Electric fan kit?

[Joseph Pizzimenti]

Huw,
By wiring in a relay with a switch, one can shut it
off manually at speeds of over 40mph where airflow is
enough to not require the belt-driven fan, thus
returning some, if any, power.
Admittedly, there MAY be some power loss at low
speeds, but if the current is not drawing at higher
speeds and at the track, especially, this could be a
good thing...at least in my limited grasp.

Educate me,
Joe
