Audi Q7 Crank Pulley - APR - Supercharger Crank Pulley Upgrade 187mm - Black - 2011–2015. A bolt-on overdrive crank pulley that increases supercharger speed for a more responsive 3.0 TFSI with proper tuning.

APR’s 187mm crank pulley bolts to the factory harmonically balanced hub, increasing diameter from ~162mm to ~187mm for roughly 15.4% more blower speed. CNC-machined from lightweight billet aluminum, anodized black, and supplied with new crank bolts, it is built for reliability and consistent performance. To maximize output, APR Stage II ECU software is recommended. A longer belt is required: use RS100003 with the factory supercharger drive pulley, or RS100002 with the APR drive pulley.
