Hi Paul-

Well, I'm almost afraid to say it, but the construction on the Mustang 2
seems to be... finished...  Terry and I were out at the hangar to work
on it today & around 2pm we ran out of things to work on -- the 'to-do'
list was empty.  There are of course some areas of polish that we could
work on, but nothing that impacts flight readiness.

Our EC2 is back with Tracy right now getting the latest firmware to help
with the PPort tuning.  He also confirmed that we'll need to turn down
the injectors since we have larger than the stock.  Once the EC2 comes
back, we're going to spend 'quality' time getting the tuning done & then
I guess we'll start taxiing it around.

Geez I hate saying that it's done.  I've been avoiding the "when will it
be done" question for so long now, it seems a bit strange to think that
there is nothing that must be done before flight...

Oh well, the FAA inspection can still kybosh everything I suppose.

I need input. Got any new pictures. Especially of the ram air box as
I am worried about fuel vapor spit back from the tuned intakes. It
would be too dangerous to fly or taxi it without it. What'ch got?

Here are some old pictures for the new guys.

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.
