Sounds like a raspy grinding. The car idles fine but when I rev it up that noise is so loud and makes the car vibrate. I need your help.

i cant view the vids since im at work but a raspy grinding could be play in the turbo.. pull off your intake and check for shaft play

edit: i missed the "so loud and makes the car vibrate" part. shaft play wouldent do that ...

no its not the turbo

failing/loose pulley such as tensioner and idler. debris hitting the crankpulley(harmonic balancer) could be the balalce shafts. but it sounds as if some think is in your exhaust. I'd do a compression test after a good eye survey... what have you checked already?

 

[RonRonTSI]

Sounds like its in the timing cover. im going to pull it tom. ill keep you updated

 

[jamerican01]

yeah i assumed so.... good luck.

I'm unfortunately not somewhere where I can listen to or watch those vids, but do you happen to run a heat barrier gasket on the intake side? If you don't have your EGR port blocked off in the exhaust runners hot gasses from anti-lag can go into the EGR system and melt those gaskets, causing an exhaust leak in your engine bay. Just a thought.
