With that being said, my understanding of torsional vibration leads me to believe that dampening this kind of vibration will be fairly straightforward--you take something that will absorbe the energy, like a fluid or a "spring" type solid like rubber, and stick it on the thing you want to dampen. Do you have any logical reason to suggest otherwise? If not, stop posting. I'm not saying I have proof, but most of us understands how vibrations and dampening works, I hope.

There is NO WAY our OEM pulley will have better dampening characteristics than the ATI dampner, even if it's made for a GT-R. Have you seen the little rubber ring? Lol

Please, guys, if you're not here to help with the original question, and are going to attack my reasoning, at least come with facts and logic.
