You can have 10 different ports with the same exact flow numbers, yet they can vary wildly in rpm range, acceleration and power.
However, they don’t guarantee you will make more power.įlow numbers are just one variable used for various equations to analyze port characteristics in a very complex system. Airflow numbers give insight into the potential for power. Flow numbers are important, and they do have meaning – just not the meaning most people attribute. This distinction is often lost in translation.
