Unitronic is pleased to announce the release of its Stage 3 Crank Pulley Upgrade Kit for the 3.0TFSI* engines. Featuring an impressive increase to 493 HP/441 lb-ft of torque, Unitronic’s Stage 3 Crank Pulley Upgrade Kit includes its 187 mm Crank Pulley, 7PK1300 Belt, and most importantly, its Stage 3 Dual Pulley Performance Software calibration.

This can be purchased as a Cmplete Kit for customers with no software and no pulley upgrades. Unitronic's Stage 3 Dual Pulley Performance Software calibration is engineered specifically for use with both its Supercharger Drive and Crank Pulleys to ensure maximum performance is achieved while maintaining complete OEM-like reliability and drivability.

  • Unitronic Supercharger Pulley
  • Unitronic 187mm Crank Pulley
  • 6061-T6 CNC-machined Aluminum
  • Black anodized finish
  • TDC marking for easy install
  • 7PK1300 belt
  • Genuine Audi crankshaft bolts included
Unitronic strongly recommends combining its Stage 3 Dual Pulley Upgrade Kit with an effective Supercharger Cooling System/Heat Exchanger Upgrade to ensure maximum performance can be achieved and can be achieved repeatably. Through development and testing, Unitronic observed up to a 30 hp variance in engine output based on operating conditions, while using the stock (OEM) heat exchanger, as a result of increased intake air temperatures and associated temperature-based corrections to boost and ignition timing.

*Available for B8/B8.5 S4/S5 and SQ5 models only currently. Peak engine output will vary based on the the maximum engine speed limit.
