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. { "__shgImageElements": { "uuid": "s-4d0abc44-5f4b-4ca8-898e-a42280d668c9" } } { "__shgImageElements": { "uuid": "s-2dafda65-3664-48bf-9625-eb2afed95d80" } } 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.   { "__shgImageElements": { "uuid": "s-1e1fbca1-e282-4fe8-8fbb-9aaca5cf4649" } } INSTALLATION Installing your new pulley is straightforward and hassle-free with the proper tools.

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.
