ok guys I have an internally balanced MMR pro mod 900 engine and I am having a bad vibration! The vibration gets worse as my rpms increases or if I free rev it in neutral so that rules out anything from the transmission back. I have a steeda underdrive harmonic balancer/pully on the front then out back i have a fidanza aluminum flywheel with an MMR clutch. So what do you guys think it is? As i hit about 4k rpms the engine feels like its ready to rip my car apart peice by peice. So what do you guys think could be causing this? The Flywheel is a 0 balance flywheel due to the engine being internally balanced. Could it by the clutch, flywheel or balancer? Help me please!!! i gotta get this fixed up...thanks guys

I think you need to give MMR a call. Let them know whats going on and tell them what you have done and see what they tell you.

When I had my clutch replaced I think the shop screwed up after resurfacing the flywheel and forgot to replace the dowels that line up the pressure plate. I had a monsterous vibration, so bad I didn't even rev it over 2000 because even just off idle it was really bad.

Took it back, they re-re'd the clutch and it's been fine ever since.

First,stop driving the car! You're killing the bearings! Next,I'd say that you either have the wrong flywheel for the car(maybe sent you a 28 oz one) or like trinity said,your clutch package is out of alignment.
