The IE supercharger pulley for 3.0T V6 Audi engines is a great mod to extract more power form your supercharger. Capable of up to 492HP on it's own with a IE stage 2 single pulley tune, or combine with IE 188mm crank pulley (IEBAVJ7) (Stage 2 dual pulley) for up to a massive 548HP! These power gains are achieved by spinning the supercharger unit significantly faster than stock for higher boost levels with pulleys and proper ECU tuning.   


  • Increases supercharger RPM by 10% for single pulley
  • Combine with IE 188mm crank pulley for 26% SC RPM increase
  • Increases supercharger boost levels for single & dual pulley tunes
  • CNC machined from billet steel
  • Inside bore precision honed at IE  
  • Zinc plated to ensure no rust
  • Replaces stock pulley on Eaton TVS 1320 Superchargers
  • Engineered in-house using CAD modeling and FEA analysis

    *2016-2018 A6 & A7 3.0T engines and some late model ROW (non-US) S4/S5 are equipped with a different engine (CREC) is not compatible with IE press-on supercharger pulley. Please see our 3.0T CREC 4-bolt supercharger pulley for these model years. CREC engines are easily identified as the supercharger pulley has 4 bolts to attach it to the supercharger instead of a press-fit style.

     WARNING: Warranty VOID if a non-IE puller tool (part numberIEBAVJ4) is used to remove your pulley. Using any other tool other than the IE unit will DEFINITELY destroy your pulley. DO NOT ATTEMPT TO REMOVE IE PULLEY WITHOUT IE BRAND PULLER TOOL.
