Supercharger Belt Sizes

Ugh i needed the 1075 and they send me the 108! Wouldnt be a big deal except my dynotune was scheduled for tomorrow morning. I called around town but nobody had the 1075 available, i think that extra 1/2" would probably cause belt slip so probably not good to get the tune until i have the 107.5". Opinions?

Does anyone know if the idler pulley diameter also effects the belt lengths?

Paxton/Vortech used oem 90mm idlers and a 90(3.5") idler on the bracket. But I have all 76mm idlers from an diy 8-rib conversion.

Wanted to know if the original belt that comes with the kit will work?

You may need a lightly shorter belt. And you might not depending on how much adjust-ability you have and your tensioner.
