How much IS "way better"?  This is why I'd liked to see some serious 
comparisons in real world environments.


Hell, I still tend to consider that the cooling fan that went on Fiat 
850s looks enough like the Porsche fan to consider adapting it to the 
Corvair shroud.   Depending on year, it came in both flavors, 
aluminum and plastic.

And, it's pitched correctly for a 'Vair engine.   I might need to 
look a bit closer in the Fiat parts stash, see what's what.

Yep.  It's not really feasible to adequately cool a 'Vair engine with 
an electric fan that's gonna be running off the alternator for all 
intents and purposes, not without some help like ducted ram-air from 
outside the vehicle.

Speaking of which:   Why hasn't this come up?   If somebody really 
wanted to experiment, they could mount scoops on the fenders (ala 
Ferrari?  ;) ) and duct air to the inlet of the shroud via a 
fabricated plenum.   Combined with the alternator driven electric fan 
that so many people seem interested, it could be the difference 
between the electric fan system actually working and not working at 
highway speeds.

Besides, I always liked the looks of those trick looking NASA style 
"flush" air scoops seen on a variety of aircraft and race cars.
