All went well. Very stable with plenty of power. I'll fly another week or
so to ring out the engine and them put on the gear leg fairings and wheel
pants.
Wings level and ball centered hands off - can't ask more than that.

the nose to a 130 kt climb. Second hop all were below 460, #1 & #2

Congrats!! I think most people are removing both cylinder dams. To get my e

cond set of vents in the lower cowl to increase exit air and of course wheel
pants. They all help!

Congrats Carl.
I agree with others, 500 is too hot. I know that's Lycoming's red line but most
people think that's just too high. OTOH it will be tough to break in a new engine
and keep the CHT's below 400. But below 430 is certainly doable, and lower
on a cool day or as the engine runs a few hours (shouldn't take more than 3
or 4 to see CHT's drop). Run full rich, as fast as you can (minimize climbs),
stay low where the air is denser, reduce RPM (that doesn't help with break in
anyway).
If there's one piece of advice I'd give to new owners with new engines, it would
be: "Forget the air dams. After break in decide if you want them, and how big".

| Subject: | Overhead Air - Bulkhead Penetration |
What sized holes has everyone been punching through the bulkhead for
overhead air?
I've got the typical dual NACA setup on the sides feeding 2" tubing to the
bulkhead. I'm tempted to drill a hole in the neighborhood of 3/4 to 1" in
size and let the 2" tubing feed air through those smaller holes.
Has anyone done that and how much air are you getting? I'm not a fan of
knocking a 2" hole in a 3" bulkhead.

Congratulations on the first flight. I will have to ditto Don=99s
comments and suggest you use what ever flight technique is necessary to
keep those temps significantly lower while you work out the cooling
issues. My cylinders have never seen more than 430 on the hottest even
at ISA +30F climb conditions out West.
Good luck.
