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,

and here...

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
