Increasing the pulley diameter by five percent means the alternator turns slightly more slowly for a given engine speed. This can reduce sustained high speed loading on the alternator during enthusiastic driving while retaining useful charging performance in a sensibly configured vehicle.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe pulley is CNC machined from 6082 grade aluminium billet, with close control of the diameter, belt grooves and mounting interface. Accurate machining supports correct belt tracking and smooth rotation, while the low mass billet form avoids adding unnecessary inertia to the accessory drive. The oversize design must be considered alongside the rest of the belt system, particularly where reduced supercharger pulleys or non-standard crank pulleys are fitted.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eBecause the pulley alters alternator speed, charging voltage should be checked at idle and under electrical load after installation. The anodised finish provides corrosion resistance and allows the pulley to become part of a coordinated G54 engine bay package. It is an engineering led option for owners who want a measured change rather than a cosmetic modification alone.\u003c\/p\u003e\n\u003cp class=\"p3\"\u003e\u003cb\u003eDesign features and customer benefits\u003c\/b\u003e\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li4\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eFive percent larger diameter reduces alternator speed slightly.\u003c\/li\u003e\n\u003cli class=\"li4\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eIntended for suitable modified and high engine speed applications.\u003c\/li\u003e\n\u003cli class=\"li4\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e6082 billet aluminium, precision CNC machined.\u003c\/li\u003e\n\u003cli class=\"li4\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eAccurate groove geometry supports belt alignment.\u003c\/li\u003e\n\u003cli class=\"li4\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eLow mass design limits added accessory drive inertia.\u003c\/li\u003e\n\u003cli class=\"li5\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003eAnodised in a range of colours.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"G54","offers":[{"title":"Red","offer_id":57056874496324,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Gold","offer_id":57056874529092,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Black","offer_id":57056874561860,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Blue","offer_id":57056874594628,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Purple","offer_id":57056874627396,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Green","offer_id":57056874660164,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Cyan","offer_id":57056874692932,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Titanium","offer_id":57056874725700,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"Anthracite","offer_id":57056874758468,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/apexkollectiv.com\/products\/billet-aluminium-alternator-pulley-5-larger-i-r52-r53-cooper-s-jcw-gp","provider":"Apex Kollectiv","version":"1.0","type":"link"}
