Would running the auxiliary engine during cruise, with taller overall gearing lowering rpm, increase or decrease the main engines fuel consumption ?
pumping air for the fun of it will decrease mpg.

what size main engine and what RPM are you thinking, and I can run the numbers for you as to how much horsepower it will take.
