While using only 20 percent of Banks' new dyno's capacity, the PowerPack'd Dodge belted out an impressive 650 lb-ft at a mere 1,500 rpm. That was in Third (direct) gear with the torque converter locked. From 2,600 rpm on up, the seriously awakened Cummins put over 300 hp on the dyno's twin 20-inch rolls. That's more than 100 extra Clydesdales, at 200 rpm less than stock. Stout as those numbers are, they barely tickled the new Mustang dyno's 1,500hp capacity. Two large fans pump 60-mph air into the intercooler and help the vehicle keep its cool.
