REFLECTOR: center spar strength, dynafocal engine mount, a promising engine

[Andy Millin]

Doug,

I had two buddies come over to help get the engine mount on.  It took all
three of us and a 2x4 as a lever.  One held the engine.  One used the 2x4 to
pry the mount open and the third slid the bolt in.  I don't know if it is
the same for the IO-360.  I know I don't want to have to take the thing off
again.  :)

Can I drill holes through the back of the spar to run the fuel line and
alternator cable through the firewall? Isn't the strength of the spar in the
caps?

Also, is there a trick to lining up the holes in the type 1 dynafocal mount?
I can only get one 7/16" bolt to fit. I've got 3/8" bolts in the other three
holes.

This ECI IOX-360 engine looks promising.  ECI rates it at 188 hp with 8.5:1
compression even though it's a parallel valve. I think they get the other 8
hp from cold air induction, improved air flow, and the fuel injection. The
Lightspeed literature says that dual Plasma III electronic ignition adds
another 6%, which kicks it up to 199 hp. So almost 200 hp for less weight
and size than the Lycoming angle valve IO-360. On the test stand, it starts
easily and runs smoothly. Can't wait to see what it does in the air!
