Walter,
Thanks for the feedback.
"Aircraft Turbo charged engines will not detonate if they are conforming
engines and are run on conforming fuel unless the pilot pulls a stupid pilot
trick with the mixture! <g> "
Spark plug erosion and top of piston erosion show
definite signs of detonation but additionally I look at the bearing area of the
connecting rod and the back side of the rod bearing for black carbon
streaks. This also indicates that detonation has taken place. This
may come in handy when looking at a customer's engine that you have not
had 1st hand exposure to. cb
"It's interesting to note that the Lancairs, and the IV-Ps in particular,
tend to run hot. The baffling isn't as good as it could be. Running a CHT 50
degrees cooler buys you about 5 octane points of detonation margin. THAT is not
an insignificant thing."
Actually....in my opinion, that is a huge
thing. When you have time, please send a personal e-mail relative to
your Advanced Pilot Seminars. I've followed the ADA
cooling exchange with great interest. cb
