Integrated Engineering Product Description

*3.0 TFSI Performance Software and IE overdrive supercharger pulley (IEBAVJ1A) is sold separately and required in order for this pulley to yield a performance benefit.*

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 3 tune and intercooler 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.
