Hi Robert,

Your statements are true... but are not accurately presented.

Alcohol will only run cooler if/when the timing and carburetion are
adjusted to run on alcohol. If you take a gasoline engine and fill it
with alcohol without adjusting the air/fuel mix and/or timing then you
will run hotter and get reduced gas milage.

In addition: The same water-cooled engines that can run without a fan
on alcohol could just as easily run without a fan on gasoline under the
same conditions. This was a common trick to get a quick HP increase on
1960's cars that were run on the highway or dragstrip. At highway speed
the fan isn't helping to cool your vehicle so why waste the HP required
to turn it?

I'm not against alcohol as a fuel, I just don't like seeing critical
details left out.

Happy trails,
