Brammo Atom2 stock 245hp supercharger belt size.

[maverick1]

I was hoping someone could let me know the part number for the supercharger belt for a stock Brammo Atom2 245?
Probably going to do one more cross country trip, and though having a spare belt with me might be a wise move.

From the manual:

Engine Serpentine Belt
GM Base & Stage 1
NAPA/Gates
25-060512
(20mm x 1315mm)

Engine Serpentine Belt
GM Stages 2 & 3
NAPA/Gates
25-060505
(20mm x 1295mm)

I just looked at my Atom, and the spare belt I carry is a NAPA Micro-V 25-060505. The description lists it as 21mm x 1295mm, not 20mm. That's on the "fixed" Brammo 300.

According to the manual, these are the Base and Stage ratings on the 2.0L LSJ:

Base    - 205HP
Stage 1 - 230HP
Stage 2 - 245HP
Stage 3 - 300HP

So, it looks like the 245 and 300 use the same belt.
