What is your launch rpm with stall? As the title implies, I was wondering what rpm you stalled guys bring it to just before you launch? Even with DR's can you acheive near full stall rpm? I know without a transbreak its very difficult/impossible. This question is directed to the footbreak guys. Example: with a 3800 stall do you launch at say 2500-3000?

With DR's I can't get anywhere near full RPM at the line before I start pushing the car forward.

I did get as high as 4000 but the trans didn't like that too much.

I stall mine up to 2200 or so and let her rip from there. no problems with traction on MT radials but my car is pretty much stock with the mods in the sig on a speed inc Basic tune. I managed consistant 12.70-12.75's with 1.7x 60's.

PT4000 converter here. Stalling the converter up to 2800-3000 has netted us the best results with the MT Drag Radials. Any more and the tires break loose. Slicks might like a little more launch RPM but I don't have a set of those at the moment to try. My SI car has been running 7.50's to 7.60's all Summer in the 1/8th @ 89-90 MPH (7.50 best, 7.63 worst on a 90+ degree day) with 60's ranging from 1.59 to 1.63. I've got 3.90 gears in the rear now. I know that factors into what launch RPM works best so I just wanted to mention the gear as well.
