034Motorsport 3.0 TFSI Supercharger 190mm Crank Pulley Upgrade, B8/B8.5 Audi S4/S5/Q5/SQ5 & C7 Audi A6/A7

Description Product Description The 034Motorsport 3.0 TFSI Supercharger 190mm Crank Pulley Upgrade for the B8/B8.5 Audi S4/S5/Q5/SQ5 & C7 Audi A6/A7 is an easy way to increase supercharger rotational speed to provide more boost to your engine. This kit works with both the OEM supercharger pulley and the 034Motorsport 3.0 TFSI Supercharger Pulley Upgrade. The 034Motorsport 3.0 TFSI Supercharger 190mm Crank Pulley Upgrade is machined from a single piece of 6061-T6 billet aluminum, and black anodized for an attractive finish resistant to corrosion. This design is 62% lighter than the OE pulley, significantly reducing rotational weight and parasitic loss. This is a single piece inner and outer pulley, not a pulley “overlay”, which adds rotational weight. When used as the only pulley upgrade, this kit is an easy upgrade that can be used with the Dynamic B8/B8.5 3.0 TFSI Performance Software Stage 2 tune. When used in conjunction with the 034Motorsport 3.0 TFSI Supercharger Pulley Upgrade, the Dynamic B8/B8.5 3.0 TFSI Performance Software Stage 2 tune is recommended.
