|
Still with a stock exhaust system and only 3 psi more boost, the car showed a 40- to 75-hp gain from 4900 rpm-on, with peak gains of 74.9 hp at 6100 rpm, and 66 lb-ft of torque at 5850 rpm over stock. Keep in mind the baseline was done with the car relatively cool, and at 13 psi, the car had been on the dyno non-stop for hours without shutting it off. View Related Article
