An electric air charger can claim as many cfms as they want, but like GH says, it's about volume. And to move a volume of air, and to pressurize it, takes power.
That's why superchargers are considered a parasitic loss... it takes power to turn them... as much as 15-30 hp on many engines. (turbos don't count... they reclaim lost power that is used to push air out the exhaust)...
The only electric supercharger that's actually been proven to provide a good amount of power is the Thomas Knight. And that's because it has an expensive and custom-wound triple-motor air screw that's rated at 15 hp and provides enough boost to add about 40-60 hp on a four cylinder engine. This system, however, uses so much power that it needs an auxiliary battery pack (stored in the spare-tire well) to run it, and it can only boost for up to 1 minute at a time.
If you want similar results... good luck finding a 15 hp electric motor that will actually fit in the engine bay beside your regular motor... ...note... it has to be a high speed motor, to boot.
