Upgrade your Volkswagen MK7 GTI, Golf R, or Audi 8V S3 with the NEUSPEED Power Pulley Kit, engineered to reduce parasitic drivetrain loss, improve throttle response, and help your engine rev more freely.
Designed specifically for EA888 Gen 3 MQB engines, the NEUSPEED Power Pulley Kit replaces the heavy factory crankshaft pulley with a lightweight, precision-machined underdrive pulley. By reducing rotating mass and accessory drive load, the engine uses less power to drive the alternator and air conditioning compressor, allowing more horsepower to reach the wheels while improving engine responsiveness.
Quick Fitment Overview
- Compatible with Volkswagen MK7/MK7.5 GTI, Golf R, Golf Alltrack, Golf SportWagen, and Audi 8V/8V.5 S3
- Lightweight underdrive crankshaft pulley kit
- 5–7 horsepower gain with 20% underdrive reduction
Product Description
The NEUSPEED Power Pulley Kit is engineered to reduce accessory drive losses by replacing the factory crankshaft pulley with a significantly lighter underdrive pulley. Using advanced CAD engineering and mass property analysis, NEUSPEED optimized the pulley design to reduce rotational inertia while maintaining reliable accessory operation. The result is improved throttle response, quicker engine revving, and measurable horsepower gains.
Manufactured from aerospace-grade 7075 aluminum, the pulley is hard anodized for exceptional durability and wear resistance. An exclusive heat-treated stainless steel wear ring is integrated into the pulley to prevent wear against the front crankshaft oil seal, providing long-term reliability that sets it apart from conventional lightweight pulleys.
The complete kit includes the lightweight crankshaft pulley, new crankshaft bolt, and correctly sized serpentine belt for a complete installation. Weighing only 13 oz compared to the factory pulley's 64 oz, the NEUSPEED Power Pulley Kit delivers noticeable improvements in engine responsiveness without sacrificing everyday drivability.
Best For: Drivers looking to improve throttle response, reduce rotational mass, and free up additional horsepower on the Volkswagen MK7 GTI, Golf R, and Audi 8V S3.
