Kevin,
It must be great being a proud new Father!!! Or Mother, depending the
analogy, physiology and psychology of the building process!
I imagine Duane Swing mentioned it but VGs in the mouth of the NACAs for the
engine certainly seems to help. It's always a little tricky getting solid
numbers but my oil temp dropped about 10 degrees (210 down to 200) after
putting on the VGs. With higher oil temps, the drop might be even greater.
As you say, with the high temps in AZ, new engine and what-all, it's
difficult to know if it is much of a concern. Does seem to be on the high
end of the usual temp range but that may all fall in place under more normal
conditions.
Good luck!
Chuck
(In the interest of full disclosure, be forewarned that I know about as much
about oil temps and engine performance as Saddam knows/knew about democracy)

After 3 years and 4 months of building, this past weekend Mike Pollock,
Velocity owner and test pilot, made the first flights of our Velocity,
N111VX. My wife and I flew chase with Milt Mersky and Dave Bertram in
Milt's & Mike's Velocity.
Elite Long-Wing, Fixed-Gear
Empty Weight 1505
Re-Man IO-360-C1E6 from Lycon (in CA) with high compression pistons
M-T Prop
Single oil cooler (in front)
Downdraft cooling
Presently in primer, no interior (just seats)
Saturday 6/28: The outside temp was about 90 (it was morning) (it's hot in
Scottsdale, AZ now). CHTs were high (over 400) on taxi. She flew
beautifully for about 15 minutes over the airport but the oil temp was
slowly rising. At 245 degrees, Mike decided to land. The lowest oil temp
on descent was 230. Mike said that the wire duct was quite hot. CHTs were
high but under 425 in flight. Oil reached around 256 and CHTs reach around
467 by the time Mike taxied back and shutdown. We were expecting high temps
until the engine was broken in but the oil temp was concerning. Duane Swing
suggested that a small NACA scoop in the fuselage at the forward end of the
pilot wire duct that holds both oil lines would help by keeping the lines
cooler in flight. We put in the NACA scoop (or hole for the time being) and
the next morning we flew again. CHTs were below 425 (mostly around 370-380)
and oil temp was below 245 the entire time. Between the engine slowing
breaking in and the small NACA for the oil lines all temps were in check.
We flew for almost 2 hours in the local practice area around 6,000'. Mike
did slow flight, stalls, steep turns and flutter tests - everything went
fine - she flew beautifully.

I should have my transition training completed sometime this week and will
hopefully personally fly her before the weekend. Can't wait and still can't
find the words...
