There is no way to answer this question. It all depends on the car. I used to street race Pontiac A-bodies (GTOs) in the late '70s, and the first time I got into an 'incident", I did just what my older friend and mentor did with his '68 Chevelle. I wound up my GTO to about 3800 rpm and dumped the clutch. Fortunately the car was factory with 3.90 gears (and not a higher ratio), and I didn't grenade the entire thing...I only destroyed the transmission. I didn't take into consideration that my friends Chevelle had the 396 removed and a 13.1, 327 cid with 4.56 gears was installed specifically for racing on the street. In my situation, Pontiac 400s make incredible amounts of torque just off idle, and I learned the hard way that all I needed to do with that cars weight and gearing was to bring the car just off idle, let out the clutch normally, and as smoothly as possible floor it. That way I avoided wheel hop, and shocking the drivetrain, and the second that the weight was rolling, it would hook and get gone. Sure the Chevys would jump me off the line, (which really bothered me at first), but I'd blow by them in 3rd like they were standing still.
Your combination will dictate how you launch. In my Dart; (Superstock Hemi 4-speed, 340 stroker, 4.56 spool, Superstock springs, 2900-ish lbs) it is much differrent. Rev high, burn the clutch, the second you feel hookup, dump, and go. If you race a 4-speed you will replace MANY clutches. They are like oil... Used and replaced.
