The first time you spin out on a dirt track and the car stalls, but the battery is too weak to restart it, and other cars are bearing down on you, those 2-3 HP mean nothing...……………..LOL
I always ran an alternator on my own race cars, but have been involved with other cars that didn't.
I've been following this thread, but I really don't see how an electric fan can get the same amount of work done at potentially 30 times less energy than a mechanical fan can. It must be the new math I'm not getting...……..
The idea has been thrown out there that the car manufacturers changed over for fuel mileage reasons, but until engines were mounted transversely in a chassis, very, very few cars had electric fans. Obviously there is no way a mechanical fan can be driven by the conventional transverse mounted engine so enter the electric fans.....
