Putting a higher HP motor on an impeller of a given size won’t achieve more airflow. Induction motors on dust collectors typically turn at 3400 rpm. If the impeller is bigger it will move more air but require more current (higher HP rating) to keep that RPM. A low HP motor will be paired with a small impeller since that’s what that motor can turn. If you put a higher HP motor on it it won’t turn any faster, it will just have more current carrying capacity than it needs to turn that small impeller. To get more airflow you need both a higher HP motor and a larger impeller.
