How do you calculate blower drives?

If you Know: eng size / blower size, can
you calculate drive ratio to give a certain boost?

here's a partial, possible method (maybe spark some comment). thanks to Moog
Use the specs of the blower to see what flow it gives, eg my 40ci---195 cfm at 6000 rpm
..... 450 cfm at 12000 rpm.(measured at 6lbs)
Then match to engine flow rates (this is where things get weired-- cause I cant
calculate this yet.)
I am pretty sure that trial & error will be needed in the end. So many factors will influence Boost. If I can get close it will save me time and money on set up.
