Dynoed my 2007 Z!!! *GRAPHS*

fwdracer1838 · 09-06-2007, 08:51 PM

I dynoed the car today....about 900 miles on the clock. Probly going to do another run when it cools off some and she has more miles... Considering what others have been getting, i was a little disapointed, but it was hot and I'm sure after the engine is fully broken in I'll see more. I was surpised at the A/F ratios being as rich as they were to...

257 WHP/ 224 WTQ was the highest.....@ 94 degrees and a whole lot of humidity since it has been raining all week.

Ouch... about 10whp/10wtq too low :/

and a crap load richer, mine was completely flat at 12:1

yea...tell me about it....i think it has a lot to do with temp and or the fact that its not broken in all the way.

Eeehh, maybe. Could be you've got the Z that gains 10whp with an intake cause it'll "fix" your a/f. Who knows.

LOL...i guess...either way i'm waaaay happy with the car.....mods are sure to come..

yeah u r def in the 26X'srwhp with cooler temp....you're fine. Alsowhy did you dyno a car that wasnt broken in yet? Take it back in a few months when the weather's cooler and you are completely broken in, I'm sure you'll see 265rwhp easy.

Why shoot for the best conditions to dyno in? A more realistic would be to pick the average conditions for where you drive and dyno it then. Afterall, do you want to know how your car runs most of the time, or only under rare conditions?

The plots are corrected for Temp and Humidity..

well the dyno was a dynojet 224xlc which is better than a standard 224x, it has the eddy current to load the vechile with....while my car wasn't loaded...the roller is substainaly heavier than the none eddy current...almost twice the rotational mass, hence the lower number.....

fwdracer1838 · 09-07-2007, 12:40 PM

^^^ this just is case and point to the fact that all dynos are a bit different and conditions play a huge role in the runs.

can i just get an 07+

That's definitely rich, though it's not CRAZY rich. My wife's car(07 sedan, same motor) runs even richer than that; at 7 grand, it dips down below 11:1. Here's her chart:

Your numbers are good, it wasn't a straight inertia dyno. They can turn the 224xLC into an inertia dyno, just sounds like they didn't switch it for you. Don't bother comparing your numbers to anyone running a 224x, 248x, etc.
