I am not fighting over it. I am going to the drag strip sometime in the next few weeks. Can't wait to see what runs.

Bad guesstimate... Why are you looking for et too?

A 12.2 with 270whp falling on its face after 5k rpms? That's not going to happen because he can't take advantage of his gearing. If it was making 270whp at or close to redline I'd say a lower 12 sec pass may be doable. As it sits if you can get anywhere in the 12's you're making some decent power for that little turbo. Not to mention ET usually demonstrates driving ability where trap speed indicates how much power you're making given the weight of the vehicle.

And OP don't feel so inclined to show NASIOC know-it-alls your car is making power at the dragstrip. You're going to really regret it if you blow your trans on the launch and you're certainly making enough torque to do that.

Well Gents... I emailed the fine folks at Pacific Raceways to get more info on their "Test & Tune" events and it JUST SO HAPPENS that yesterday was the last day this year that they were holding the event to the public.

BIG props to Ed Garfield, the drag strip manager, who not only gave me all the info I was looking for, but SUPER quickly. I emailed him yesterday at 11:46am and he replied at 12:03pm. Crazy good customer service.

I really enjoyed myself, but I was disappointed in my times. I couldn't get a good 60' or even 330' time... just didn't have the low end to pull while the turbo spun up. Once it did.. super happy.

I tried a mixture of launch set ups to see what worked best:

Full auto with t/c on and off (quickly learned that TC has to stay off; something that Dom noticed on the dyno as well)
Sport mode with t/c off
Manual shift with t/c on and off

The best seemed to be in sport mode with t/c off. I staged, held the brake pedal down and rev'd as high as it would go without moving forward (about 2200 rpm).

I wish the Forester has a stall converter or the Access Port has launch control as an option like the WRX/STI.

My best run was:

R/T .344
60' 2.515
330 6.313
1/8 9.304
MPH 81.59
1000 11.901
1/4 14.084
MPH 103.72

I'm OK with the end speed, but I REALLY wish I could launch better. I think I could easily be in the low 13's or better if that were possible...

I seriously doubt that I could be in the 12.75 or lower range w/o E85 or a manual tranny

BTW, interesting calculator online... post #2

http://www.turbo-mopar.com/forums/sh...ile-calculator

I don't know if my math is accurate here. I am relying on Google to do the math. Comparing it to the #'s on the thread above, it checks out.

Based on it, my breakdown is (3700)*(.4541155866900175)^3 which according to Google is 346.498173488 WHP... which is .998173488 HP off Dom's dyno. Less than 1 HP off.

Clarification: I'm not supporting/advocating my dyno results, just stating what I believe to be the most accurate method of calculating the WHP based on what I can find online.

That being said, I've seen 350 HP cars run low 12's, so I still have my doubts, not to mention I couldn't launch for s**t.

Pretty sure the HP calculators are estimating engine power, not WHP

Aren't these dynos traceable to the NIST?

Actually, if you look at his breakdown, he says 606WHP (his numbers)

So this stock 09WRX would be >300whp?

Again, it's not my calculator. YMMV, it might be totally wrong, just pointing it out.

with the tq that car produces you should be able to short shift and stay in the powerband to get down the track faster.

at 292/292 on my 04 STi on PIA's Mustang Dyno when I dyno'd my car after running a 12.29, so I would imagine if the #'s are correct and with a car that weighs 100+ lbs less than that STi did, a 12.2 would be a very possible outcome.

Back to the dyno discrepancy... it's not as much as I had thought it'd be, but it IS there.

More progress. Had a ton done, including a 4EAT to '11 STI 6-speed swap. Bigger injectors and re-tune on a more conservative dyno (PIA's Mustang).

PIA dyno base (RUN 2) (no additional mods) = netted 326 AWHP / 379 AWTQ

MPS dyno base (same mods as the PIA dyno base) = 346 AWHP / 414 AWTQ

NEW PIA dyno (RUN 1) (injectors + 6-speed) = 360 AWHP / 358 AWTQ @ 21psi.

Next up = E85 tune. I'll get it in a week or so. I'm hoping to move into the 400AWHP club, but it's going to be close!
