Modified '02 Corvette: NA vs. Kenne Bell Blower
This particular C5 Corvette was equipped with a lightly upgraded LS1. The stock-displacement motor was augmented with a full complement of LS6 hardware, including heads and exhaust system. The stock cam was also ditched in favor of a mild LPE grind. In normally aspirated trim, the modified C5 motor produced 360 hp (the peak number shown is a spike that occurred at the end of the run) and 359 lb-ft of torque. After the installation of the Kenne Bell supercharger kit, the peak numbers jumped to 550 hp and 501 lb-ft of torque. Check out the huge torque gains throughout the rev range-all from just 7.5 psi of boost.
Stock '04 Z06 Corvette: NA vs. Kenne Bell Blower
The power gains on our stock LS6 were every bit as impressive as those of the modified LS1. This engine produced 372 hp and 364 lb-ft of torque in normally aspirated trim. Running 7.5 psi, these numbers jumped to 547 hp (again, ignore the spike number) and 522 lb-ft. What is most impressive about this supercharged LS6 is the immediate gratification that accompanies stepping on the throttle. Traction is scarce, and you'd better be pointing in the right direction when you finally put the spurs to it...well into third gear.
