What is the formula to calculate carb size for a blower motor? I have seen it before but can not remember where.
Thanks in advance. Troy

On blower engines; one of the fewer places where bigger, is better (within reason of course). :D

{(CID X RPM)/3456} X {(boost/14.7)+1} This is a small as you what to go.
Sounds about right for a roots style with the carbs on top, which would be my guess as to what is being asked. If its a blow through arrangement its a different story.
