Description
Integrated Engineering is excited to release upgraded overdrive pulleys for 3.0T engines found in B8/B8.5 S4, S5, Q5, SQ5, C7/C7.5 A6, A7, and Q7 models. The overdrive supercharger pulley increases the charger ROM by 10%. When adding their overdrive crank pulley in unison (IEBAVJ3), the supercharger is increased by another 16%, to 26% in total. This translates to higher boost levels and more power!
The pulley functions by increasing the supercharger RPM throughout the full powerband. At redline, supercharger speed is increased by 1800 RPM. The IE pulley is 57.50mm in diameter, making it one of most aggressive and powerful on the market.
Features:
- Increases supercharger ROM by 10%
- Replaces stock pulley on Eaton TVS 1320 supercharger
- Engineered in-house using CAD modeling and FEA analysis
- CNC machined from billet steel
- Inside bore precision honed at IE
The following items are included:
1X IE Overdrive Supercharger Pulley
The following items are not included but required:
- Stage 2 tune (IESOCGJ2)
- 3.0T Supercharger Pulley Puller Tool (IEBAVJ4)
