FLYWHEELS????

**quattro16** · 10-19-2008 04:23 PM

Well lets start that I have noticed a horrible vibration right at 3800 rpms that is there with the clutch disengaged and engaged ( Louder). The vibration makes the car 10 times louder inside and vibrates the center console right at that rpm and is fine at all other times. I really belive its the flywheel. I have the southbend stage 4 ofe clutch with about 2500 miles now. Just wanted to see what all you BT guys are using and how you like them? TIA

Plenty people running the 15 lbs flywheels. SB even makes a 20 lbs billet steel flywheel. They also sell the disk only if you are looking to go from a stock flywheel to a lwfw.

check the harmonic balancer on the front of the motor

No problems with chatter?

tips how?

I'm getting a big vibration usually at lower rpms though. Idle/revving above 3-3.5k is fine.

The lighter the flywheel the higher amount of chatter. SB claims their 20-21 lbs billet steel flywheel to have zero chatter, that is what Andy told me directly.
