For independent test results contact Rick Sargeant who did the engine tests 
for a commercial customer for high altitude communications aircraft and who 
was approved for a USAF Kinney Initiative funding for overflying the US 
Wargames using one of our engines.  SGTARK@juno.com.

Fred, the customer posted his results on the lancair list.  Dick is a high 
time very experienced airlines pilot.  Call him up and tell him he is full
of it and doesnt know how to run a test.  Let him explain why his
independant test got the results that it did.  rlperry@juno.com

If you will send me your physical address I will send you a Ferrari test
and another IO-360 customers report to compare against Dicks.

As to breakthoughs.  Yes they are a breakthrough and they are being
integrated into the engines of major manufacturers now.  The bulk of my
business is in the diesel area where we are paid to do research into engine
development and including ceramics and solid lubricants.  The problem is of
integration into mass assembly lines.  It does not readily adapt itself to
that area.  So the main work is now being done on lower volume, very large
diesels such as power plant diesels.  One such program by the worlds
manufacturer of diesels is just starting.  Dietroit Diesel and Cat are
using the coatings in tests now.  

Also if you are absolutely right then why does the new Continental Top Care 
kit pistons have the solid lubricants on the skirts.  Why did Federal Mogul 
introduce last year bearings with the solid lubricants on them and a line
of pistons for remans with the solid lubricants on them.  Must be a major
scam, right  Fred?

More independant tests.  Request NASA Lewis Research Center Tech Brief 
LEW-16512  "Tests of Thermal Barrier and Wear Coats".  Under conclusions 

#1.  "Using TBC (thermal barrier coating)----reduced the SFC by 16.1%"

#5    "The TBC coating remained intact and in good condition ---"

16.1% better SFC Fred.  Stick around, it gets better.  A customer has one
the engines with the coatings but also equipped with fuel injection and
ignition in a L360 in the shop being completed now.  I will make sure you
get a copy of the results.
