what is a 5.0 mechanical fan CFM rating?

Sorry to bring this back from the dead.

But does anyone know?

Looking at getting a Proform fan and its supposed to do 2800 CFM.

I need something that will be just as good if not better than the stock fan, cooling wise.

My car was running 230-240* today in 75* weather.
I plan on swapping the TStat for a 170 or 160* and getting an electric fan and 130Amp alternator.
