Running stock rear suspension, stock 3.27 rear end and stock 3650, mt 275 50 15's s/s this past weekend in my twin turbo mustang. Sure the trans is going to blow up soon behind 650 hp, but I was rather impressed with my 1.380 60' time. It seems if I can replace the trans with a t56 viper with similar gearing, I should be able to replicate? At this power level, I want to make it last, not necessarily change any of the components. Cutting that kind of a time with no subframes, upper or lower control arms makes me wonder why I'd make any changes?
