Hey guys

I have 8 rip pulleys and I'm currently using the belt that came with the supercharger which I'm not sure the size of it, I'm running 3-3/8" supercharger pulley with 7" underdrive pulley and I just got 2-3/8" pulley and I'm wondering what belt size I should use for the 2-3/8" ?

I tried to reach KB they are not answering and I'm leaving the country in like 3 days and I need to get the belt ASAP, if you also can provide me with manufacturer name and part number that would be great.

If I can recall i think KB use Dayco.
