Integrated Engineering Audi 3.0T B8 B8.5 C7 C7.5 Supercharger Pulley Upgrade 4-Bolt Style (S4, S5, A6 & A7)
The IE supercharger pulley for late 4 bolt style 3.0T V6 Audi engines extracts more power from your supercharger by spinning the unit 7% faster than stock, resulting in higher boost levels. Paired with a Stage 2 Tune, you can expect gains over 25 horsepower on pump fuel.
- Increases supercharger RPM by 7%
- Increases supercharger boost levels
- CNC machined from billet steel
- Inside bore precision honed at IE
- Zinc plated to ensure no rust
- Replaces stock pulley on 4 bolt Eaton TVS 1320 Superchargers
- Engineered in-house using CAD modeling and FEA analysis
Small Pulley, More Boost!
The IE 4 Bolt Style Supercharger Pulley is designed for many late-model Audi 3.0T Supercharged engines that use the non-press-fit updated bolt-on style of supercharger pulley found on many 2016+ B8/B8.5 S4, S5, Q5, SQ5, C7/C7.5 A6, A7, and Q7 models. The pulley functions by increasing the supercharger RPM throughout the full powerband. The IE pulley is 58.8mm in diameter, making it one of most aggressive and powerful on the market.

- Integrated Engineering Audi 3.0T B8 B8.5 Intake (S4 & S5)
- Heat Exchanger Upgrade
- Audi B8/B8.5 S4 S5 Q5 SQ5 2016+
- Audi C7/C7.5 A6 A7 Q7 2016+
Does not fit early press-fit style S4, S5, A6 Q5/SQ5, and Q7. These engines are easily identified because the supercharger pulley has no bolts to attach it to the supercharger. For the press fit style models, please look at the Integrated Engineering Audi 3.0T B8 B8.5 C7 C7.5 Supercharger Pulley Upgrade Press-Fit Style (S4, S5, A6 & A7).
Installing the 4 bolt style supercharger pulley is rather easy for the casual enthusiast and only requires basic tools and can be completed in a matter of hours in most cases.
