The 034Motorsport 3.0 TFSI Supercharger Crank Pulley Upgrades for the B8/B8.5 Audi S4/S5/Q5/SQ5 & C7 Audi A6/A7 are an easy way to increase supercharger rotational speed to provide more boost to your engine. These kits work with both the OEM supercharger pulley and the 034Motorsport 3.0 TFSI Supercharger Pulley Upgrade.
The 034Motorsport 3.0 TFSI Supercharger Crank Pulley Upgrades are machined from a single piece of 6061-T6 billet aluminum, and black anodized for an attractive finish resistant to corrosion. This design is over 62% lighter than the OE pulley, significantly reducing rotational weight and parasitic loss. These are lightweight, single-piece inner and outer pulleys, not a pulley "overlay" which adds rotational weight.
When used as the only pulley upgrade, these kits are 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.
