Thank you Fred.

I can send out to you this coming week some of the most recent reports which
are available for public view.  Some of the research is not mine to pass out
as it was done as paid research for client companies.  

Dick Perry, the man who reported the 15% reduction in his IO-360 as a result
of our work is a very highly qualified builder and retired senior airline
captain.  His last project was to build a full size Jap Zero with a DC3
engine without plans.  He has his aircraft highly instrumented and keeps
notes on every temperature and operational parameter so when he says 15% it
is a reliable number.

I do recognize the "eyebrow" factor that you refer to.  It is so bad that we
never claim anywhere near the results that the customers get.  8% reduction
is all we ever state because it scares people if the results look too good.  
They only thing that has helped lately is that so many of the big companies
have been forced to adopt or consider the technology because of emissions
factors.  Several new engines in the big buck car class, IE Mercedes and BMW
have integrated it into new engines just seen at the last major auto shows.  
Federal Mogal introduced a bearing line with the antifriction coatings and
Dietroit Diesel and Cat are well along in testing.  In cars what is driving
the change is that they need to cut crevice volume between the ring and
piston top.  The ceramics allow them to move the ring up.  The solid
lubricants are well into production as a way to compensate for the fact that
the new pistons have very short skirts and tend to rock.  With the ceramics
and solid lubricants Lamborgini runs a tight sliding fit on assembly.  We
only run 2.5 thou in the aircraft.

Look for the info in the mail and call me if you have any questions after
that.  As offered before, you are more than welcome to come and be the
witness for tests.  There is generally something new on the dyno every month.
