Dynojet test results are: 552 rear wheel hp (approx. 636 hp at the flywheel) and 474 rear wheel torque (approx. 545 lb-ft torque at the flywheel). This is a significant boost over the 500 stock horsepower and 470 torque at the flywheel (136 hp and 75 ft/lbs of torque improvement). Watch it pull multiple consistent runs on the dyno here. Turn your speakers and headphones up for this.
