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.     

PULLEY SPECIFICATIONS

WHAT'S INCLUDED & WHAT'S SOLD SEPARATELY

The following items are included:

• 1X IE Overdrive Crank Pulley

• 1X Overdrive Serpentine Belt

• 8X Overdrive Crank Pulley Bolts

The following items are not included but required:

INSTALLATION

The Crank Pulley installs over the stock crankshaft damper which is a relatively simple process. However, and mounting boss will need to be cleared in order to allow sufficient space for the serpentine belt. A grinder or Dremel tool will be required for this process. Our full install guide is located HERE.

*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.
