Of course the flow would depend on engine speed, and at some point with blades bending over it would be maxed out. Seems an electric fan wuld be nice when stuck in traffic.

I ran a Hayden severe duty clutch with a factory 7 blade fan on my '7s LeMans sport vert with a 9:1 CR 455 and stock 3 core radiator and the car would get to 210 °F idling in traffic with a 160 °F Tstat. I changed to a 7 blade Flex a lite SS fan and the car wont get above 170 °F on a 90+ °F day. I change the T stat to a 180 ° F and now it wont get above 175 °F on a 90+ day.
