IE is excited to release upgraded overdrive pulleys for 3.0T Engines. The overdrive supercharger pulley increases the charger RPM by 10%. When adding the overdrive crank pulley the supercharger is increased by another 16%, to 26% in total. This translates to higher boost levels and more power!

The supercharger 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. 

Fitment Note: Does not fit 2016 S4, 2015+ A6 and Q5 / Q7. These engines are easily identified because the supercharger pulley has 4 bolts to attach it to the supercharger.

Installation Note: You will need to remove the stock supercharger pulley in order to install an IE unit. You will need a 3.0T Pulley Puller Kit and a toaster oven or hot plate to heat the pulley for installation. IE's full install guide is located here: (LINK COMING SOON). Due to the hardware and tools required, professional installation may make more sense for casual enthusiasts.
