This was my first (and last) time I have ever been down the track. Everybody told me to avoid the spray puddle and how to "stage" the car. I launched the car at about 3800 rpms (though everyone said launch it at 6k) since there was an STi there that ran a 12.5+ with just a TBE and on his second run, he grenaded the tranny for launching it at 7k. :eek: :eek:
This is what the time slip looks like;
r/t .629
60 2.26
330 6.101
1/8 9.162
mph 80.79
1000 11.742
1/4 13.959
mph 101.96

I thought the car would have been a bit quicker (310awhp) but all my buddies were saying that I should be very happy since it was my first time ever going down the 1/4. I was to afraid of launching it because of what happened to the other STi that broke his tranny. I know that there are a lot of STi owners that are shrugging their heads at this, but hey, I learned my car isn't as fast as I thought it was. There were a few WRX's that were in the very low 13's. I almost had someone run it for me but I would be pretty pissed if something broke and I wasn't the driver.

Your car has 310awhp? What mods? 310awhp via?

~v6

I guess sti transmissions do break.

I am curious as well :confused:

Ya, that too :eek:

Thats not good.

I guess sti transmissions do break.
I am guessing that it was an axle and not the actual transmission.
an axle should break before the transmission.

10 bucks says the tranny didnt break.

another 10 says it was an axle.

i sure as hell thought i broke my transmission when i broke my rear axle. ;)

he prolly doesn't mean 310 @ the wheels

oh, and to the topic at hand...the 60' could use some [a lot] of improvement...and it looks like the shifting could as well.

but like me, you wont be going to the track, so oh well.

i broke a rear axle over a year ago at the track...then i did my stage 4 installs...and i still havent been to the track. i just know its fast. i can hang with [very slightly] modded cobras on the highway, i dont really need anything else to make me happy.

yes, to the wheels.

The STi in question was a wingless silver one. Robert from Forced Air Technologies is the one who told me about the tranny. I don't know if they knew the guy but they did say he "grenaded his tranny from the 7k launch" and that made me very hesitant about launching.

you ran a 13.9 with an sr50???

Like I said Happyasian, I know there will be a lot of STi owners shaking their heads about this one. I am not going to glorify my times. Why should I? I for sure thought I would be in the low 13's since there were a few WRX's there with 260-270 whp that were in the low 13's. I have read many "launching" threads this past week and would have launched it at 6K till I spoke with Robert from Forced Air Technologies. I almost pulled out but I thought to myself "wth, I am already here, so baby the launch".

well, ive considered going to the track and just rolling off the clutch and running just to see what i would do with a rolling start...

...i always figured i would get at least low 13's...

:eek:

I would've thought you'd run faster than that even if you had a crap launch...

yeah, but a rolling start? eh. the sr50 has some lag in first.

balls out, no doubt i would be deep into the 12s.

Please post your dyno results sheet. That's a lot of power for a 13.9.

I agree with your buddies, if it was your first time you did well. I pulled a 14.2 at my first 1/4 mile. Same car many tries later I run a more consitant 12.7

You have to launch hard to get the good times I find.

Cheers

Mick_The_Ginge - Just replaced my 5 speed with a JDM 6 speed

haha but what were your mods when you did your first pull

Don't sweat it...if you wanna give it another try, work on launching the car, and shifting faster. Shoot for a goal of 1.7 60ft or lower and mph over 107, and you'll hit mid 12's.

Same day, trust me I can tune but I can't drag to save my life. Bogging down on the launch was my main issue, I did not want to break my little 5 speed. Once I got the launch the times came right down.

I ended up breaking the tranny at a track session, no launch involved, just a couple of hours of hard driving.

You guys are so hung up about his time(driver)but nothing about his speed(car) which tells you his power is way down for those mods.

or he should shift faster. My guess is a minimum of 107mph, what do you guys think?

I don't even car what he ran. I'm more curious if the STi that had problems was due to grenaded trans or a snapped axle??? I think the guy could have F'ed it up if he was launching at 7K, but I wanna know for sure.

Did you ever find out about that for sure Jayhawker?

I will try and find out. Again, I was speaking with Robert from Forced Air Technologies and I was asking him about launching and he was saying "that guy who ran a 12.5+ earlier grenaded his tranny because he was launching it at 7k..."

I will post in the local forum and see what happened.

Jayhawker if you ever want a fellow STi brother to go to the track with, hit me up on PM. I have my car tuned by the guys at Dyno Comp same as you. I'm still on the stock VF39 pulling a 12.74 @ 106 with a badly slipping OEM clutch. You shouldnt worry so much about the tranny if you drive right. Let the clutch take all the abuse, and slip the hell out of it. I also dont bang my gears by power shifting, as I dont see the point in getting another maybe .2 off your ET. Just isnt worth it, I lift off the gas every time I shift. Your trap speed should also be alot higher. You may want to check with Richard @ Dyno Comp to see if you have an up pipe leak. So once again if you want a local to go out with, hit me up. I'm always at the track either with my STi or watching my wife run her 10 sec. soon to be 9 sec. Mustang.

I have launched my 6MT all the way up at 8000 :eek: and then it was already broken anyway. What was broken was my 5th syncro from a bunch of hot laps at E town.

Otherwise I don't see how someone could break 1st on a launch? I have been abusing my trans street and track and have only managed to break both rear axles on a killer launch ;)

Guess will have to wait and see what he did break :confused:

This is a driver issue for sure. I've completely bogg launches and got off the line faster than you. With your setup you need to come off the line with a lot more rpm. Down low your car isn't going to pull hard. Its also going to take a lot longer to build boost if you bogg. You need to keep the engine in its power band. Otherwise your dead in the water.

Good example . There was a guy running low 14s @ 102 mph with a Stage 4 Setup. Yes a stage 4 setup on a 02 WRX and only low 14s at best.
The guy was nice enough to let me drive it once down the track. I pulled a
12.7 @ 107 mph.

There goes the low reading dyno theory.

How much boost are you running?

Your trap speeds are terrible for 310awhp - you'd have to be REALLY granny shifting to get those traps.

In my SR50 on pump gas, I never trapped lower than 107, even on poopy passes. I only dynoed 325whp on turboXS's dynapack. (Which is what, 170whp on a DD?)

You may want to have your car checked out to see if there's something wrong.

With the same mods as you (txs utec and tbe instead of APS and ecutek, and still stock TMIC), my best pass was 12.49@111mph with a couple squirts of GT104 mixed with 93.

I was able to pull a killer 12.6 with a 2.1 60' and I was trapping @116 :D :lol:

Are you launching in 2nd?

quote from horshack

"Hey, that was me....

On the 1-2 shift I ripped the shifter right out of the cup it sits in, couldnt get third.

Limped home shifting with the linkage directly - new parts on order, be here Thursday."

I am running at 19lbs of boost and then it tapers down to 16. I do remember that I did shift the car into 6th gear. I am pretty sure that I kept my foot into it till I saw the light come come on at the end of the track to let me know I passed the quarter mark, but I was getting a bit scared because I didn't know how much room I would have to stop. The car pulls like crazy and I know it's running fine. I just suck at dragging the car. Now I know what people mean when they say anyone can go from roll, but not from a dig.

i've been to the track twice and the first time i wasn't reving high enough and the car would bog and it could tell it aint healthy...second time i reved like crazy and let ti rip with the DCCD set all the way to the back and it would feel really good...i mean it even felt healthier for every thing than boggin...i would get a little wheel spin and then it would stick...my .02c

Is that a typo, or did you actually shift into _6th_ gear? That's certainly a problem there. You should be halfway through 5th at round 110 or so MPH at least. Certainly not 6th.

Interesting.

I think it's not the drag racing ability that's in question here (certainly there's room for improvement
;) ) What's confusing, at least to me and the other poster who mentioned it, is the trap speeds. You can screw up the launch all you want, but if you shift reasonably well, trap speed is a good indicator of horsepower. And your traps are what bone stock STis trap, or indicative of ~250awhp (on "normal" dynos). Was that your only run of the day?

Yes, it was my only run. I do not have the print out out of my dyno sheet or I would load it up here for you guys to read. I was close to red line that is why I shifted to 6th gear. I thought my shifting was good. I did not power shift. The next time there is an event at Firebird, I will have another driver take my car down the track and post the results. They are open on the weekends so in a few weeks I will post up some different #'s I hope.

Your saying at a 100 or so MPH, you were redlining 5th gear. :confused: Dont you find this at all odd? Now I have never driven the 6 speed, but I know that cannot be right. I thought 4th gear ended somewhere near there. If you really went into 6th, then I would guess you have a slipping clutch. Which would not suprise me. Which clutch is it by the way? I am thinking mine was doing the same thing since I kept nailing the limiter at 109 in 3rd when 3rd gear really ends at 113 or so. Not as drastic of a slip as in your scenario but my .02.

Well, I guess I wasn't "close" to redline. I was shifting at 6400 rpms because that's what I had the shift light at. I thought I had it higher and I just confirmed it. Oh well, I owe it to the car to take her out one more time to see what she will do.

Hey Jayhawker if you want, I'll give you a ride in my STi and give you some pointers. I would definitely be wary of letting someone else behind the wheel of your car. Trust the tune that Dyno Comp gave you, and just floor that gas pedal. I shift my VF39 @ 6800-6900rpm. Like I said the wife and I are always at the track, so shoot me a PM when you wanna head out. We prefer Speedworld over Firebird, as I've found it to be a faster track. Dont know if you live on the west side of the valley, but you are more than welcome to cruise with us!

Thats my problem pretty much too. I have or had a JDM 6 in my car and we set the redline so my 4th would be good for 120mph.

When I pulled my first run I was bouncing off the limiter in the traps and the time slip said 112 :confused: The clutch wasn't liking it at all :rolleyes: I really hate to have to shift into 5th it's such a PITA...

Your car did NOT have 310 DDwhp that night, on that pass, if you pulled a 102 trap...sorry....

Either you were losing power through a slipping clutch or ECM pulling timing....something.

Or he drives like my grandma.

My bad gys, I DID NOT put down 310, but rather 301. I have a copy of my dyno plot, but do not know how to load pics. I can take a pic of it, and forward it to someone who has the ability to upload pics here. Is 9 hp less going to make a difference?

AZ2004STi, I will definitely PM you when I am ready to head to a tracj again.
I plan on getting an APS CAI soon but I am not to sure that will help out with anything.

310 Horse at the wheels and you ran a 13.9? A stock Forester XT will do that.

I'm going on the clutch idea personally... Even shifting at 6400, unless this is 301 WHP in a 500 RPM span, this should be trapping AT LEAST 106-110 MPH regardless of 60', just rowing through the gears.
