DUAL PULLEY UPGRADE
This 188mm crank pulley is designed to be combined with an IE 57.5mm supercharger pulley (IEBAVJ1C) to upgrade your existing single pulley setup for stage 2 dual pulley tunes.
If you do not have a upgraded supercharger pulley and want to jump straight to Stage 2 double pulley power, the 207mm crank pulley IEBAVJ6 can be used instead without the need to purchase a smaller press-on SC 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 |
| DUAL PULLEY (207MM CRANK PULLEY) | 63.20 | 207 | 3.2753 |
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 1613 grams, IE engineers have produced a robust pulley while trimming as much fat as possible without risking the structural design. The aluminum construction is 59% 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 extensive quality-control.
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.
Install time around 2-3 hours

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