The 034Motorsport 3.0 TFSI Supercharger 207mm 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 the OEM supercharger pulley to create the proper dual pulley ratio required for 034Motorsport Dynamic+ Stage 2+ Tuning Software!

The 034Motorsport 3.0 TFSI Supercharger 207mm Crank Pulley Upgrade is machined from a single piece of 6061-T6 billet aluminum, and anodized black for an attractive finish resistant to corrosion. This design is 60% 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.
