2.3L Whipple + BilletFlow 4 Piece Idler kit

[SlowLNF]

I just purchased the Billetflow 4 piece Idler kit to accompany my Whipple which has now destroyed 2 Idlers. I held off on the kit because my tuner said it wouldn't be worth it but if everyone else is using it, how can't it be?

Anyways, I tried searching the section here and was unable to find exactly what size belt I will need? I have a 3'' Pulley on the blower so if anyone could let me know that would be great, thanks.

Oh, here's what's left of the most recent Idler to go.
