This Carburetor Size Calculator helps you determine the ideal carburetor size for your engine based on three key parameters: engine displacement (CID), maximum RPM, and volumetric efficiency. By using these values, the calculator computes the airflow requirement in cubic feet per minute (CFM), ensuring your engine receives the right amount of air for optimal performance.
Understanding the correct carburetor size is crucial for enhancing your engine’s efficiency and power output. A carburetor that is too small can restrict airflow, reducing performance, while one that is too large can cause poor throttle response and reduced fuel economy. Use this calculator to find the perfect balance for your engine.
