Carburetor CFM Calculator
If you want to determine the size of the carburetor that your engine required, then this Carburetor CFM Calculator is a tool that you can use.
A mechanical device in which fuel and air are mixed for internal combustion engines makes a suitable air-fuel ratio for combustion known as the carburetor. Moreover, the carburetor, also spelled as carburetor, is used to provide the spark-ignition engine that includes a variety of both fuel and air. Choke, liquid fuel, venturi-shaped air-flow restriction, and accelerator pump are included in the storage chamber of components of the carburetor.

Formula of Carburetor CFM Calculator
If you want to determine the size of a carburetor, you can use our calculator, or to find it manually, you can use the formula listed below:
Carburetor size = Engine size * Max rpm * Efficiency / 3456
Where,
Engine size (CID) = size of the vehicle's engine, measured in inches.
Max rpm = maximum revolutions per minute.
Engine efficiency = efficiency of an engine; however, the standard stock engine has approximately 80% efficiency.
Note:
To calculate belt length, you can use our Belt Length Calculator.
Example
For more prices understanding of the above concept, let us have an example below:
Suppose a bike has an engine of 340 cubic inches with a maximum number of revolutions per minute of 5,600, whereas the working efficiency of an engine is 80%. Find out the carburetor size using the above-given data.
Given data
Size = 340 cubic inches
Maximum number of revolutions per minute = 5,600 max rpm
Engine efficiency = 80% = 0.80
To Find
Carburetor size =?
Solution
To find the carburetor size, you can use the formula listed below:
Carburetor size = Engine size * Max rpm * Efficiency / 3456
Putting values in the formula:
Carburetor size = 340 x 5600 x 0.80 / 3456 = 440.74 CFM
