So I would think the larger fills quicker then the small. So the power used would be comparable or negligible.? What I don't want to do is buy a v8 when a v6 is less gas mileage. I am assuming that the 5hp is my v6 and it is the same on both compressors just the compressor piece is different and runs at different rpm's.
