    Default Finally got to the track

    82 GT 347 650 Quick fuel, TF 11R Heads, 5 Speed 3:73 Rear gear.

    Lots of wheel spin and tricky to launch with used up Nitto 555 tires. 60 ft times are awful but the MPH is promising. Happy to see it get in the 12s! I feel I can get in the mid 12s with better launch practice.

    I don't think you'll have any problem getting that combo into the low 12's with that mph. Probably could hit 11's with a good launch.

    We're not fast racers, we're more what's known as half fast racers.

    That is why I hate drag radials on a stick shift car, but you should be able to get a 1.9 on those Nitto’s if your lucky. That would give you a 12.50 easy.

    Install a Line Loc, buy some bias ply ET streets, do a big smokey burnout and get that 60' down in the 1.6 range. You'll be running 11.60's - 11.80's @ 116-118 mph! I'm guessing that you have about 420 hp at the wheels. Nice!

    A T5Z's 2.95:1 low gear might help you off the line more than a typical 3.35 low gear would with a 3.73 rear gear.

    Put some good slicks or drag radials on back and optimize pressure. Get some MM adjustable lower control arms on there. Disconnect the front swaybar links. Run around 1/2 a tank of fuel in the car to help with traction and weight transfer.

    Launch in anger and shift with your foot on the floor -- screw the thoughts of a broken transmission.

    My bet is you'll see an 11.30's or 11.40's with that trap speed if you do those things.
