First time at the track =/

[ktmr1der03]

Hey all, I finally registered although I have been viewing this forum for over a year. I have a 2005 STI, protuned Stage 1 at 312Whp and around 315?wtq. I was at the local track last weekend and was not impressed with my 1\4 mile times.

It was 87 degress out, near sea-level, and I was running 13.5's with a 0-60 of 1.7-1.8. I was shifting well and fast right at redline. I have heard of people on here with around my hp\tq running high 12's. Does it sound like I may have something wrong with the car and lacking power since last dynoed? Or does temperature have that large of an effect?

Any tips for a better time? Thanks a lot!

your protuned stage 1 at 315whp? that must be a pretty aggressive map. neways welcome to the club. to see fi your losing power try to see if you can get some datalogs or see if you can hit the dyno. are all of your fluids good?

Sounds like someone forgot to correct the dyno readings. Realistically you're making about 250-260 whp.

I was tuned at P-R-E in Portland. All I have is a down-pipe, everything else is stock. I have the dyno prints somewhere, but it shows 312whp, stock run was 245ish.

What type of dyno do they have?

Edit: I looked on their site but couldn't find what they use.

Edit: Found something from a vehicle they tuned. Dyno Dynamics Dynamometer it says on the sheet.

There is a thread on here posted by P-R-E showing the results they got from a bone-stock STI. It put out 298WHP and 318WTQ.

Maybe I'll get a dyno run at a third-party shop.

Sounds like seriously inflated or uncorrected dyno numbers to me. If you are putting down that kind of power with that 60' time you should be running high 12's to low 13's. You should probably be shifting well before redline. My 06 was protuned with a downpipe and made a little less power, and they gave me a printout of the psi at the entire rpm range. I found that I ran the fastest shifting at 5500 rpm. ran a 13.1@103.5 with a 1.7 60' time at 270whp and 295 wtq tuned at 18.5 psi

dyno dynamics dyno is usually one of the highest reading dynos out their. Their is a great article in the newest issue of modified magazine. It compares every kind of awd dyno. Il list the results for those who cant get the article. the test car is a 06 evo 9 that is stage 2.

mustang dyno-292.7 whp
dyno dynamics-318.6 whp
dynojet-312.5 whp
dynapack-324.4 whp
dynojet-315.9 whp

Ah so you're stage 2 then, not stage 1.

yeah i picked up on that too. (after his last post about the DP)

[ktmr1der03]

I wasnt sure if just having a DP and tune meant stage 1 or 2. I thought stage 2 was turbo-back exhaust.

So going to redline is not the best way to drag race these cars?

you have to see where the motor makes peak hp and tq. my motor makes peak tourque at around 3800rpm and peak hp around 4800rpm. By shifting at 5500 it puts me right back down in the meat of the powerband. Power drops off above 6000rpm so if I was just to shift at redline(which I did first time at the track) I would run 4-5 tenths slower. a good tuner shop will give you the printout of the powerband and psi along with the peak hp and tq numbers
