Paul,

Have to chuckle at some of the dumb-assed things that
get printed in Sport Av.  I, too, laughed at the 60K altitude
planned for the new Exxon tiger RV-thingie.  There are a lot
of good papers in the NACA files on the *serious* problems
that come up trying to cool an engine (esp aircooled) at very
high altitude.  A quick calculation of the density times flow
rate shows that there isn't enough mass to carry away the
heat.  Some of these people need to read a bit of tech
history occasionally - there were a lot of smart folks working
on these problems with *big* military/industrial budgets
and there research is well documented.  No need to
reinvent the wheel.

PS I,too, missed you at the tower Friday (I was late) and
Sat.   Friday was miserably hot, Sat was very nice.

PPS Not to mention the extreme induced drag at 60K with
a short stubby wing.  Wonder why they think the U2
wing was made so funny?  Styling?  I'd actually be impressed
if he can break my friend Jim Price's record of 35K+ in a
nearly stock Long EZ with that machine of his.

Bill, do you have any info on sizing turbo's and intercoolers 
for 230 HP at sea level and obtaining boost as a function 
of altitude at standard temp lapse?
Assume a 2.6 liter engine. I have the Macinnes book.
