I'm Awesome
Forgot to post this one. That is a GMT400 pusher fan with the shorter bracket flipped upside down and the longer mount legs bent to hold the fan in the desired location. They work fairly well.

Hiya, me again.You earlier cited the cop cars as an example:
“It's not impossible; the cop cars idle for days without a ‘China Syndrome’!!”
yet you don’t like their method:
Ok then, show us the cooling fan solution(s) you craft that finally satisfy your objective. I’m interested.
On the topic of blower motors:
Measuring the voltage and current is easy-peasy, multiply them and their product is the applied power; it doesn’t tell the tale?
“Tach it” - do you need the RPM? Can do, with a ‘scope.
Yes, I have thought of adding a pusher fan to my direct drive setup. Who makes the one shown? Was it effective?
No. Nobody involved with performance work likes today's factory high temps, and one of the first mods you see is to get those temps down. I fully agree with this as an engine builder and enthusiast.
Yes, motor rpms. Motors have a "KV" rating, which simplistically, is how many rpms per volt they turn. The higher the KV, the faster they will turn at a given voltage, but will draw more amps. As to a measure of "work", then amps times volts equals watts, a measure of force or work.
So again, if we work out the rpms of our current fan motors, we could then search for a higher KV motor. Of course, it would then be on us to determine if our relays, resistor packs, and wiring are up to the task of supplying the higher amp draw. There's no free lunch; not with motors, engines, nor women...
