carb cfm ratings

I pretty sure the last formula can do that.

Basically the formula worked out if I did it right to go 2bbl to 4bbl divide by 1.41 and the other way around divide by .71

I got that your 230 cfm 2bbl if rated like a 4 bbl would 163 cfm close to my 180 guess and a 650 would be 915 cfm.


Can I ask why you need to know ?
Is it to see if a 650 is to big for /6 or something?
