Sounds like a great idea to me. I work with MAF sensors at work for their intended purpose, measuring airflow. Some quick numbers from an engine I'm working on now:

Idle airflow - 6 g/s
Peak airflow - 660 g/s

Air is about .0806 pounds per cubic foot. Just math to get to speed...

With a 4" tube this equates to about 1 MPH at idle, and about 140 at peak flow.

Seems like an appropriate measurement range. The ones I work with output a frequency, but there are others that output a voltage. Voltage being a bit simpler to measure easily.

Just need some wind tunnel time to calibrate it.
