ONE PULLEY - DUAL PULLEY POWER
This 207mm crank pulley delivers a supercharger ratio similar to a traditional dual pulley setup that uses a combined smaller 57.5mm supercharger pulley with a larger 188mm crank pulley. This pulley allows the use of a dual pulley ECU tune without the need to purchase multiple pulleys and press off/on a new supercharger pulley for a faster and easier installation process.
If you already have a smaller supercharger pulley installed, purchase the 188mm crank pulley part number IEBAVJ7 to go dual pulley.
| PULLEY | SC PULLEY SIZE (MM) | CRANK PULLEY SIZE (MM) | FINAL RATIO |
| STOCK PULLEYS | 63.20 | 162.25 | 2.5672 |
| SINGLE PULLEY (SC PULLEY) | 57.5 | 162.25 | 2.8217 |
| DUAL PULLEY (SC + CRANK PULLEYS) | 57.5 | 188 | 3.2695 |

CRANK PULLEY & DAMPER
This complete one-piece pulley replaces both the crank pulley and factory engine damper in one unit. Replacing the engine damper provides increased reliability and protection from a possible faulty stock engine damper that is known to separate, causing costly engine damage.
LIGHTWEIGHT DESIGN
Weighing in at only 2025 grams, IE engineers have produced a robust pulley while trimming as much fat as possible without risking the structural design. The aluminum construction is 49% lighter than the stock setup, reducing rotating mass, resulting in faster engine revs and less parasitic loss.
MADE IN THE USA
This one-piece design delivers significant power and is a vital link that holds your engine and supercharger together. Enjoy the peace of mind knowing your pulley is 100% in-house designed and CNC machined from top-of-the-line sourced aluminum alloy followed by an extensive quality-control process.
QUALITY FINISH
The 6061-T6 aluminum pulley is finished with an attractive black anodized finish. The anodizing process offers superior protection against corrosion while retaining the proper installation clearances. After applying the coating, the alignment marks, part number, and logo are laser etched to guarantee long life and a fantastic look.
INSTALLATION
Installing your new pulley is straightforward and hassle-free with the proper tools. Although installation requires using a grinder to remove an unused small metal post from the engine block, the installation is typically easier than press-fitting on a supercharger pulley.
Install time around 2-3 hours

*2016-2018 A6 & A7 CREC 3.0T engines do not have compatible IE software support for 207mm lower crank pulley. IE single pulley CREC tunes safely produce typical dual pulley ratio numbers on this platform. Running 207mm or dual pulley ratio 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.
