Not sure how you guys are still driving these things around like that. The compressor wheel is slowly coming apart and all those peices of material are eventualy making their way back into your engine's cylinders.

it's only a matter of time before the motor looses compression if don't address the issue
not true, That's more of a howl vs a whine. Mine is from having fully closed wastegates at idle/low rpms. When logging, I make 3 psi at like 1200 rpm, that's what the noise is from. Open element filters only make it louder. With the stock airbox it just sounds like normal turbo spool, but at low rpms. With open element filters is when it's loud
