APR MS100139 Supercharger Drive Pulley 57.75mm 3.0 TFSI Gen 2

The APR MS100139 is a high-performance supercharger drive pulley engineered for 3.0 TFSI Gen 2 engines. This precision-machined 57.75mm pulley is designed to increase supercharger rotational speed by 9.5% over the stock pulley, delivering substantial gains in both horsepower and torque when paired with APR pulley-specific software tuning.

Key Features:

• 57.75mm diameter for optimized supercharger overdrive
• Direct bolt-on installation for Gen 2 3.0 TFSI applications
• Anodized and E-coated factory black finish for durability and corrosion resistance
• 9.5% increase in supercharger speed for significant power gains
• Requires APR pulley-specific ECU software for proper calibration and maximum performance
• Precision-engineered for proper belt alignment and tension

This pulley modification is one of the most effective power upgrades for supercharged 3.0 TFSI engines, providing immediate boost pressure increases across the entire RPM range. Professional installation and APR software tuning are required to achieve optimal results and ensure safe air-fuel ratios under increased boost conditions.
