Supercharger Pulley Upgrade:

At 57.70mm in diameter, the 034Motorsport 3.0 TFSI Supercharger Pulley is significantly smaller than the factory unit in order to increase the drive ratio of the supercharger. Spinning the supercharger faster yields increased boost pressure throughout the RPM range, resulting in increased horsepower and torque throughout the powerband when paired with 034Motorsport Stage 2+ Performance Software.

190MM Crank Pulley Upgrade:

The 034Motorsport 3.0 TFSI Supercharger 190mm Crank Pulley Upgrade for the Audi B8/B8.5 S4/S5/Q5/SQ5, C7 A6/A7, and D4 A8 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.

Features:

• Machined from a Single Piece of 6061-T6 Billet Aluminum
• Black Anodized with Laser Engraving for a Durable Finish
• Reduced Parasitic Loss - 62% Lighter than Stock
• Complete Inner and Outer Pulley, Not Just a Pulley "Overlay", Which Adds Weight
