overdrive belt size

So i really didn't want to start a new thread on this but ive searched and couldn't find a sure answer. Does anyone know what belt size i will need for my procharger with a 2.55 pulley and 5.7"od pulley. from my understanding the stock crank pulley is 4.7" and im currently running a 101 belt, so wouldnt that mean i need a .5" longer belt? or do they not make half sizes? the general consensus is a 102 but i really don't want to go threw trying a few different belts is someone knows for sure. thanks in advanced

I'm not exacty sure I thought i read somewhere it was 4.7, If it's 5.2 then I wouldn't think u would need a inch longerbelt for .5 bigger pulley, last I read from cfm is they hadn't tested on a procharger so they don't know the belt size they suggest take a rope and measure it

I already called CFM with the same questions and they had no idea. I am in a similar situation. On wednesday/thursday I can tell you what size belt I used for a procharger set up with the 2.67 and 5.7 OD pulley, thats when my kit will be on.
