<VV> Electric Fans

[Mel Francis]

While most owners are operating well within the original design envelope, 
some are interested in cooling reliability for the higher-output performance 
applications.

On this other hand, I felt so badly for Dave Clemens last year, as he was in 
a race and threw his beautifully race-prepared engine's belt on the very 
first lap. He hustled around, back to the pits with a seriously overheating 
engine, and replaced it in record time, but it cost him the race. He's 
normally a very strong competitor and he knows exactly how to avoid throwing 
belts, but it still happens. He even empties the insides of his alternator, 
to limit the rotational masses in the belt system. Still, things go 
wrong....

So when we describe these other fan design approaches and drive systems, 
it's an attempt to help people like him,
not the regular-range drivers who are completely satisfied.
