APR MS100133 Supercharger Drive and Crank Pulley Upgrade for 3.0 TFSI

The APR MS100133 is a performance-engineered crank pulley designed specifically for 3.0 TFSI supercharged engines. This precision-manufactured pulley provides a straightforward path to significantly increased boost pressure and power output when paired with appropriate ECU tuning.

Key Features:

• 187mm diameter bolt-on crank pulley increases supercharger speed by 15.4%
• Retains factory harmonic balancer for engine protection and reliability
• Factory black finish with anodized and E-coated surface for durability and corrosion resistance
• Direct bolt-on installation with no permanent modifications required
• Delivers substantial torque and horsepower gains when used with APR ECU calibration

This pulley upgrade is an essential component for enthusiasts seeking maximum performance from their 3.0 TFSI platform. By spinning the supercharger faster, it generates increased boost pressure throughout the RPM range, resulting in dramatic improvements in acceleration and overall engine output. The retention of the harmonic balancer ensures proper crankshaft vibration dampening, maintaining engine longevity even at elevated performance levels.
