Sorry for the size of the file (in deminsions, not file size it's only 330k)

This past Saturday I went to Dynotech tuning to get my car dynoed. My friend and fellow DSMer opened the shop a few months ago and (shameless plug ahead) does mods and tuning of turbo DSMs, EVOs, and other cars.

Allright on to the runs, I did 3 runs. The dyno used was an AWD Mustang dyno, set up for 2WD of course. The runs were corrected to SAE standard conditions for temperature, pressure, and humidity. I think it was 2-3HP lower with the "raw" numbers as it was a little warm that day, but not some large amount off due to the correction factors. There was about a 15 minute wait in between runs, and the car started off well warmed up to begin with.

The first was on the stock ECU. I got 148hp and 116 lb*ft of torque. The curve on the top end (6200+ rpms) was a little rough compared to the next runs.

The second run I swapped in an AFX ECU. I know it is supposed to give more power if it runs for a while instead of "reset" like it was so the numbers may be a little low for the ECU, but this was the best I could do with the car strapped down and limited time. This second run the HP was 151, torque 118 lb*ft, and the HP curve at 6200 and above looked a little smoother. With the AFX ECU the curves were a little higher (2-4hp, 2 lb*ft) everywhere in the RPM range, not just at peak or only in a narrow range.

The image for the 3rd and best run was below. I gave another run on the AFX (assuming it might do a little better) and the numbers increased slightly to 152hp and 119 (rounded off) lb*ft of torque. If the ECU is allowed to run the car for a longer period of time I am guessing another HP or two should be possible.

The torque curve is pretty flat and doesn't start to drop off until 6500rpms, and even then not drastically. The HP curve climbs until just about 7000rpms and then doesn't drop off all that much. Overall a rather encouraging curve, peaks much higher than stock. It's good to see the ECU doing something. Also, I think this proves a higher red line would allow me to see more gains. I don't know exactly what this means for crank HP as it is a different dyno then most people use and gives different numbers.

The mods on the car (for power) are as follows:

Cold air intake, 60mm throttle body, extrude honed intake manifold, mild-moderate headwork, 3 angle valve job (supposed to be a very good 3 angle job) with stainless steel valves (stock size), crower valve springs, titanium retainers, crower stage 2 cams, 4 to 1 stainless steel header (rather short runners on it), 2.5 inch high flow cat, muffler from a GS-T eclipse, AFX underdrive pulley, and depending on the run above an AFX ECU.

Hell yeah!

Congrats. You are in third for the DD camp :)

And hes not even squirting! AFX control, which is more impressive looking at his times. This man can drive.

I am trying really hard to say congrats, but I really just want to cus you out. This is bullshit within a year I have gone from 2nd in the DD whp school to 4th, what the hell!

Also, why do both you and colby have such low torque? This puzzles me... Screw all three of you and I hope you guys can sleep well at night know I am going more into debt just to re-dyno and get back my crown!









p.s. Congrats, nice numbers

I wondered the exact same thing. Your numbers were close, my numbers are quite a ways away from each other. Bulletts are too, 218 and 175. Wish my car had more torque....

Also, cheer up, because so far you are the only one of us besides bullett ( that I know of) thats broken the 14s barrier.

Hows the order go?

Bullett 218
Teklein 170
740 Turbo Brick 167
VX100 152
Fotown Talon 148

Next that I can find is Warmage12 with 117.

Either way bud, you seem to be doing something Im not, beating me to 14s.

fixed :P lol jk

Sweet numbers Todd and you're correct, the AFX numbers will continue to climb as it adjusts. Excellent that you went SAE corrected. Level playing field using SAE correction. Yeah, the torque does make me go a little "huh?" Probably higher comp would help that along.

Meh, just to be more accurate. It was such a little difference i didn't change it. I mean it wasn't over the 220whp, lol.

Thanks very much guys. As to why the torque numbers are low, I can't be sure. Maybe because the power curve is biased to not drop off in the high rpms? Either way it's decent HP.

As for SAE correction, my friend who owns the shop always uses the correction factors, and if he didn't I would have asked him to do so. Correcting to standard conditions just maks sense as you should try to get as accurate a number as possible, not fudge them higher.

Those are some hella nice numbers, esp for a fresh reset on the ecu. I would imagine, just as you have, that you would pick up a couple more whp and probably a good bit of wtq from it leaning things out...

Mikey is just being funny about his 133whp because thats what his car made on 6 psi a couple of years ago....no joke, I'm not being a smart ass! I also had to put mine in there in last so far it seems, that was on a stock intake manifold, v2 intake, ebay header, ebay 2.5" exhaust, AFX udp, stock ecu for what its worth. Now enough clogging Todd's thread up, congrats Todd, can't wait to see some even fast times out of you :D
