no prob....
I have found out tho that for before/after dyno numbers... I will have to dyno ... install... then drive for a couple hundred miles and dyno again...per UR.

Thanks for doing this - before/after dynos. Any risks related to going with the lighter pulley? Seems to me I read a thread or two a while back on my350Z that mentioned something to the effect that our engines components are perfectly balanced... and doing something like this throws that balance off which could result in internal damage long term.

Yeah, there was a huge debate on g35driver about pulleys. Some interesting points here: http://g35driver.com/forums/reviews/...ht-pulley.html . Hopefully, we'll see some solid gains with the Stillen pulley.

This I don't understand. Why would you need to drive a couple hundred miles to see a gain? The only way this would be is if a management system needs to adjust to the new pulley. The ECU can be reset so that is not the problem. I wonder if another control unit needs to adjust for there to be gains.

yeah, in my mind, the most result you would see would be from immediately flooring the car right after first ignition after the install BEFORE the ECU does anything to counteract it.
