Re: IML: Question about harmonic damper

[sosmi@xxxxxxxxxxx]

Rob thats quite true, but the race engine has engine harmonics that the normal engine will never see. The damper really helps to take the sudden shocks of combustion, and take some of the natural vibrations of the engine, and dampen them, this prevents crankshaft breakage, and prolongs bearing life. After all that, the stock damper is all you need.I'm having a nice day thanks, Dave.
