At ~7" of brace height, the C cam will IBO about 325 at it's highest DL setting.
That's with an ATA of 36" +/- 2".
The Cheetah has a much shorter power stroke, so it will lose some speed. However, a shorter ATA also means less string has to be moved.
So, you will get back some (but not all) of what you lost in power stroke, by gaining efficiency.
I would expect an adjusted IBO of around 320.
