This results in a healthy bump in horsepower and torque across the entire RPM range with the supercharger operating at a higher rate of speed. The pulley is CNC machined from billet stainless steel, e-coated black for an OEM appearance and is bolted to the factory supercharger unit.APR's Supercharger Crank Pulley Upgrade increases the diameter of the factory pulley from ~162mm to ~187mm, which in turn spins the supercharger ~15.4% faster. This results in a larger bump in horsepower and torque across the entire RPM range, as the supercharger is spinning at an even higher rate of speed. The pulley retains the factory harmonically balanced crank pulley and bolts on top of the existing unit. It is CNC machined from light weight billet aluminum with weight saving pockets throughout. It has an anodized black finish and includes new crank pulley bolts.Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning ~26.4% faster than stock. This speed was chosen after extensive engine and chassis dyno testing with various pulley sizes and supercharger speeds. The result is an even higher horsepower and torque gain across the entire RPM range. However, at the airflow levels achieved with a dual pulley setup, maximum power is severely restricted by the factory throttle body unit. The APR Ultracharger Throttle Body Upgrade is necessary to take full advantage of the dual pulley configuration, and is available in platform specific variations for the B8\/B8.5 A4\/A4\/S4\/S5, Q5\/SQ5 and C7 A6\/A7.Belt IncludedSoftware sold separately\u003c\/p\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003ePlease note, specific software is required to maximize output with this product.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2015 Audi A8 Quattro Base\u003c\/li\u003e\n\u003cli\u003e2015–2016 Audi A8 Quattro L TDI\u003c\/li\u003e\n\u003cli\u003e2015–2018 Audi A8 Quattro L\u003c\/li\u003e\n\u003cli\u003e2016 Audi A6 Quattro TDI Premium Plus\u003c\/li\u003e\n\u003cli\u003e2016 Audi A6 Quattro TDI Prestige\u003c\/li\u003e\n\u003cli\u003e2016 Audi A7 Quattro TDI Premium Plus\u003c\/li\u003e\n\u003cli\u003e2016 Audi A7 Quattro TDI Prestige\u003c\/li\u003e\n\u003cli\u003e2016–2018 Audi A6 Quattro Premium Plus\u003c\/li\u003e\n\u003cli\u003e2016–2018 Audi A6 Quattro Prestige\u003c\/li\u003e\n\u003cli\u003e2016–2018 Audi A7 Quattro Premium Plus\u003c\/li\u003e\n\u003cli\u003e2016–2018 Audi A7 Quattro Prestige\u003c\/li\u003e\n\u003cli\u003e2017 Audi A6 Quattro Competition\u003c\/li\u003e\n\u003cli\u003e2017 Audi A7 Quattro Competition\u003c\/li\u003e\n\u003cli\u003e2017–2019 Audi Q7 Premium\u003c\/li\u003e\n\u003cli\u003e2017–2019 Audi Q7 Premium Plus\u003c\/li\u003e\n\u003cli\u003e2017–2019 Audi Q7 Prestige\u003c\/li\u003e\n\u003cli\u003e2018 Audi A6 Quattro Premium\u003c\/li\u003e\n\u003cli\u003e2018 Audi A6 Quattro Sport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdl\u003e\n\u003cdt\u003eManufacturer part number\u003c\/dt\u003e\n\u003cdd\u003eMS100185\u003c\/dd\u003e\n\u003cdt\u003eUPC\u003c\/dt\u003e\n\u003cdd\u003e810009931430\u003c\/dd\u003e\n\u003cdt\u003eShipping weight \u0026amp; size\u003c\/dt\u003e\n\u003cdd\u003e5.00 lb, 12.4 × 12.4 × 4.8 in\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003ch3\u003eDocuments\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/6160e172f7ff6708ffce5de959d67d6c.PDF\" target=\"_blank\" rel=\"noopener\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/c55b4bc4b6c3ddd943d0de5e79e8573b.PDF\" target=\"_blank\" rel=\"noopener\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotices\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer and birth defects or other reproductive harm.
