Oh Yea of little faith. I haven't taken any new pics as we've done the
finishing working on the cowling. But, here are some from a few weeks
ago that should answer your questions. Photos attached...

OK Mark I am happy :)
BTW For the new guys. This p-port engine has been dynoed on the
Mazdatrix dyno
at over 250 HP at 7500 RPM. With a 2.85:1 gear reduction that is an
ideal
takeoff RPM with about a 70 inch prop +/- 2 inches. The rational for
so much power other than sea level performance is Mark's home base
can be
7000 feet density altitude on a hot day. Normal airplanes have trouble
taking off in the summer time. At 80% of 250 HP he will have about
200 HP.
The other advantage is high speed cruise at altitude without a turbo
charger.

Let me correct that a bit -- my density altitude is 7000 feet on a
STANDARD day. On a hot summer day, DA here is regularly ~10,000 feet.
There are many guys who cannot fly after 10am or so, and we regularly
get east or west coast pilots who land, fill up with gas, and crash a
little north of the runway when they suddenly discover they can't climb
out of ground effect & the ascending terrain gets them. I suffer the
opposite problem -- I am so used to anemic high-altitude performance
that I almost always bust through pattern altitude when I find myself
down in "fat air" at sea level.
