My dyno #'s
I just got my 03 EB Z06 last week and this is my first post here. It is stock and has 3,000 miles on it. I figured before I started doing stuff to it I would get a stock dyno since I never did that with my TA. I’m not sure what these things usually dyno at but I’m pretty happy with it. Overall I’m amazed at how the car feels compared to the TA. I just wish now I would have bought a vette sooner.

Ain't dyno #'s grand. The uninformed get real excited when those non corrected numbers show up, then wonder why they're getting their as--es handed to them by cars with "less" HP. Oh well.

We did back to back runs. The first run was after the car sat for about 40 min then we started the runs. As the car got warmer it did better.
Actual numbers do not compensate for anything, and therefore are generally higher than what a car is realistically making.

It depends on what the ambient conditions are. If you dyno on a 100 degree F day your actuals will probably be lower than SAE. If you dyno on a 30 degree day your actuals will probably be higher than SAE. BARO and humidity are also factors in the equation.
SAE levels the playing field. It is impossible to compare an actual run done on Monday with an SAE run done on Tuesday at a different location.

Thank you for clearing that up. I didn’t realize the numbers could be corrected in different ways. I'll ask them if I can get a SAE printout so it will be a little more accurate. Nonetheless I'm still happy with the car. The temperature was 70 when I dynoed but I'm not sure about the other conditions.

That is damn funny!!! Nut kick!!! Seriously, good numbers for a stock car. The un-corrected numbers give you IMO what your car is putting down that day, in those conditions. The SAE is a better comparision for location, dynos ect... I have been educated on this board for SAE vs uncorected numbers, and I have seen a delta of 50HP on 3 Dynos, in very close conditions with in 5 days. Great coments and explanitions of SAE as well and there are so many experiance, very smart folks here (and great guys who always are willing to help us out) Congrats and welcome aboard!!! Damn I love that south park style kick
How about some pics or your car??? Take care!

Standard Atmospheric conditions are defined as; altimeter 29.92, temperature 59 degrees farenheit, and at Sea Level.
Do atmospheric conditions make a real difference? Well, before I lost the Triumph sprint I could wheelie easily with a simple throttle roll-on in first gear if the temp was below 40 degrees. Above 70 degrees it would seem like the bike lost 10HP.

Internet dyno comparisons are a bit of an excercise in futility anyway - there is more variance between dyno's and dyno operators than actual differences in (stock) cars. SAE is a way to somwhat normalize the comparisons. It is good that you got a baseline, I would ask the guy to SAE correct to compensate for local weather changes (like humidity etc) and use the baseline as a tuning aid as you add mods. Les

All you have to do is have your operator print off the SAE corrected chart - it is in the computer.
