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.\u003c\/p\u003e\n\u003cp\u003eAPR'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.\u003c\/p\u003e\n\u003cp\u003eUpgrading 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.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eSoftware sold separately\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKit Includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"bullet\"\u003e\n\u003cli\u003eAPR 3.0T bolt-on supercharger pulley\u003c\/li\u003e\n\u003cli\u003eAPR 3.0T bolt-on crank pulley\u003c\/li\u003e\n\u003cli\u003eMatching belt\u003c\/li\u003e\n\u003cli\u003eCrank and supercharger pulley hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAPR Stage 2 Calibration Results:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cpre class=\"bbcode_code\"\u003eAudi S4 \/ S5 (B8)\n\n\u003cstrong\u003eStage Fuel Grade Power Torque Gain Over Stock\u003c\/strong\u003e\nStage 2 Dual Pulley        91 AKI \/  95 RON  445 HP  412 FTLBS  +100 HP   +80 FTLBS\nStage 2 Dual Pulley        93 AKI \/  98 RON  465 HP  428 FTLBS  +120 HP   +97 FTLBS\nStage 2 Dual Pulley       100 AKI \/ 104 RON  513 HP  459 FTLBS  +168 HP  +126 FTLBS\nStage 2 Dual Pulley       104 AKI \/ 108 RON  527 HP  469 FTLBS  +182 HP  +136 FTLBS\n\nAudi S4 \/ S5 (B8.5)\n\n\u003cstrong\u003eStage Fuel Grade Power Torque Gain Over Stock\u003c\/strong\u003e\nStage 2 Dual Pulley        91 AKI \/  95 RON  445 HP  415 FTLBS  +134 HP   +98 FTLBS\nStage 2 Dual Pulley        93 AKI \/  98 RON  468 HP  432 FTLBS  +157 HP  +115 FTLBS\nStage 2 Dual Pulley       100 AKI \/ 104 RON  513 HP  461 FTLBS  +202 HP  +147 FTLBS\nStage 2 Dual Pulley       104 AKI \/ 108 RON  527 HP  471 FTLBS  +215 HP  +157 FTLBS\u003c\/pre\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003ePlease note that stage 2 software is required for use with this kit.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e","brand":"APR","offers":[{"title":"Default Title","offer_id":52727773593894,"sku":"MS100185","price":491.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/2131\/5878\/products\/apr-3-0-t-bolt-on-dual-pulley-kit-ms100185_1.jpg?v=1682143778","url":"https:\/\/store.ngpracing.com\/products\/apr-3-0t-supercharger-dual-pulley-and-belt-kit-bolt-on-open-box","provider":"New German Performance","version":"1.0","type":"link"}
