wanting better 60'

Blown89 · 02-03-2009, 06:38 PM

My car has 90/10 coilover struts with 175# springs full upr front end and upr pro series rear with anti rollbar no bushing all rod ends. I'm running a 306 with a holley 174 supercharger and a small shot of nos for an intercooler trans is a C4 with a ultimate converter with a stall of 2200 that feeds a 8.8 with a detroit locker with a 3.55 gear running 275/60/15 mt dr mounted on 10 wide welds . Leaving easy and not spraying till 3800 the car runs in the 6.30-6.40 eight mile at 109mph with a 60' in the 1.45 range. pinion angle is set at 1 degree down any more and i get bad vibration during decel.

Now for the problem whenever you leave hard (spray at 2200) the car will leave pull the front wheels and as long as they don't get any higher than a six inches off the ground it hooks any higher it blows the tires away (not just spin) the fact that it will leave and make it out thirty foot then blow the tires free has me puzzled.

Would an adjustable pinion snubber help the car don't have one?
