You know the shop that dynos down here runs the defrost while dynoing and that runs the compressor. I didn't think about that until the last meet we had there and I left to meet everyone for lunch and my defrost was on. Next time I dyno, I'll do one with it on and the next one without and see the difference.

 

Its just so strange b/c suppsedly, stock EVO's put down 240 hp there. . . so compared to THAT, the gains aren't that huge.

BUT, the Sti's (in the same testing conditions, on the same day, as opposed to that stock evo figure that someone gave me) were putting down 240-250hp. So, i guess, in theory, my 290 hp figure was sort of correct b/c im putting down about 40 more hp to the wheels than a stock Sti . . . But then, that would mean that the EVO's are dynoing the same as the Sti's stock, and that doesn't seem to make any sense.

im running a 0-60 in approx 4 seconds and a quarter in approx 12.5 on pump gas with a cat, so i presume i can't be THAT off of the power mark, but it still worries me a bit. What can i say, im insecurrr.

 

Alex, I'm assuming you went to the dyno day in Torrance at Harmon Motive?? I almost went too. Had we both dynoed, it would have answered a lot of questions, and I could have met you, which is something I'd like to do since we are Socalers.

 

yeah, we'll meet up eventually. Im trying to drag my *** out to more events.

 

I tested that a few weeks ago the difference is around 15 whp on my stage 1...with the A/C running on full it can be as much as 25 whp

 

Hey Alex,
Apparantly you did very well, as someone named Tarmac02 on Socalevo mentioned your car as kicking some butt for only running pump gas.

Still, it doesn't answer your question about dyno to dyno differences, but this might....

It turns out that stock evo dynoing at 240 was 2005 RS. Could be that they dyno a little higher than the 2003 due to some factory tweaking of the ecu???? That's what many on the above link also were talking about. Also could be that RS owner added a gallon of the 100 octane to his pump fuel for insurance against a bad tank of gas. That might be good for a couple of hp.

 

thanks for the link smog. See, its weird, i don't know what to think, its just the stock EVO figure thats really confusing me.

Otherwise, my dyno results are consistent with everything else. A Vishnu stage 2 wrx was running about 250-260, which seems consistent with the DD.

BTW, tarmac-02 was saying that that RS that dynoed, he was running a K&N drop in (dont know how much that helped) and that he took his boost restrictor pill out.

 

The "stock" Evo RS that got 244 whp and 251 torque had a K&N panel filter, pill removed and octane booster ....

I was the 2nd Evo ever dyno'd on the Harman dyno and I got 234 whp and 244 torque, stock on 91 octane. The other stock Evo who dyno'd that same day got 4 more whp and 6 torque.

so, another question for you guys. Check out the link in the post right above mine (the socalevo.net one, and take a look at the bottom of the dyno chart for the testing conditions).

Apparently, that one that dynoed 238 was in 75 degree weather. Mine was dynoed in 85 degree weather. Could that make any difference? or is it minimal?

 

I would check out that link but I've been banned from that site. Boo hoo.

 

haha. it just shows that the dyno conditions for that stock evo (238hp) was 75 degrees, whereas my testing conditions were 85 degrees.

Ill post THAT chart, and my chart, later when i get home

 

any thoughts shiv?

 

Hiya-- I'd love to see the dyno graph. Peak numbers, by themselves, don't really give any useful info when it comes to troubleshooting or general analysis.

shiv

 

no prob, ill post it up when i get home from work. thanks in advance

 

in the meantime, heres a bit of interesting information.

A WRX wagon with a Vishnu Stage 2 dynoed at Vishnu's DD 273hp (on 100 octane).

the SAME car, on 100 octane, at the Harmon Dynjoet, dynoed around 293 hp as well.

(for comparision, my car dynoed a bit under 270hp at Vishnu, and dynoed 292 hp at that dynojet)

This seems consistent enough, until you look at the stock EVO's, which were dynoing 240 hp (which was, incidentally, about 5 hp more than STI's were dynoing at stock).

Hmmm. . .
