    Power wise or with sticky tires??

    I know I have mentioned it previously in this thread.
    Sticky tires, stall, gears.

    Much more than $1000.

    If you get a perfect condition and can get decent launches on street tires a full bolt-on car might be able to pull it off.
    Full exhaust including longtube headers
    LS6 or better intake
    Airbox lid
    Underdrive pulley
    Etc...

    Gears/stall would be a HUGE help.

    Ok how about porting the throtle body and heads and raising the compresion a bit and getting a good tune. That woulnt get me mid 12's? maby a good ramair hood with a ls6 intake

    Raising the compression requires new heads, or at least milling your stockers.
    That will help get you there, but isn't easy. Milling may be $100-200 but you will need new head gaskets and bolts, and the labor is....a LOT!
    Porting the throttle body is a good bolt-on as well.
    Tune will help...but that again is $500 for a dyno tune. Normally not worth it unless you are already full bolt-ons or have done some internal motor mods.
    The ram air hood would be around $700 new unpainted and worth at best 0.1 in the 1.4 mile.


    Cheapest way...
    Stall, gears (3.73), and stickier tires. A drag radial would help more than you know with an automatic.

    You know...that would probably be the best bet.
    I should have mentioned that.

A few odds and ends you will want for your nitrous and you'll be just under $1000 and running in the 11's. Best bang for the buck hands down.
    Sounds like a good solution to me!

    My car has no dyno tune, just an ls1 timing tuner. It gets 26 to 28 miles per gallon and is 100% streetable with nitrous. Thats the best thing about nitrous its not always on only when you need it. The day before I ran 11.80 I drive it 350 miles round trip shopping with my wife. Drove it to the track. It is safe if you make sure everything is working properly. We are putting 100 hp shot to our skidoo Mach z twins and getting 270 hp out of a two stroke twin all day. Absolutely the best horsepower for the buck.

    I ran an 11.73 @ 122.4 on stock 16" wheels with street tires, full bolt on, cam-only. Not impressive 60's, but it's possible, and my rear (apparently) won't support Slicks. Back on track though, my car's a solid 3k in parts alone. The only way to hit mid 12s for less than a grand is nitrous. If you bought used budget LTs, stall and gears, installed them yourself, did all free mods, and had the car tuned (keeping in mind it'd have to be one heck-of-a budget tune) you could probably hit your goal. Keep in mind the fast-cheap-reliable idea though, you're heading in a bad direction.

    A huge perk to N2O is the fact that it doesn't affect your normal driveability. Turn the bottle off and you're back to stock... well, minus a few degrees of timing. Personally I'd just practice some patience, and follow the normal bolt-on build up. You watch pinks? Even when professionals build up a car in a rush, things are bound to go wrong.

    I don't believe this.

    I run 12.0 at 116 on 1.68x short times.
    You would need roughly the same short time...which isn't happening on ANY street tire.
    Please prove me wrong.

    No offense, but there's no way in hell Dad's car is running 12.40 on stock width tires! He would have to be trapping at 130 to make up for no traction. I'm 54 and was at the track when these cars were new, a Hemi or 440 Six Pak would run high 13's to low 14's in perfect conditions on the stock tires.

    Aha, ya got me. I was about to get all huffy and argue with you, then I sought out the time slip... and... and... oops. that was a 12.4 @ 116, nearly a year ago pre-cam, tune, etc. Edited to 11.73 @ 122.4.... still embarrassing short times; how are you cutting 1.6 60s? Ya got a 12 bolt in there, or are you an A4? Next trip to the track and I'll be wearing some ET Streets, testing my luck with some low RPM launches. Anyone know a good alternative to 2k worth of 12 bolt or 9", or is building the 10 bolt entirely hopeless?

    Edited for "I typed the wrong #." I typed the speed from a different run, just noting that I edited my post, so if people read it, they wouldn't get confused as to why the issue of #s not matching came up.

    Nice setup, I'm in desperate need of a 9", or more specifically, I'm in desperate need of 2k spare change to buy a 9"... It's a shame banks aren't easier to rob, huh?

    I have seen a lot of cars get broke with Nitrous, mainly because they do not know how to use it.

    I also have seen people save a lot of money by having club members come over and help remove the LS1 engine to get it worked on, and then the Club help reinstall the engine.
    All for a few beers, brats and burgers.

    This guy's car looks stock, but is fast as hell.

    You can always get with your local club and have them help you, even if it is a 45 minute drive.. If you do not have that available, then you will have to have some $$$

    Maybe try a Stall converter, and different reare gear, and maybe some different tires.
