Carburetor Calculator

Our Carburetor calculator helps you determine your maximum carburetor size in CFM for the street by entering your engine displacement and maximum RPM.

Calculate Your Carburetor CFM Size with Ease!

Enter your engine’s displacement in cubic inches and its maximum RPM to determine what CFM carburetor you need.

How Our Carburetor Calculator Works

The carburetor CFM (cubic feet per minute) calculator is a tool automotive enthusiasts, mechanics, and engineers use to determine the required carburetor size for an engine. A carburetor is a device that mixes air and fuel in the correct ratio and delivers it to the engine’s combustion chamber.

The calculator works by taking the engine displacement (in cubic inches) and the maximum rpm of the engine as input and then using a formula to calculate the carburetor’s required CFM.

Why Use a Carburetor Calculator?

There are several reasons why someone might use this calculator. First, it can help ensure that the carburetor is properly sized for the engine, which can improve performance and fuel efficiency.

Second, it can help identify potential problems with the carburetor, such as if it is too small and causing the engine to run lean or too large, causing the engine to run rich.

Finally, it can be used as a diagnostic tool to help identify problems with the engine, such as if it is not producing the expected power at a given RPM.
