Turbo guys, need a little help.

[benniev]

I've got video evidence of something going on with my car.

When I'm easing into the throttle, I get no off the wall sound. When I go about half throttle (SR20DET, stock turbo) and get into boost.. It sounds like all hell is breaking loose, like a mixture of bearings grinding and an exhaust leak).. I've checked for shaft play in the turbo, I've tightened clamps and made sure none of my charge pipes are cracked.. Car builds boost just fine regardless of where I set the controller.

Anyone got any ideas on what it is?

Vids are here -- last video is probably the best example.

I'll check the downpipe and whatnot, but when you pop the hood and the engine is at idle, you can rev it and you won't hear any of this at all. It's only when the car is building boost.

And I should note that it doesn't make a peep when you drive and keep it in vacuum.

The gasket between turbo and manifold is done! Change it and you'll be happy again

I take it you've had this issue? Lol

Would it still build boost and not drop off with the gasket leaking??
