   Well Dave Lemon is getting a bit apprehensive. He has not been paid
   yet. This engine is easily capable of destroying itself if it is not
   properly loaded at high RPM. Mixture could go very lean at 12,000 RPM
   or higher. He is rightly concerned. Most of his dyno experience has
   been with carbs that usually provide a near usable mixture setting
   throughout the power band. Also carbs tend to have a moderate throat
   size to provide a good fuel signal at the low end. This tends to limit
   HP and RPM at the top end compared of course to say; a p-port with a
   slide
   throttle. In an airplane the load is always there. The prop runs
   into a load brick wall around 2700 RPM which of course limits the
   engine RPM to 2.85 times that or 7700 RPM.

   I am debating with myself if we should move the engine to a prop
   dyno which is more suitable for setting the mixture using Tracy's
   programming methods.

We're 3000 miles away, but if you want to discuss using our dyno, send
me a note. I've got no problem with setting up an EFI system from "scratch."

Jon

Might take you up on that Jon.
