Does anyone know the volume of air the volumex 7 rib outputs per revolution?

So, I'm going to embarrass myself here a bit...

Per revolution a 1250cc engine will gulp 625cc (2 power strokes) and the blower outputs 1150cc. That's almost a 2:1 ratio, blower capacity to engine capacity.

Normal atmospheric pressure (at sea level) is approx 14 psi. So I should expect to see nearly 14 pounds on the gauge when the engine is running, correct? That seems like a lot. I've been told to expect 5 to 6 psi.
