Weird *** noise, coming from the left front

[burntricer]

so my car has been running GREAT for the past month! yesterday i was drivin around boosted to 7 like normal and i got this god awful noise, almost like a moracca(sp?) and LOUD, coming from the left front somewhere...and ONLY the left front.

it did it every time i went over 5psi of boost, but intermittently, not every time i boosted. so i did some investigating today, checked for exhaust leaks, nothing, checked suspension parts thinking maybe wheel bearing? but they all came out good...so i did some driving tests, if i keep it out of boost and accelerate to highway speeds, hitting the limiter in some gears, it doesnt make the noise, but as soon as it hit 5lbs, it screamed at me.

so i started thinking turbo, but i pulled my mafs pipe, and there is next to no shaft play in the turbo, no oil in the charge pipes, and it still boosts hard and fast like normal.

i checked the bolts to the turbine inlet and the gasket, its all good, im really lost here people...it kinda scares me its so loud.

the other thing im thinking. i have a greddy type S BOV not hooked up, but on a flange on my charge pipe, it was running, but it was causing too much stalling issues so i put my stock recirc valve back on, could it be opening? causing the air to piss out?

what stumps me, is it hasnt changed in performance, it hasnt been burning more gas, or oil, its not affected drivability... anyone got anything for an idea?

thanks for the help nico.

anyway i got it fixed, it turns out it was the turbo to manifold bolts.
