Stage 1 Pulley Kit

The LG Motorsports Stage 1 Pulley Kit is an overdrive pulley system engineered to significantly enhance the performance of your LT4 engine. This kit aims to maximize power output by increasing the supercharger's rotation speed, leading to substantial gains in horsepower and torque. Specifically, it is designed to produce over 700 HP and 700 lb-ft of torque at the flywheel when paired with proper ECM re-calibration and tuning. The kit includes a comprehensive set of components necessary for this upgrade: an ATI LT1/LT4 dry sump torsional vibration damper, a 15% overdrive balancer pulley, all required pulley hardware, a heavy-duty Green Back Supercharger belt, a 100mm idler kit, and a crankshaft bolt. Installation is described as simple and should take approximately one hour. To achieve the advertised performance figures, proper ECM re-calibration is essential and is not included with this kit. However, no other components such as exhaust or fuel system modifications are required. The kit is designed to increase boost by 2.5 to 3 psi over stock and ensures no changes in drivability when properly tuned. This LG Motorsports 15% Overdrive Pulley Kit is specifically designed to fit 2015-2019 Corvette C7 Z06 models.
