Give it a shot. See what happens. Sounds particularly interesting with EWP. Report your results.

Hi Ed, Rusty,
Thanks fo the replies guys. However, now you have got my mate
Wally (and me!) REALLY confused. (}:<)
You are touting that 2 Evap cores as being able to cool better than
an FD rad (plastic tanks aside), but having less drag. So should I
throw away the FD core (with alloy tanks) in the race car and
replace it with 2 evap cores?
Will I then have less drag??? Will the race car then go faster, or
have better fuel economy at the same speed (a very important
factor in endurance racing)? Wow, ... talk about a "racer's edge"
..... if it's true that is ... Does anybody REALLY know ... I mean
from a practical rather than just a "running the numbers" point of
view??
Cheers,
Leon
P.S. BTW, why did Tracy need to spray his evap cores with water
to keep the enigne from turning into kettle - in level flight and at
high speed no less (in an air race or so I have read)???
e wouldn't have any more than 200 BHP would he?? If they won't
cool 200, how will they EVER cool 250?? The (lost) plot thickens,
.... almost to the point of being thixatrophic (}:>).
