Having a really hard time finding a belt, where do you guys get yours?
 

I have a 3.33" blower pulley and all the other pulleys are stock and i am being told that I need a 107.7" belt? Does that sound right to anyone? And if so where do you guys go to get yours? Goodyear has a 107.375 and that wont fit and dayco has a 108" and thats a lil too big

You are only talking a difference of 5/8 of an inch length and the 108 won't work with the tensioner taking up the slack?

Most parts stores have many different lengths but they are in Millimeters. Tell them you need a 6 rib pulley so many mm long and they will find one for you, the mm length is in the belt part number BTW.

108 - 107.7 = 0.3 which is just over 1/4" ... a lot less than 5/8". Did you try the 108" belt, or are you just going by the numbers?
As for the other, 107.7" ~= 2736mm.

Yeah i have a 108" belt on now and my belts slipping. And since i am only running 11lbs of boost i know its not too much for a 6 rib setup so i was thinking my belt is too big.
