- 16% additional increase in supercharger speed
- 26% Increase supercharger speed when used with IEBAVJ1A
- Retains the OEM damper to ensure crankshaft safety
- IE overdrive crank pulley diameter is 188mm (stock 162.25mm)
- Lightweight anodized aluminum construction
- Includes belt and all replacement hardware
WHAT DOES A CRANK PULLEY UPGRADE DO?
The IE Overdrive Crank Pulley Upgrade is designed to work in hand with the IE Overdrive Supercharger Pulley Upgrade Kit. When installed together the charger speed will increase by 26% resulting in higher boost levels and more power. Also required for proper operation is a Stage 2 Dual Pulley Tune and heat exchanger upgrade. Healthy power gains will be realized from running a dual pulley setup, however, gains will vary depending on the ECU tune used. This pulley also removes all supercharger torque from the OEM Damper unit, greatly decreasing the chances of damper failure.

*2016-2018 A6 & A7 CREC 3.0T engines do not have compatible IE software support for this lower crank pulley. IE single pulley CREC tunes safely produce typical dual pulley numbers on this platform. Running dual pulley setups may cause supercharger clutch failure on CREC engines and is not recommended. CREC engine is also found in ROW (rest-of-world) markets on some late-model S4 & S5 3.0T as well. CREC engines are easily identified as the supercharger pulley has 4 bolts to attach it to the supercharger instead of a press-fit style.
