Show original supplier description
The Lingenfelter press-on steel 11-rib 2.60-inch diameter pulley is engineered to increase supercharger speed for enhanced performance on C6 ZR1 LS9 models. This pulley provides a 19% supercharger overdrive, pushing the supercharger speed to 18,300 RPM when the engine is at 6,500 RPM, significantly higher than the stock LS9 supercharger speed of 15,400 RPM. Designed for direct fitment with the ZR1 Supercharger snout or front cover, this 10-bolt pulley utilizes the stock belt when paired with the Lingenfelter 100 mm idler pulley (L250130309). Alternatively, when used in conjunction with the Lingenfelter 14% Overdrive Harmonic Balancer, a 2160 mm 11-rib belt (11PK2160) and stock idlers are required. It is important to note that modifications listed on this page require recalibration of the factory ECM to ensure proper operation and engine management. Lingenfelter advises against exceeding 23,000 RPM on the LS9 supercharger, a limit that can be reached when using a 2.38” pulley combined with their 14% overdrive damper.
