So what am I gonna dyno

Faraz's dyno this week has triggered my interest in getting back to Mac Autosports to see what my car will do.

Those are corrected #'s for altitude right, not the raw numbers??

Im going to guess that you pick up in the neighborhood of 50hp OVER the sstt, id put ya down around 365-370 and close to 390tq.......thats my guess.

look in the upper right hand corner says CF=STD

uncorrected numbers mean jack shit at this altitude so I didn't post that.

Yea, gotcha, so at least it figures in altitude. You should get both #'s for comparison purposes though just fun.

the key really is my baseline... I can see what is gained between each mod. unfortunately I have a ton more mods between now and the baseline and SSTT runs.

I have both numbers, the beauty of getting the drf files for the WinPEP software.

He was already at 390tq on that dyno with the SSTT

I say you will be around 370hp with 430tq on that dyno,

FWIW, MACs corrected numbers are SUPER high. Correction is much less of a factor on a FI car.

Its probably just the calibration factors the dyno uses for their wheel torque conversions. I wouldn't look at the numbers, but at the gains.

alright, I added my uncorrected graph. No way I can run a 4000 pound car 13.1@106 down a drag strip at 8000 DA with 260 HP

I think the power # corrected is about right, it just reads really high on tq. You uncorrected stock tq #'s look close to what a stock car should put down, maybe 15 less then the sea level guys, which is about right I would assume, but there is no way you were putting down 220hp stock. Thats about 45 lower then I would have expected for our altitude, maybe more.

But all intents, our goal is to see your overall gain from baseline, I get that. We will see how much it has done.

Still dont get the tq #'s though, so damn high, haha.

I think FI needs some correction factor, but not the STD/SAE one which is for NA engines since it's too high.

I'm curious to see what you put down also.

how much fuel you got in that beast Matt? I would like to see a dyno with 91 and 104 octane. See how much of a difference it is.
