Pulley Size/Fitment: Z34 vs. R35

7419sundat

seriously if there was no combustion we wouldn't need a dampner the rotating assembly would only need balanced. If you think it will be better then do it... no one is gonna pull any data to prove you otherwise. Actually you should call fluidampr or somebody and ask them questions about it.

I don't point things out just to be an ***; keep that in mind before judging me for my next comment.

If you are going to attempt to prove/disprove something, 7419, please use logic, and relevant information. YES, if there were no combustion, we wouldn't have this conversation. YES, if the glove didn't fit, Mr. OJ would have had a difficult time getting his hands in the glove. WHAT THE **** DOES IT MATTER to the question at hand?

Very similar means they still have slight differences, and slight differences at 7,500rpm become much bigger differences.

I don't understand theses moot arguments. Are people running around with lightweight pulleys that have NO dampening? Yes. Are there people running their boosted 370Z's with the OEM pulley? Yes. I do not have a sophiscated understanding of the complete mechanics behind torsional vibration; do you? I will assume no. 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.

Ill try to help one last time. Every engine has a different frequency that the dampners is designed for. You need to figure out which one your trying. For instance if a race dampners was designed for 10000 rpm it probably wouldn't be good for your car. A daily driver one would obviously dampen at lower frequencies. Basically what if our engines need dampening at 3000 and redline and the dampners you chose didn't do that extreme vibrations could damage your engine especially the more power you have.

sloboi

Which...is the same RPM range as the GT-R...

No one's attacking you, we are offering our view points. But since you seem to have your mind made up, go ahead and do it. Maybe it'll work, maybe it won't. No one's tried it so why don't you be a first?

I've probably been a bit of an ******* to 7419sundat, so for that, once again, I apologize. Thanks for everyone's input, though! Still no answer...tried contact AMS, and no response, as I predicted.

sloboi

That ******* was "butt-hole".

You guys gave me a head ache but nice thread. I was curious about the Z's dampening. I've ordered an NST Pulley kit and I see your logic with a boosted engine. I had no idea the stock pulley had a rubber ring around it. Now I'm second guessing my NST. Will go SC next year, so I will keep my stock pulley around.

Subscribed, will fallow the thread to see if a supplier is found.. Thanks fellas.
