    If it was mid-90's, your probably OK. If it was low-90's, you were down on power. You could have just been heat soaked, resulting in a long, boggy launch. Next time you go to the dragstrip, let the car cool down and hour or so before you make your pass. Ice the intercooler, and don't leave the engine running while you are in the staging lanes. All of this will make a big difference.

    Good info, wish I had it ten hours ago. Rgw2kx I basically have the same setup as you just no tranny cooler which I do plan on getting soon.

    Lol, my stock rs was faster by .5 and trapped 89 mph or so. Obviously you have a ridiculously horrible 60' time. I have a feeling it's more driver error then anything. Only thing I'm not sure on is what a decently driven auto can do 60' wise.

    holy crap what a bad 60 ft. there is almost a whole second that can be made up with a 2.0 60ft. maybe the trans has seen better days?

    I believe you guys are both right, it was my first time ever at the drag strip and after my seventh run I could tell my transmission did not want to do it anymore.
    I'm not giving up, so time to make her better.

    So all this worry and you've only been to the strip once? lol. From how you were writing it seemed like you've been there tons of times and you can't figure out what's wrong with the car and you ran faster before.

    Here's the timeslip from my auto, but it's an 09 with a 2.5L engine.

    My old Grand Marquis ran 9.9 @ 73 in the 1/8th so I hope the OP can get it down to at least that. It's not like it was a roaring sports car but I've run all my vehicles just to see what they can do

    Come to think of it, at the time I did give my friend's stock 02 WRX m/t fits from a roll. 30-90 he wasn't going anywhere.

    dont see how driver error comes into play with an auto.
    press brake, floor gas, let off brake, profit

    you're missing something in there...

    press brake, floor gas... wait for a few seconds to build boost... then let off brake.

    If it were that easy you'd be pulling 1.9 60' times like the above auto trans and not 2.7 60' times. That's almost a full second in just 60'. That is huge if you didn't know.

    He was probably heat soaked. I learned my lessons with my old 02 4eat wrx. Engine won't rev passed 2500, and there's just a big bog -especially with the 2.0L engine. But yeah, 0.8 seconds slower in 60' costed him about 1.6 seconds in the 1/4: 15.9 - 1.6 = 14.3.

    i dont know what can be going wrong.
    i have an HKS uppipe and performance muffler installed with a tranny cooler, i dont see why my quarter mile times are so slow. any help would be GREATLY appreiated.
    from what i hear, the stock auto wrx's should be running mid 15's to high 14s times.
    Check if the fuel system is working properly.. if there is too much or too little fuel is mixed, combustion doesn't work properly.

    Find someone with a datalogger! The car will tell you everything that's wrong in like 30 seconds. Instead of playing "what if" and potentially losing the engine, get it FIXED. Daily driving it is risky right now; racing at the track is just a miracle it didn't self-destruct.

    Running lean isn't just an inconvenience. On a turbo car it's certain to destroy things. You just need a cable and the free Learning View software. It does work on an 02, as demonstrated here. That one screencap will show almost everything you need to know about the car.
