Does anyone have the formula or method to calculate the total CFM air
 flow for rotary engines?I need to figure it out to make the appropriate selection for a blower.
I plan on cnc my own roots blower, seems to fit my needs for the rotary.

The tuning has a large effect and the type of intake ports.
Tuned p-ports can give you 120% VE.
