Hey Tracy (and others)
Setting up for engine first run dyno (finally).
Couple of things. Is your friend who makes wiring harnesses making them
for the 20B/Lancair combo? Going to test the water and oil systems for
pressure. 30 pounds on water, and 100 pounds on oil?

66mm is not oversize so I'm surprised with no increase in power
after 2/3 throttle. Never hesitate to play with the mixture
control when testing. It is the fastest way to educate yourself on the
effects of mixture on performance, fuel burn, EGT curve, etc. You can't
hurt a normally aspirated 13B with mixture (assuming ignition timing in the
ballpark) so there's nothing to loose either.
If that top speed was in
IAS at 8500 you're not doing too bad anyway.

Tracy,

mm ford mustang throttle body, I believe suggested by you. To busy
flying to notice all the numbers. Mostly concentrating on flying and
temps. Alt 8500 ft, 40 Oat, No idea about manifold pressure.
Mixture set at mid range, but not really looked at. We have had
a lot of weather here the last few days, but is looking better toward the
end of the week. I got the diagram and printed it and realize it is a
fix, not a solution. I'll get to the airport tomorrow and draw a
diagram of my electrical system, with lengths, positioning, etc. I've never
tried running without the main buss off. I'll run it and see if there
is a differance with only the Essential buss on. Thanks for all the
thoughts, all of you.
Don
