Or look at it this way. You have a 2 garden hoses. 1st one is a 1/2" hose. The 2nd hose is 1". You know the water pressure is 55 psi. Normal household psi. Which one will fill the water bucket up faster?

So,what you are saying is: that with a boost gauge plumbed in the intake plenum & both super chargers/turbo's,big or small/ set at 10psi of boost (reading on gauge)-the larger Forced induction feeders will put more air into the combustion chamber?
I say that they are very capable to;but 10psi of boost (constant) is still just 10psi of boost.
that's why there are waste gates & blow off valves/in case of over boosting with the larger air pumps.
we're feeding air through the same intake at 10psi....not a firetruck doing a pump test w/multiple size hoses.
