[QUOTE=BN;1513066]Ooops. I proofread my writup (#22) but I should have done it twice.
" A lightened flywheel would lower the critical RPMs, probably a lot"
Should read, " A lightened flywheel would RAISE the critical RPMs, probably a lot".[/QUOTE]

That is exactly what I discovered with my dyno and actual driving tests in March of 2013. I had a difficult time detecting the vibrations when the engine and flywheel/damper variations were on the dyno during the tests. In the car, the results were much easier to "feel".
