{"product_id":"57-3mm-billet-stainless-steel-supercharger-pulley","title":"57.3mm Billet Stainless Steel Supercharger Pulley","description":"The CTS Turbo Supercharger Pulley Bolt-On Style is precision-engineered for Audi 3.0T Gen 2 CREC engines, commonly found in late 2016+ models. This upgrade replaces the stock 63.25mm pulley with a smaller 57.3mm diameter unit, which increases the rotational speed of the supercharger. This results in higher boost pressure, with a notable increase from the stock 11psi to a steady 15psi held up to redline.\n\nConstructed from billet ASI303 stainless steel in Canada, this pulley boasts superior material quality and is finished with a Nitride coating for a long-lasting, OEM-like appearance. The design ensures that it does not increase stress or excessive wear on the supercharger or engine components. Installation hardware, including the required belt and bolts, is included with the kit.\n\nTo achieve the full performance benefits and ensure safe operation, this Supercharger Pulley Upgrade must be used in conjunction with \"Stage 2\" or \"Stage 2+\" performance ECU software. This software is essential for safely optimizing air-fuel ratios, timing, and boost pressure bleed-off, allowing for maximum power gains. Most aftermarket Stage 2+ tunes are compatible with this pulley kit.\n\nThis pulley is compatible with a range of Audi vehicles, including the B8.5 S4, S5, Q5, SQ5, C7.5 A6, A7, and late model Q7, all equipped with the 3.0T supercharged engine. Fitment includes models such as the Audi A6 C7 (2012-2018) 3.0T V6 Quattro, A7 C7 (2012-2018) 3.0T V6, Q5 B8 (2009-2017) 3.0T V6, Q7 4M (2017+) 3.0T, S4 B8 (2009-2016) 3.0T, S5 B8 (2009-2016) 3.0T, and SQ5 B8 (2014-2017) 3.0T.","brand":"CTS","offers":[{"title":"Default Title","offer_id":52662764994872,"sku":"CTS-HW-0333","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687496521.jpg?v=1784320725","url":"https:\/\/store.motormia.co\/products\/57-3mm-billet-stainless-steel-supercharger-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
