How to calculate the size of carburetor needed in CFM?

The right idea would be to proportion the carburetor to the engine's volumetric potential (breathing ability). The engine's volumetric efficiency is a measurable value and with a correctly matched carburetor you will receive the best performance possible out of your engine. The formula for calculating how much CFM (cubic feet per minute) an engine requires is: CFM = Cubic Inches x RPM x Volumetric Efficiency ÷ 3456.

How to calculate CFM from RPMs?

Calculate the CFM (volumetric flow of air) at 1,200 rpm. The volume of the column of air described in Step 2 is pi (3.1416) x fan radius squared (0.5-feet squared) times the column length in feet. This would be 3.1416 x 0.25 square feet x 800 feet = 628.32 cubic feet per minute at 1200 rpm.

How many CFM do I need for 1,000 square feet?

The minimum requirement for fresh air is 100 cubic feet per minute (CFM) for every 500 to 900 square footage of the residential space. How many CFM do I need for 1000 square feet? Anything between 240 to 260 CFM is good for 1000 square feet of room.
