Turbo PSI vs. Boost

Ok , everyone talks about airflow and max psi for psd (40-45psi before gaskets blow) but psi is pound per sq. in. wouldn't you want to measure max flow in cfm cubic ft. per min.

for ie. if you force 1200 cfm through a 3" pipe you have a psi fo let say 35 pounds. if you pass that same volume of (1200cfm) air though a 4" pipe you should have a psi of some thing like 20 pounds.

my point is that you can't compare psi from one turbo to the next _ htt to gtp38r, to he2. to make a proper selection of turbo for my aplication i need to know cfm right?
