Not sure, but it varies. Much more than any electric fan could do from what I've heard. You can get some power back by swapping to electric fans, a common method is two ?ford taurus/van 3.8l fans?... there are a couple write ups here somewhere

Good Morning Ya'll.
IT varies with engine speed, a locked fan 1800 RPM at 240* IIRC is 960 CFM.

960 seems low...
Very low. More like 9900 cfm or more. I used to have a book that listed mechanical fan cfm's by aplication. I remember that your average mid 70's big block car was 8000-10000 cfm and our fans are much bigger than those.

Ill bet there is an app for that....or some formula that computes # of blades, diameter of inner and outer blade area covered and angle of attack and RPM....
