    was the ta on slicks?



    so for $1000 you can get an LS1 into the 12's eh? I'm not doubting it, I just didn't realize it was that cheap...
    Not sure but I doubt it. Sounded like he was leaving in the 3,000to4,000 range and still sounded like he spun a little. I just put that up there to stir the pot.

    you got into the 12s with basically just a higher-stall convertor??

    I didn't think these cars would make into the 12s without an LS6 intake manifold, lid, stall, gears, and slicks

    the ls6 intake is not important to getting into the 12s, a stall and DRs is pretty well enough

    an A4... with street tires.... what would it take to break into the 12s??

    while maintaining streetability...

    a 3000stall would probably still be streetable, right?

    Yup. Been racing for quite a few years now as well, and knowing how to launch can be very beneficial. I immediately tuned the engine the day I bought her, but I don't consider that a bolt on (it obviously helped though, regardless)...

    Still contemplating either a Turbo or S/C, which is the main reason I haven't delved into cams just yet. I'm leaning more towards the ProCharger, to be honest. The stock heads, TB and MAF will be tended to... and will more than likely be opting for a polished Weiand intake (ported, of course), and an LS6 cam. I know there are better cams out there, but these seem to respond quite well w/boosted applications.

    I wonder what you can do at the track with just the lid, LS6 intake manifold, and a higher stall on street tires?? I don't wanna mess with the cam or anything until I get around to completely rebuilding the motor...

    Put some DRs on there and make full use of the stall, easy 12s

    It's all about who's got the mods and the better driver. Stock for stock it is a driver's race in the 1/4 and a win for the STi if you're not at least on drag radials.

    We all know that it is cheaper to get an old V8 down the strip faster than a small turbo H4.

    Way too much credit to those dirt buggies! Dude, you need to come down to America and get your ass handed to you by an LS1. Cause apparently, you aint raced any.

    how much work is it to tune the computer to not freak out if you use a cutout before the cats? wouldn't that be some easy hp?

    If you can achieve a decent sixty-foot, then high 12's is definitely not out of the question. There have been cases in which skilled drivers brought essentially stock LS1 F-Body's into the 12's....

    Take it easy while launching the car w/slicks, or you'll be rebuilding more than just you're engine....

    Why would I need to come to America to race a Camaro? I've raced numerous LS1s, lost a few and won a couple, so um, dude, get a grip. Why don't you come to Canada and race me with your Camaro on a road course and I'll show you what these "dirt buggies" can really do.

    By the way, Toronto Motorsports Park (Cayuga) is close enough to the border that Americans come to us (it's a great track), so who knows, I might have already run and beat an American.

    The PCM shouldn't kick into Limp Mode by bypassing the cat-cons, if this is what you're referring to. It's just a matter of enabling/disabling... and refining the tune.

    Certainly looks like a Camaro to me (see attached pic):

    Here are a few stage 2 (exhaust + tune) slips:

    12.5 @ 110 (NOT the norm for stage 2):

    etc.

    Not saying that is fast, but not bad for a 2.5L 4 cylinder with a tiny turbo.

    that looked like an old-gen single turbo supra... like an '88 or something...

    It's not, and even if it was, it's at minimum 15 years old.

    there are some honest guys here, but most just love their cars and no doubt there gonna defend it againts a ricer/dirt buggie. But as it was stated in the past 177 post's ITS A DRIVERS RACE. (from a dead stop) from a roll i dont care wut u say stock for stock the LS1 will tear apart the STI. But from a stop its a drivers race.

    well a friend of mine and I raced a couple of weeks after I got my '02 z28. He had an '04 STi, he had a boost controller, took off his muffler and had an aftermarket blow off valve (don't think that adds to any HP, just saying what he had...) he had the boost pushed up about 5 or 6 PSI over stock... from what I've heard you get 10hp gain for every 1 PSI of boost... I don't think so.... but anyways my car only had/has a cat back magnaflow exhaust, and a K&N air filter we raced both from a dead stop and from a moving start... I also had another person in the passenger seat recording the whole thing... but each and every time we raced he beat me by at least 2 car lengths... This was in the middle of december and at about 11ish at night, and where I'm from thats about 40 degrees or so outside. On the line I couldn't rev it at all because I would sit there spinning them all through first, so I had to just lift my foot off of the clutch and slam the gas at the same time... which don't equal a good jump... anyways I even through a couple 20lb weights in the trunk to give me more weight... that worked off the line... but in the long run he took me by even more than before... I'm pretty sure that your T/A with cat back will be able to at least keep up with a stock STi. Don't know if you know this or not, but according to kelly blue book they actually weigh a hundred pounds more than your car stock! So with your 350 under that hood your still lighter than that bulky AWD system! Your right though they kill off the line, just because they can rev to like 6k rpm and then drop it... It's not true for all AWD cars though... I've also raced a late model VR4 3000GT off the line, and he did rev it to like 6k, and I still had him off the line... he was a veteran driver too, has many more races under his belt than I do... so it all depends on the system they are running and all that junk... so good luck!
