If the factory 556 horsepower CTS-V was not enough to feed your performance addiction, then Lingenfelter’s CTS-V upgrade could be your fix. Mibz.com featured a story on this package, which is capable of producing over 700 horsepower at the crank; in other words you should probably put some money aside for impound fees, bail and a good attorney.
Lingenfelter uses their GT9 ZR1 supercharger cam and ported LSA heads. The cylinder heads are reworked through CNC porting and polishing, and valve upgrades. Along with the cam and headwork, the supercharger receives a different pulley and a port and polish job on the snout. One of the benefits of this package is the ability to make a generous amount of power while keeping the boost at a safe level. Along with the performance enhancements this package comes with a two-year/24,000 mile warranty.
Although the $11,245 price tag may sound steep, just keep in mind that catastrophic engine failure can get pretty pricey these days. Lingenfelter includes professional installation, tuning, dyno testing and again, a two-year warranty. With dyno results of 623 horsepower and 617 ft-lbs of torque to the tires, there is no way this car will avoid track time and some stop light acceleration tests. Consider the warranty a form of insurance and drive it for all it’s worth.
