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.\u003c\/p\u003e\u003cp\u003eThe pulley is CNC machined from billet stainless steel, e-coated black for an OEM appearance and is press fitted 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 percent 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eIt 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 percent faster than stock. This speed was chosen after extensive engine and chassis dyno testing with various pulley sizes and supercharger speeds.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe 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\u003cul\u003e\n\u003cli\u003eFull dual pulley kit\u003c\/li\u003e\n\u003cli\u003ePress on 57.75mm supercharger drive pulley\u003c\/li\u003e\n\u003cli\u003eBolt on 187mm crank pulley\u003c\/li\u003e\n\u003cli\u003eSpins the charger 26.4 percent faster for massive torque and HP gains with tuning\u003c\/li\u003e\n\u003cli\u003eAnodized and E-coated factory black\u003c\/li\u003e\n\u003cli\u003eAppropriate belt included\u003c\/li\u003e\n\u003cli\u003eRetains factory harmonic balancer\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet\u003c\/li\u003e\n\u003cli\u003eDiameter: 57.75, 187 Millimeter\u003c\/li\u003e\n\u003cli\u003eEmission Code: 6\u003c\/li\u003e\n\u003cli\u003eMaterial: 6061 Aluminum, T304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003eProduct Type: Pulley Systems\u003c\/li\u003e\n\u003cli\u003eVersion: Dual Pulley - Press On\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APR","offers":[{"title":"Default Title","offer_id":51515917926688,"sku":"HJQF_MS100184","price":614.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9008\/1056\/files\/MS100184-HJQF.jpg?v=1777132758","url":"https:\/\/apxline.com\/products\/supercharger-drive-and-crank-pulley-with-belt-press-on-3-0-tfsi-fits-2009-2018-audi-a6-a7-a8-quattro-2013-2017-audi-q5-2011-2015-audi-q7-2010-2017-audi-s4-s5-2014-2017-audi-sq5-apr","provider":"APXLine","version":"1.0","type":"link"}
