Hi Scott,
I have meticulously calibrated my EFIS so that temps and
airspeeds are correct on my GRT EFIS. I think we need to race.

I
believe your Chin tire had gone flat whilst taxiing to the start line.
It was very hot and humid that day.................
As
far as Redmond, consider this posting I made in Sept 2006:

I would like to know if a 320 lancair with a
Pen yan engine that has pistons, fuel injection, electronic ignition
and all
would perform much different than a 180hp 360.
Ron,
Yes, it would perform differently. In some cases, the
320 in cruise and at the lower altitudes can do quite well against a
360. But in climb and higher altitude performance, there is no
replacement for displacement. However, each specific set up can yield
vastly different results.
What does Penn Yan do that's so special? What
compression ratio do the pistons provide? Whose electronic ignition?
How heavy is the airplane? How much fuel does it carry?
I believe I am flying with about a 170 HP 320 (some think I
have more), 9:1 CR, std fuel injection with an atomization assist, dual
Light Speed EI, a Hartzell CS prop and a variety of minor airspeed
enhancements. At low altitude I am only 4-5 MPH slower (Air Venture 500
mile cross country race) than my friend's "blueprinted" IO 360,
10:1 CR, MT CS prop, P-Mags, etc. I use less fuel. BUT, he really wipes me
out in climb rate and speed at higher altitudes.
At this year's Lancair 100, I beat all 4 of the other 320
equipped aircraft and 6 of the 7 360s that ran the race.
On the flight leg from Casper WY to Redmond OR, I did not
want to land for fuel so I flew at 12,500 MSL (13600 d-alt) running 20-30F
LOP. Over Boise ID: 152 KIAS, 186 KTAS, 189 Kts ground speed at 6.3
gph and 29 degrees BTDC timing. That was at 19.8" MAP and
2500 RPM.
Maybe someone else can provide comparative data for a 320 or
360 as I might not be the best to compare against.

The tower time keepers claimed I did 210.7 Knots. I
don't know what they were smoking.

Craig,
My airplane cruised at 215 kts until I discovered that the static line was
disconnected in the cockpit. Now that it is reconnected, my 7,500 ft max speed
is 195 kts.
Oh and by the way, in the last Sun & Fun 100, in 1992, I Believe, Bill
Harrelson came in first and I came in second. I navigated incorrectly and flew
an extra 5 miles. Bill beat me by about 20 seconds. I like to say that I have
the fastest 160 hp Lancair. In the 1993 Redmond race I came in first. Scott
Krueger's IO-320 is 5 to 10 kts faster than mine because he has more that 160
hp.
You are either running at over 200 hp or your airspeed indicator needs to be
corrected. No 160 hp Lancair can fly faster than 200 kts at altitude.

kts at sea level. 210 is about the average cruise at 7500. I am
dialing in an extra 1/2 inch (measured at the trailing edge of the flap) of
reflex. While flying in formation I have determined that for my airplane
this is the sweet spot. Too much will slow it down and any less will
too. The difference between the faired in position and my reflex position
is 7-10 kts. I also have the gaps on the flaps taped and gap seals
on the ailerons.
