[QUOTE="tjsparky, post: 16312898, member: 59379"] Could you tell me what belt to run with a 13 GT500 tvs 2.3l supercharger. It will have a 2.4" upper pulley and a 90mm idler from VMP. It appears we still use the stock belt on the install of these 2 items. According to Gates the RPM belt that replaces stock is... K100837RPM, [URL]https://www.gates.com/us/en/ymm/search/vehicle/result?equipment-clazz=Passenger+Cars+%26+Light+Trucks&vehicle-type=Passenger+Cars&year=2013&make=Ford&model=Mustang&engine=V-8+5.8+L[/URL] and here... [URL]https://assets.gates.com/content/dam/gates/home/resources/resource-library/application-specs/428-3291-rpm-belt-dimension-list-newbrand.pdf[/URL] Depending on what you look at it is different numbers in size outside circumference 84.25” or effective length of 83.66” for the stock gates belt of K100837RPM. I see that a lot of people go with the gates K100840RPM belt with these same mods and its numbers are outside circumference 84.06” or effective length of 84.625” So I'm a little confused on which to use. Thanks [/QUOTE]
