Lingenfelter is world-renowned for pushing the limits on horsepower and their new engine package for the 2009-2011 Cadillac CTS-V (and new CTS-V Coupe) is no exception to the rule. Providing a turnkey package to CTS-V owners, Lingenfelter Performance Engineering offers 623-rwhp and 617 lb-ft of torque at the wheels in a manual transmission CTS-V.
The performance package is as comprehensive as one can get which includes removing the stock powerplant from the vehicle and overhauling it for extreme power. Much of the work is done in the head, with Lingenfelter’s CNC port & polish while swapping in new valves, valve springs and retainers. Helping aid in producing high end horsepower is Lingenfelter’s GT9 camshaft.
Lingenfelter then focuses on providing additional fuel to go with the extra boost thanks a 2.55-inch diameter steel supercharger drive pulley. New injectors are installed and the entire package is tested to perfection on a dyno with extensive ECM tuning.
The complete package comes with Lingenfelter’s 2 year, 24,000-mile warranty.
