What are the calculations to size a pully if I change the horsepower of
the driving motor on an air compressor? Also will changing the
Diameter without the HP help a compressor run with less effort?

You might get a little insight into the effect of changing motor HP and
pulley diameters by looking at a Grainger catalog. Find the pages where
they advertise the air pumps. They show the effects of changing HP.
