Throttle Body CFM
 
Single dry TB, 2.204 diameter hole with a throttle shaft going through..Going to guess .250 dia. ,on a V6 engine.

Any way to compute or figure the CFM? I'll take an educated guess at this point.
Thanks in advance

This might be of help.

Mark, my rough calculations shows around 440 CFM @ 28".
