how are you launching the car? i see the 60' is ok but after looking at the 330' numbers it looks like the car might have bogged when the rpms came all the way down.
for instance i have run a quicker ET spinning to a 1.89 60' vs a 1.82 dumping the clutch at 5k and dead hooking because the clutch will slip a little at first and the rpms will slowly fall but they eventually fall to 3500 and the car falls on its face. so even tho the 60' was quicker the 330' and up was slower.
