Carb plenum, inlet .dia CFM calculation?

jackcarter1971Member

Hey Folks:

I am considering building a dual inlet carb plenum, due to height restrictions with engine cover. That said, I plan to use two 3" inlets. But I am not sure if the CFM that can be drawn through that diameter pipe (x2) is enough for my Holley 750 DP. Anyone know how to calculate CFM for a 3" pipe?
