13B Airflow rate

How do you calculate the airflow rate (in cfm) for a rotary engine? I know how to do it for a piston engine, but...

The end result of all this is I am trying to figure out how to size a turbo/supercharger for our engine. Also, does anyone know the Volumetric efficiency for a 13B of the top of their head? Thanks much.

Double the piston calculation because there is a combustion event every rovolution as to everyother for pist-on.
