What RPM are you launching at?

Curious as to how hard most of you are leaving. With a twin disk clutch, 3" drivshaft, beefed up tranny, and moser 9" i think i can leave pretty hard.The highest ive left is 4800 rpm.

Best time I've gotten is a 11.8 by feathering the clutch out at around 3k. Using M/T ets. Dropped the clutch and blew the gears apart - so no more of that for now lol. What rear gears, DRs or streets, motor specs - It usually will just come down to practice to see where the car likes to run. Might be 2k or 4k - every car will be different depending on the setup. I'd say start lower and increase as you go and see how the times react.

5500-6000 with a quick slip of the clutch. It has to be a really quick slip, and has to be right or it equals a bad bog, or bad wheel spin. I was cutting pretty consistent 1.68's with MT ET Street radials and a Moser 9" and TruTrac.

When I would lower the launch RPM to 3500ish, it would bog badly out of the hole with MT ET's on. Those tires will hook when given a decent burn out. Best time was a 11.91, with hitting the limiter on at least one gear at 117 MPH if I remember right.

Footbrake to 3k, drop the hammer on 3rd yellow.

With my street tires,I'd just idle at the line and mash the gas on the 3rd yellow,anything more and major wheel spin.

Now that I got some DR's i'm going to try and foot brake it to3000rpm,launch and see what happens
