The Corvette Stingray Z06 is one of the most potent cars that Chevy has ever produced for track work. The car comes with plenty of power under the hood, but there are some drivers always after more. If you are one of these drivers Corvette tuners Callaway Cars and Lingenfelter Performance Engineering have each unveiled their performance upgrades for the blown Z06.
Callaway pushes the Z06 to 757 hp and 777 lb-ft. of torque thanks in part to a new supercharger and intercooler. The company also offers a new hood with improved cooling and other parts. The package will cost $16,995(USD).
Lingenfelter offers a package with 720 hp and 730 lb-ft. of torque. This is achieved with a smaller pulley and new parts for the factory supercharger. This kit is much cheaper at $3,995 and includes a 12 month 12,000 mile warranty on the components. Both of these kits are sure to void your factory warranty.
