WHAT DOES A CRANK PULLEY UPGRADE DO?

The IE Overdrive Crank Pulley Upgrade is designed to work in-hand with the IE Overdrive Superchager 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. ????
