Whipple belt size?

[SN8KBITN]

I just installed my whipple and i'm just wondering what belt size will i need to use with a 3.0 upper and 4 billetflow idlers with new bracket and the stock lower? Guys with this setup, what size are you running? Thanks

I'll get back to you in the morning, but I just did this. I think it was 77, but I'll let you know for sure in the AM.

This is not an exact match but should help.

With my 3.25 upper and 4lb lower I use an 83"

When I had 3.25 upper and 2lb lower it was 81.6"


i am estimating you around 79.5 - 80"

I just ordered 77 7/8 just to start with. I will see and go from there!

did it work? I am going with the same setup and needed to know what belt I needed. Thanks

I have the same set up and 76.5 gates works for me no slip but I use a RR non slip upper pully.
