Peter, no such things as compressors or superchargers, they are called pumps.

If you like to send me your home email I'll copy the range charts for you and you can play around deducing what information you wish. 29 charts in all.

Edited to add a few data points.

I've assumed a gross weight of 115,000 pounds and an ISA isothermal atmosphere of -56.5°C. These are for best range.
