Mine was at 344 with the mods(see my sig) and before the LS1 Edit. After the LS1 Edit, it pulled a 373! The Edit really made everything come together.
Oh.....by the way, I ran low 12's with lousy shifting! I'm sure that with a better driver that me the car will go 11.8's. I missed gears and didn't launch real well. My 60' times were well into the 2.XX.
my 01 dynoed the same-see the sig..they really aren't that different,01-04's , four yrs of Z, 4 cars and you will probably get 4 different dyno figures...
Those are some really good numbers for a stock car. You've got one of a very few. :jawdrop:
My '04 Z put out 358 rwhp on a Mustang dyno, and I've got Kooks headers hi-flow matrix cats, X-pipe, 160 tstat, Vararam cold air intake, and HP Tuners tune.
On a Dynajet dyno it put out 390 rwhp. with the same mods.
400.25 rwhp after LS1edit on a dynojet, cold morning about 50 degrees. I doubt the actual numbers are accurate, but there was a 20 hp increase from baseline after tuning about 3 hours on the dyno. The tuner squeezed another 20 hp, primarily by leaning out the mixture a bit from 3200-6200 rpm. Stock 03Z.
I have not dynoed my 02 Z when it was stock, but did dyno my 2000 C5 6spd LS1. It put down an amazing best 342 rwhp and I don't remember the tq. I will have to look it up.
A total of 3 pulls.
The guy running the dyno said it was the strongest stock LS1 C5 he seen. I still regret selling the car.
My 03 made 358rwhp bone stock. Added a Haltech stinger and a good solid tune and she put down 380rwhp. The pulls and WOT tunning were done on the same dyno. I believe it put down 367rwhp with just the intake swap. It really came to life after the tune was finished. I have been very pleased with the power of the car. It's time to step it up though. LG headers are next on the list.
