Yeah i know he uses data logging to tune it. He is a very credible tuner in my area, just about everyone uses him and ive never heard a complaint. And i think i would of definitely been in mid to high 12s if i would have launched harder, and i didnt even heat up the drag radials or anything, i was scared to death after reading all the horror stories about all the ppl who have snapped their axles with drag radials and their stock rears. Just launching at 3k after launching at 2500 was a .5 difference in my time

your stock 8.8" should be more than enough with your power levels.... they are not exactly toothpicks

+1 my 79 had a 7.5 with slicks , I launched at 3000 somewhere around 50 times . never broke , lol a friend suggested a 4500 launch , that worked 2 times !!!! 3rd time made a nice video high light !!! POWWW !

Launch that car. Even IF you happen to snap an axle, its a cheap and easy upgrade.

yea TBird has a h/c/i motor and he was dropping the clutch on slicks at 5k for a long time. i will say he tried it at 6k and the stock rear end said NO...but still thats leaving hard..

And to answer some other questions, i am not intercooled, and i am only running 6 lbs of boost. i have only raced at the track about 3 times, so i am by no means a professional, its not really a track car, just wanted to take it to see what kind of time i could get, if i go again i will have to try heating up the tires and launching a bit harder

That sounds a lot closer then. Leaving easy on only 6lbs, non-intercooled, etc. On that note, I'd say the car did OK. Definitely a lot left in her

Next on the to do list is a pulley swap, and either an intercooler, or meth injection. Which would be more beneficial/cheaper?

Meth, it will cool the AIT's and will raise your octane, you will be able to run a more aggressive tune, more timing, etc.

Get both if you can afford it.

Nitrous gets really cold! Haha...

I got an air to air and a progressive meth controller , I use meth as a safe guard . the air to air really works fantastic . been playing around with the meth levels at the track , never ran better numbers with it , but it more of a safe guard rather a performance tool . but spray to much to soon , and you will see your numbers go to hell !
