A pusher fan mounts in front of the radiator.  On the one hand, it adds airflow at idle.  On the other hand, it restricts airflow by blocking the radiator at speed.

So...question.  What is the difference in airflow for a pusher fan at 1360 CFM, compared to airflow reaching the radiator (properly shrouded) at 70 mph?  Would 1360 CFM be a net gain or net loss?

I have absolutely NO clue.

Thank you, everyone.
