Launch Technique?..

Going to the track in a couple weeks to test out my new stall/tranny. Before with mods in sig -trans+stall..I went 13.52..What do you think I can run now with a built trans and a 3600 stall / Tune. I am hoping for rock bottom 13s anyway. My main Q is, should I stall as high as I can off the line?..Or just bring it up a little and flash it off the tree? Advice? Only my 3rd time to the track ever.

I've tried it both ways. I think you just have to play with and see what best works for you. My car launches best when I push the RPM's to the point where it tries to push past the brakes.

I think 12.5X - 12.6X is very possible.

5-6 sec. burnout. Try launching from 1K first. Next, try launching from 1800. You should get a pretty good feel for what you should try on pass #3 .

Good luck!

You want to give the converter room to "flash", but where to launch will depend on what your combo likes. As mentioned above, try a few different RPM spots, and if the car hooks really good or spins, try the same rpm again just to verify the results.

I personally launch about 1800-2000 rpm on my 3800 stall in my Nova, and about 950-1000 in the Formula (stock converter). IMHO pushing through the beams won't get you the best results, launching from the beams (giving the converter room to flash) will.

With a 3000+ stall, sticky tires and a factory 3.23 rear you should hit 12.9's

I know guys w/ just full exhaust, a few bolt on's, 3.73's, 3600 stall and a tune (stock H/C)... cut 1.6X 60's and run 12.1X - 12.2X So, yes ... 12.9 easy.
