82z96ss,
First let me say --Very nice car!
I would also do what Charley asked--check your codes

I was listening to your run --when you first took off car pulled hard and it sounded like you went right up to red line and hit it just right you were ahead at this pt. but it didn't sound like you went to redline on the next shift it sounded like you shifted out a little early and the rpm's dropped a little out of power range--you were along side of each other maybe as he juiced it you saw him thru the corner of your eye creeping up, and you shifted a bit early ,instead of bringing her to peak, so your next shift wouldn't have had to struggle to recover--if so I think you would have held him off---Like I said very nice car--just giving some input for the next time and just an observation---JoeG [img]/ubbthreads/images/graemlins/beers.gif[/img]

Thanks for the suggestion Joe, but tell you the truth I shifted right were I wanted too. BUT I didn't realize until at the dyno today were my rev limiter is. I shifted around 6200 but now I know I still had 300 or 400 rpm left in her.
Man, wish I could do a rematch, but losers always want the rematch. [img]/ubbthreads/images/graemlins/rolleyes.gif[/img]

I thought 6200 was high. WOW was I wrong. I'll get em next time. [img]/ubbthreads/images/graemlins/[/img]

82z96ss:

At what RPM did the car hit peak HP at? Also, what did it look like right above/below the peak? The reason I ask is, that I was shifting our car at it's HP peak, until Pete suggested I spin it a little tighter. I did, and it went quicker. So, I shift about 500 rpm PAST the peak. BUT, my peak was fairly "flat" for a peak, as I was within 10hp of my peak (425hp) for several hundred rpm's. I peaked at 5800, but shift at 6300 when it nosedives, and it goes quicker. Might be something to look into...

I think the codes are definitely something I'd look into if I were you. Before you posted your dyno #s, I was gonna guess the RWHP of the Z-28 on spray you ran at around 425rwhp, assuming he has the usual free mods and probably a couple of other add ons. Then, your dyno confirmed that I wasn't too far off, since you 2 ran so close. I'm not an expert on the '02 ZL-1s, but I'm gonna guess your Phase III should be in the 500rwhp neighborhood...? Charley?

Just got back from a car show and saw #58. Very nice phase III painted in evening orchid.
