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.

[forza1976]

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.

I'm gonna guess around 375 hp and 410 tq.

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

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

Holy crap I looked at the wrong #'s.......you got a freak Matt...no wonder you cant launch for shit that car is getting 430tq!!!

Wow, those tq #'s seem super high for stock and then the SSTT. Especially xi.

[ar design]

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

[raceyBMW]

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

A Honda can do that!

not exactly an equal comparison

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.

[forza1976]

Word!

I'll post up details early afternoon tomorrow. I'm picking Craig up to go see how it does at noon tomorrow so I'll for sure report back.

[mattsfeir]

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.

[Bimmer This]

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.

[forza1976]

all 91 pump... no good stuff

[Bimmer This]

I wish I could have gone with you.

[forza1976]

we'll go again Vincent. I know you have a lot going on this weekend and next

[forza1976]

Updated the first post with my new dyno comparison to the baseline. Corrected STD

[Dackz]

WOW 110ish HP and 120ish TQ..........nice. Thats huge improvement
