How I understand it is this. Sound can shatter glass at the right frequency and db level. Each time the piston is on its power stroke it flexes the crankshaft and then the crankshaft reverts back to its original state. At 6000 rpm, that would be 100 hertz, or 100 times a second. Its a low frequency but the load is pretty high. The crankshaft will shatter or split/crack at its tuned frequency, just like a glass. Now fill the glass with rubber, it will no longer shatter at its tuned frequency. The damper takes those vibrations and eliminates it as heat.

Me, I bought a fluidamper for my 2.4 because I got sick of the stock damper cracking and slipping on my 1g. Id never run an undampend crank.
