At 57.70mm in diameter, the 034Motorsport CREC 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 Stage 2 or Stage 2+ Performance Software.

034Motorsport's Supercharger Pulley Upgrade is meant for use with CREC Stage 2 or Stage 2+ Performance Software and is engineered to keep the Eaton TVS 1320 Supercharger within its maximum recommended supercharger speed with a 7,400 RPM redline.

Please Note: This Supercharger Pulley Upgrade must also be paired with the 034Motorsport Billet CREC Supercharger Clutch Delete Kit.

Included is the properly sized Dynamic+ Supercharger Belt for this pulley upgrade when used with the factory lower crank pulley. Pairing this pulley upgrade with the 179MM will require the 1290mm Dynamic+ Supercharger Belt. Pairing this pulley upgrade with the 190MM crank pulley will require the 1310mm Dynamic+ Supercharger Belt.

CREC Stage 2 and 2+ require the Supercharger clutch to be deleted, so if you are purchasing this pulley upgrade to go to Stage 2 or 2+ and have yet to delete the clutch, add one of our Steel or Titanium CREC Clutch Deletes to your order.
