When we last left Lethal Performance’s latest GT500 project we had run the gamut of bolt-on modifications (“Let It Eat,” Nov. ’12, p. 74). The results were quite impressive, as the car put down more than 740 horsepower at the tire with the stock blower and more than 830 rwhp on the sauce. With UPR Products’ Jeremy Martorella rowing the gears, the combination yielded a 9.77-second e.t. at 148.80 mph on the Palm Beach International Raceway drag strip. After the built motor and big blower Jeremy ripped off a 9.39 at 147.63 mph.
