On the dyno, power was definitely up across the board. The torque curve was broad, peaking at 433 lb/ft at 4,900 rpm. Horsepower was also up to an impressive 399 rear-wheel horsepower at 5,055 rpm. So we gained a solid 100 lb/ft of torque, and 90 horsepower at the rear wheels by installing the ProCharger HO system. With a fan in front of the intercooler to simulate driving at speed, or if our car had been bone stock when we began the installation, we have no doubt we could have achieved a solid 100 horsepower gain.
