Nissan 370Z Forum - View Single Post - Thoughts on Engine Sound at High RPM's (kinda long)

Just finished my BSME, haha. Wanted to explain it a little more in depth to provoke thoughts of others on the board.

I would love to test it out, but just dont have the time to do it. However, I would be interested in hearing some feedback from others who may have used a light weight flywheel option (not sure if anyone is doing this with their 370's).

If it can be confirmed that a lighter flywheel causes the problem to get worse, than it stands to reason that using a heavier flywheel (one way to overbalance an engine) would reduce vibration and sound.
