Gates belt

[ManNmachine]

I searched on Cobrabob and local parts store. Before I make my own decision on size, if anyone is running this combo or know what size will work best, let me know. Thanks in advance.

3.25 whipple
90mm idlers
motoblue aux idler
3.2 alt pulley
stock lower

If it helps I had a whipple 2.3 with a 3" upper stock alt pulley, stock lower pulley and a motoblue 90mm idler I had a gatorback 75.5 in. I found some belt dust on the crossover so I installed a 4 piece billet flow set and a 76" gates. I would get a 75.5 and a 76 then return the one you dont need, the stop is also ground off my tensioner so I have a little more adjustment.

I used the gates 080790 and it's working good so far, been about two weeks now and I haven't seen any signs of slipping.
