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.

Grayhawk
================================
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.

others are claiming that reflex is at the faired in position. That may
not be the best position. My little 320 does 215 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.
