720 HP Z06 Corvette Upgrade Kit

The Lingenfelter 720 HP Z06 Corvette Upgrade Kit is a performance enhancement package designed for the C7 Z06 Corvette, leveraging Lingenfelter Performance Engineering's (LPE) established 720 HP configuration. This kit aims to provide a proven combination of components, suitable for both professional installation and experienced DIY enthusiasts, to significantly boost the vehicle's power output. This comprehensive kit is engineered to deliver substantial gains, producing 720 HP and 730 lb-ft of torque at the flywheel. Engine dyno testing has verified these figures, showing 720 HP at 6100 RPM and 730 lb-ft of torque at 3750 RPM, along with an approximate 2.5 psi boost increase to reach 13 psi. The components included are designed to work harmoniously, featuring a Lingenfelter/ATI LT1/LT4 dry sump torsional vibration damper, a 15% overdrive 9.2-inch supercharger drive damper pulley, pulley fasteners, a supercharger belt, a 100mm idler kit, a low-restriction air filter, and a crankshaft bolt. Aluminum construction and a black pulley finish are noted specifications. It is crucial to note that an ECM calibration is required for this kit to achieve the specified performance levels, but this calibration is not included. Lingenfelter states that, aside from the ECM tuning, no other components are necessary to reach the advertised performance figures. Testing was conducted on an otherwise stock vehicle, including its stock exhaust and fuel system. The installation process involves a specific torque specification for the crankshaft bolt: 59 ft lbs plus 200 degrees, applied with red loctite.
