i need the belt size # for a 3.33 pulley on a V-1 charger.

 

You can use the same belt that you were using with your stock pulley. You will not need to get a smaller belt unless you go with a 3.25 or smaller pulley. If you still don't know the size of the belt then just go to AutoZone and ask for a 6 ribbed 69.5" belt. That will work fine for 3.48" as well as 3.33".
