Before installing the Kenne Bell blower, we ran the stock LSA to establish a baseline. Running through the automatic transmission, the supercharged 6.2L produced peak numbers of 466 hp and 474 lb-ft of torque (SAE). Some quick math here tells us that 466 rwhp divided by 580 flywheel hp means the automatic drivetrain is soaking up 20-percent of the available power. Peak boost pressure registered during the baseline runs with the Eaton supercharger was 7.9 psi. After installation of the Kenne Bell twin-screw supercharger, the boost pressure jumped to 13 psi, where the LSA produced 570 rwhp (approximately 684hp flywheel) and 526 lb-ft of torque. Who can argue with 100 extra horsepower?
