[Supras] Lightweight flywheel+balancing

[Rich Peacock]

That procedure is similar to what I use to balance the blades on my RC 
helicopters.

Run the engine at the speed where the vibration is worst to get an idea of the vibration magnitude.  Then take the access cover off the bell housing, take out one pressure plate bolt, put a couple of washers under it, and reinstall it.  Run the engine again, and see if the vibration has gotten worse or better.  Try this with each of the pressure plate bolts in sequence until you find the one or two at which the vibration is minimized.  Then change the number of washers to obtain minimum vibration.  That worked like a charm.  At one time I believe I saw a GM bulletin describing the same procedure for balancing a Buick flex plate and torque convertor.
