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...
Wow, after reading some of these dyno numbers I definetly got shafted from GM!! My 2003 ZO6 with a BLACKWING AIR INTAKE, MODIFIED THROTTLE BODY AND an X PIPE DYNOED AT 353RWHP and 372 RWTQ.

no, thats my point..all yrs vary some and 20 hp is not that big a deal..any car can be 15-20 hp dif..a good set of rear tires on a Z, can make even more difference
Finally got it on the dyno yesterday. 02 Z06. Only mod is a Fram Air Hog filter and the stock air cover cut open more. After the baseline run I had it tuned.
Basline Run:
------------
Max Power: 354.9
Max Torque: 325.0
Final Run after 3 setting adjustments:
-----------
Max Power: 366.8
Max Torque: 354.8
HP Gain: 12.1
Torque Gain: 29.8
Biggest problem on stock was A/F ratios were off. Way off in the upper rpm range and it was running too rich.
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.
