last time I was at the track I was launching 4wd in 2nd gear at about 2500 rpm's I was rolling the clutch. I think my best 60 foot was 2.9 though...

I WILL SIT THERE AT THE STAGING BEAMS REV TRUCK TO ABOUT 2200-2500 AND WHEN THE LAST YELLOW LIGHT ON THE BOTTOM GOES OUT I DUMP THE CLUTCH.... MADE SOME PRETTY GOOD TREES ON IT BUT IF YOU DECIDE TO DO THE CLUTCH DUMP THING IN 4X4 HOLD YOUR HEAD TO THE HEADREST BECUASE I THOUGHT I WAS GOING TO SNAP MY NECK WHEN IT JUMPED OUT OF THE HOLE

rev the truck up and then let the clutch out like a normal person instead of dumping it... each time you do this its about the same amount of wear as 20,000 normal driving miles on your clutch.
