Finally hit the Dyno

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.

Tom:

Those are very represenative numbers. Nice interior, I almost got it, then opted for the black, my loss.

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.

Those numbers look a tad low for a Z06. I would definitely dyno it again after a few more miles. What were the conditions when you dyno'd ?

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.

Don't sell the farm just yet. Give it another 1500 miles or so, then re-dyno. Bet the #s get better with age.

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.

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.

That problem will be remedied on the next one...

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.
