Not necessarily, just because a charger can flow 100 lbs/min at blah blah blah pressure ratio, doesn't mean the engine can actually ingest that flow rate.
I've always wondered what mass flow rate these engines can actually consume at each fixed rpm/temp/pressure ratio. For example: stock engine 5.9 CR 3000 rpm, 150* IAT, 4.0 pressure ratio sea level what's the mass flow? Because if you keep the density fixed (pressure&temp) and rpm fixed, the engine can only ingest a finite amount of air. To get more air in you'd have to raise density (more pressure/less temperature) or change volumetric efficiency via rpm change or porting/valve train etc.
Eric was asking just about the turbo, but you do bring up a very valid point
