For more information, visit www.P65warnings.ca.gov.The APR 187mm Supercharger Crank Pulley (MS100133) is a high-performance drive upgrade for the Audi 3.0 TFSI engine. By increasing the outer diameter of the crankshaft pulley from the stock ~162mm to 187mm, this upgrade effectively over-drives the supercharger, spinning it 15.4% faster than the factory configuration. This results in a substantial increase in boost pressure, delivering massive gains in horsepower and torque across the entire powerband when paired with the appropriate Stage 2+ software.
Unlike replacement pulleys that remove the essential vibration damping of the engine, the APR design is a bolt-on solution that installs directly onto the face of the factory harmonically balanced unit. Precision CNC-machined from lightweight billet aluminum, the pulley features weight-saving pockets to minimize rotational inertia and is finished in an anodized and E-coated black for long-term durability. This "Stage 2 Dual Pulley" capable component is the key to unlocking the maximum potential of the 3.0T platform.
Features:
- Increased Boost: Over-drives the supercharger by 15.4% to provide significant performance gains throughout the RPM range.
- Retains Harmonic Balancer: Bolts onto the existing factory unit to preserve engine balance and protect internal bearings.
- Billet Aluminum Construction: Lightweight, CNC-machined design with weight-saving pockets for reduced rotating mass.
- Stealth Aesthetics: Features an anodized and E-coated factory black finish for a discreet look and corrosion resistance.
- Dual Pulley Ready: Can be used with the factory supercharger pulley or combined with an APR drive pulley for maximum boost levels.
- Complete Hardware: Includes new high-strength crank pulley bolts for a secure installation.
Product Contains:
- (1) 187mm Billet Aluminum Crank Pulley Ring
- (1) Set of High-Strength Mounting Bolts
Important Installation Note: This upgrade requires specific APR Stage 2 (Dual Pulley) ECU software to manage the increased boost levels and protect the engine. Additionally, a new supercharger belt is required: use RS100003 with a stock drive pulley, or RS100002 when paired with an APR supercharger drive pulley.
