Find noise: Win case of beer: NOISE IS FIXED

[Jeffros Spec V]

So I have this noise. Hardly noticeable at idle, if I blip the throttle (while not in gear) you can hear it wind up and then when the RPM's drop it goes away. Kinda doesn't do it when under load.

I've searched Nasioc for "inlet noise" and "weird noise" and found a bunch of threads with what I think is the same noise but to no conclusions. To be honest it sounds like the ball bearings in the turbo are ****ed but I took it out and no shaft play and it spins nice and smoothly. The noise is coming from the turbo area (or so it seems.) This noise was not occurring until I did turbo inlet, catch can, new front (header) o2 sensor.

I need to figure this out, if you find it I'll buy you a case of beer, your choice (under $30)
