Marv:

I would like everyone who reads the LML to know that Lancair does not
have a negative position to take with either Rick Schrameck personally
or his company(ies).  The fact that he sells a supercharger that some of
our customers may wish to use is of no concern to us other than we wish
the customer to know that it may void their warranty with Continental.

I did see the photograph sent by Ron Jones of Rick's panel that shows a
manifold pressure of 27.2, cylinder head temperatures of 379 degrees and
EGT's of 1363.  I would be interested in knowing what his readings would
be at higher power settings and leaner EGT's.  I do know that with my
own turbocharged Continental engine in my IV-P, I experience cylinder
head temperatures of no greater than 356 degrees at 30" of manifold
pressure, 2500 rpm's and Turbine Inlet Temperature's of 1650 degrees at
FL250 and above.

Without mentioning names, we did have a customer using Mr. Schrameck's
supercharger who was experiencing high cylinder head temperatures.  We
were able to assist that customer in reducing, somewhat, those
temperatures by providing additional baffling material.

Whether you turbocharge or supercharge, you more likely than not will
experience an increase in induction air temperature.  This increase in
induction air temperature may translate to higher cylinder head
temperatures.  To eliminate any additional cylinder head temperatures
experienced with turbo/super charging, you may wish to check your engine
baffling as well as add intercoolers.

Anyway, Lancair has no official position relative to the Schrameck
supercharger and should Continental ever endorse its use, Lancair will
be glad to include it in its fast build engine program.
