Sounds like a leak to me. What kind of boost are you pushing? I have heard some of the IC gaskets blowing out around 20 psi. Do you have a boost guage?
How about your BOV, did you get a good seal around that when it was mounted? I would check all the clamps and what not. Looks like you have a FMIC so it may be the gasket at the turbo or a clamped joint.
I have a K&N Tyhpoon and the turbo sounds nothing like that....
So did you ever figure out what it was making the sound?....I know its a old thread but my buddys car is doing the same thing and I was just curious to hear what you found out with yours.
Seriously that sounds more like the transmission. I've only heard that when the car has been run really hard and the transmission oil is heated up. I would also have that checked or check it myself. I would completely steer you to the drivetrain though.
