Show original supplier description
The Lingenfelter supercharger pulley upgrade kit is engineered to boost the performance of the 2009-2013 LS9 Corvette ZR1 supercharged engine. This kit directly enhances output, aiming to surpass the factory's 638 horsepower and 604 lbs ft of torque by safely increasing boost levels and supercharger RPM. Lingenfelter's testing indicates that this pulley upgrade can achieve approximately 680 BHP and 660 lbs ft of torque. The kit achieves this by overdriving the supercharger by 19% using a 2.60-inch diameter, 11-rib steel drive pulley. It also includes a 100mm aluminum double-bearing idler assembly and a Lingenfelter LS9 solid supercharger isolator coupling, along with all necessary installation hardware. Installation of this pulley kit necessitates ECM programming to adjust the electronic control module's overboost limits. The stock serpentine belt is retained for compatibility.
