Looks like the results are just what one would expect from the design
information.  I noticed that that electric fan car didn't participate in 
any
of the tours at the Portland meet and that said a lot all by itself.

Unfortunately, Ron, that is the same "empirical" evidence that caused all the 
differences in "opinion" that the scientific evidence of the instrumented 
tests finally put to rest. It doesn't matter if "it worked for me once" or "it 
didn't work for me once". What matters is that the tests showed that, on a stock 
engine, the proposed design couldn't cool enough to keep up with the heat 
input - at more than about 40 mph. Not to mention hills or other heavy loads. The 
electric fan I am looking for, and I know there are several others who would 
be interested in it, would be a motor drive that would spin the stock fan (or 
a re-designed mechanical fan) at the optimum RPM for cooling. It would have to 
do that without adding too much weight - BUT - it would only have to do it 
for about 5 minutes at a time (Think an autocross run or two). I also wondered 
whether another gas motor - small, maybe something like a weed eater or chain 
saw, could power the fan at the optimum speed - or close enough. Now, that 
would attract some attention. Before beginning your runs, you walk around to the 
rear and pull-start your cooling fan drive engine. Or, better yet, have a 
starter drive sticking up through the deck lid and use a wireless impact wrench to 
start it. Cool! - Seth Emerson
