Well it has been 4+ months and 5500 miles but I got my car on the dyno Thursday, bone stock. 340.6 RWHP
I have since installed Corsa Indys and Ram air.
This week I will see what the new mods have done for me.
I have found it best to have my cars dynoed where they are not selling me anything.
I trust the numbers.

Absolutely bone stock? No aftermarket filters, mufflers, etc.?
Also, is it going to be the general concensus that 15% the number to use for driveline loss?
If so then 340.6hp is a good number. It comes to 400hp at the crank!
I hope to put at least 1500 miles on my car before dynoing mine bone-stock as a baseline. Maybe we can get a FAQ sheet showing members dyno numbers and list the mods.
And that was with no one playing with corection factors, etc.
That is with 5500 miles and I break em in hard.
This week I will try to get to the dyno with the new mods. Corsa Indys and Ram Air.
I am doing the mods in stages and taken the car in after each mod.
I am going to keep track of the real numbers, not the mfg.s claims.

Tom: Your dyno numbers appear to be right on if stock.
Frank, I think the cold air numbers (SAE) are more like 350-355rwhp/trq for the Z06s. Exhaust is really about breakeven or less on dynoes here. My numbers were on the conservative R & D Dynojet with a CF of 0.96 and before the oil pump was replaced and with 3000mi. The uncorrected numbers were 369rwhp/trq. The car feels 5hp stronger now with 2k additional miles on it. I will redyno when the DRM stuff is in place.
Those are good numbers. My wimpy Z rated only 323rwhp with 1500 miles. I plan to dyno it again in the spring, by then it should have well over 5000 miles. I hope the hp has increased to a more respectable number.

What were the conditions when you dyno'd ?
[/B]<HR></BLOCKQUOTE>
It was early October in Virginia, and warm that day. I went with a bunch of CF members for a group dyno day. It was probably 80F and fairly humid. But 323rwhp is SAE corrected. I was not too impressed. The worst was the torque, can you believe 319rwtq. And there was another Z06 present. Ranger's Z (with about 3000 miles, I believe) had around 340rwhp. If the numbers haven't improved by spring, it may be time to order a new Z06, and sell this one.
I have 2 Z06s', my red car with 1100 miles on it pulled 343.4 rwhp & 343.6 rwtq stock! Conditions at that time were about 92 degrees. My blk car with 500 miles on it pulled 337.6 rh & 340.8 rt stock. Conditions of this run were 76 degrees, I think. This was on a dyno jet 248. The red car pulled all the way to 6350 rpm and the blk pulled to about 6150 before nosing over.
DRM dynoed 2 stock Z06s and both did about 325 rwhp. TPIS also dynoed one at about 325 rwhp. I don't think that is all that unusual. It is consistent with a 15% drive train loss.

Yeah, for some reason my Z is short on power. And I have seen Z06's made before mine and Z06's made after mine with around 340 hp, so really no solution there. At this point, I have doubts whether the extra miles are going to mean anything. I guess I just didn't break it in hard enough.
hey lazygun, dont feel too bad...just got back from the dyno and my best pull was 322.8 rwhp , and that run was after letting the engine cool down from the first two runs
(32 degrees and low humidity)I guess I was spoiled because my 98 Camaro SS bone stock was rated at 327hp at the crank and it dyno'd at 308.5rwhp...
Just did mine today and got 354.9 RWHP and 351.3RWT. I do have a Corsa exaust and Vortex. The Vortex doesn't do to much on the stationary Dyno. But I now have a baseline to start from for my next adventure.

The vortex does do something on the dyno. I did a baseline dyno then installed the box (on the dyno) and got 14rwhp. Then two months later did a another baseline then installed the power duct (on the dyno) and got another 4 rwhp. My final numbers were 355.4 RWHP and 354.2 RWTQ.
BTW if you dyno at low temps and therefore low correction factors, IMHO you get less RWHP (corrected) than you will get at a 1.0 correction. I think modern computerized air/fuel settings can compensate a little better than the SAE correction adjusts for.
I have a 2002 Z06. Recently, while driving, I'd notice the security light in the instrument cluster would come on. Twice now in the last two days, it wouldn't start once the engine was shut off. Both times the security light was flashing. Both times I waited, and kept trying, and eventually...
A friend of mine gave me Zymol polish/wax and said it was pretty good stuff. Anyone know anything about it? Is it better than Meguiars Gold Glass wax??
Does anybody know or has experienced if the small dashboard covering over the HUD area on the upper dashboard area can be pried off ? I need to service the HUD and I have to have the windshield removed and re-installed because I had bodywork and it wasn't aligned correctly. I would leave the...
I took my Z out for a drive today - it had been sitting for about 3 days. Then I looked down at the temp gauge and it was pegged out at max 260 deg ... The DIC also read "Coolant Temp XXX deg F". No warning messages or lights. The car doesn't seem to be running hot (oil temp <207). Is it...
