Supercharging is basically a pump that forces additional air into intake to overcome low atmospheric pressure or to supply additional air that would not be there due to other limitations...
We had a champion service station compressor from the 60 ' s and it was quiet and was 175 psi but would not keep up with much as it was old and somewhat worn and designed for above stated service station use.
Polish valves improved but still sucked.
Went to a surplus supply and found what looked like a vacuum cleaner pump which is a motor with a stack of turbines to increase pressure and it had a flange on both ends so we made some adaptors for adding hoses to plumb it to the intake and add a better filter to the intake side of the pump as well as a relay on the motor lines to control the 120 volt motor.
It sounded like a quiet Lear jet when running and compensated for filter losses and put a slight boost pressure on the intake so the piston did not suck in air but allowed it to fill up with a slight pressure instead of slight vacuum at bottom dead center.
It made a great improvement in air volume and not that much increase in motor load since it was 2 stage.
It was now 3 stage...
Been thinking about using the pump on the champion just as an experiment but too many other chores.
Most any discarded shop vac could be used to do same.
Just measure your motor amps to be sure it stays in the happy place.
