Audi A6 Pulley Kit - APR - Dual Pulley with Belt - Black - `15-`18. A complete dual-pulley solution for the C7 3.0 TFSI, engineered to increase supercharger speed and provide headroom for performance tuning.

This kit pairs APR’s 57.75 mm supercharger drive pulley with a 187 mm crank pulley. The drive pulley reduces the factory ~63.25 mm diameter for about a 9.5% increase in blower speed, while the crank pulley increases the factory ~162 mm diameter for about a 15.4% gain. Combined, the supercharger turns roughly 26.4% faster than stock. The drive pulley is CNC-machined from billet stainless steel and e-coated black; the crank pulley is lightweight billet aluminum with a black anodized finish and includes new crank bolts. The system retains the factory harmonic balancer and comes with the correct belt. Software is sold separately and required to maximize output; to fully take advantage of the dual-pulley airflow, the APR Ultracharger Throttle Body Upgrade is necessary.
