One piece aluminum driveshaft might help? Some skinny/lighter tires/wheels up front? Test pipes for the exhaust(eliminate the cats)? Headers might add a few more HP. Definetly a stall and gears would help. If we could pull some 1.5-1.6 60ft it would happen.
N20 is the cheapest easiest way, without the question of running lean on the stock injectors, to go deep into the 11's regardless of DA. Atmosphere in a bottle.
