Out of curiousity, is this the same Z1 Auto that is spoken about here: Z1 Auto in NY - Page 8 - MY350Z.COM Forums
Doesn't sound similar to that thread!

Good look-out, Sam. Car put down 493whp on the stage 2 kit. It runs like a raped ape at wide open, but is very tame when driving normally. I'm sorry I can't give everyone a specific power output on the drive-shaft alone. It was kind of a last minute decision to throw the Z1 on there.
I can at least say I haven't heard any unwanted sounds; no humming, whining, popping whatsoever.

Nice numbers, But what PSI are you seeing , I know there has been much debate on GTM and Still but at 9 PSI I'm See 412 WHP and 300 WHTRQ, Just hard to imagine seeing another 80 WHP and 65 WTRQ on 2 PSI?( STG 2 is 11 PSI on Stillen). Numbers I have seen with that are lie 434 WHP and 325 WTRQ or so. Thanx man

Full disclosure. No before or after dyno. I also have a lightweight flywheel. bI just installed the aluminum driveshaft I got from a forum member who is de-modding. I took it for a test drive. Initial impression is good.
First of all, I could not hear any significant additional noise. However I must preface that by saying that I have the Motordyne E370 so it would have to make a lot of noise to be noticeable over the exhaust. I thought I hear the slightest noise when in first and 2nd gear at high RPM but as I said it was extremely slight and I had to strain to hear it over the exhaust. No vibration, No hum.
OEM weighed 31 lbs, Z1 aluminum 1 pc weights 16.4. Install was easy, fit was perfect. What I can feel is faster revving especially toward the middle to top of the RPM range. The RPMs also fall equally as fast when I disengage a gear. Downshifting seemed easier and smoother.
Overall impression - positive. However this is an initial feeling based on only a test drive. I will wait a few weeks until I have had more seat time with it to make a full determination.
