I am an engineer but have a rather dumb question regarding superchargers for engines and probably compressors in general.
Most specifications are give as XXcfm at XX psi. I am trying to understand if this truly means we are moving that amount of air at the rated psi or if that means that volume of air at ambient pressure, compressed to XXpsi??
I guess my misunderstanding regarding SCs for engines is the actual volume of gas going through the engine does not change assuming all engine parameters stay the same. The only thing that changes is the pressure or density of the gas. So by cranking up a compressor, we really not not going to be using more CFM, we will be using the same CFM at a higher pressure. Am I off track with this? It is late so...
