Why "they" use a 6+ blade fan on newer cars is irrelevant. They have slower rpm electric motors as well as air conditioning which increases air temperature greatly.
The "A" was designed with a 2 blade fan with a certain blade pitch and it was designed well. If its not broke stop fixing it.
Many guys on here like Tom,Brent and Mitch know the "A" inside out and say to use a 2 blade fan. That has to mean something.
Now we're comparing props on air planes which consume 1000-3000HP to the model A's fan. Whats next boat props?
