Minimum Injector Flow Rate Calculator

Below is Fuel Injectors Clinic's Minimum Injector Flow Rate calculator. This calculator estimates engine airflow under the specified conditions and then utilized the caluclated airflow to better estimate the minimum injector flow rate required. Using a mass airflow (MAF) calculator for injector sizing offers significant advantages over less precise methods like horsepower estimates. Moreover, our calculator is less susceptible to different conditions such as changes in altitude, temperature, ignition timing, and compression ratio making it more reliable than static horsepower-based calculations.
