About this tool

Estimates the required air flow rate (CFM) for a given engine size, allowing users to determine appropriate carburetor specifications. The calculator requires inputting key performance metrics such as horsepower, intended RPM range, and displacement volume into several fields. By processing these variables through established fluid dynamics principles, it computes the necessary cubic feet per minute of airflow needed to optimize fuel delivery and ensure proper combustion across various operating conditions. Mechanics, hobbyists, and engine builders utilize this tool when sizing or upgrading an engine's intake system. It assists in selecting a carburetor that matches the specific performance demands of an existing motor, preventing insufficient flow rates which could lead to poor idling or reduced power output.
