LOM engines

Anyone with any experience with LOM engines? I am considering the benefits
of a 170 HP LOM 332CE for use in a Mustang II which is rated for a
powerplant in the
O-320 to IO-360 range. LOM sounds like it might be "real airplane" without
the other-worldly prices commanded by Lycoming, Superior Millenium etc.

Any first hand experience here?

Nope.
Just good used 2nd hand.

It is an article from the current Sport Aviation. The subject aircraft is a
LOM powered Glastar. According to the story, the owner is happy with the
installation.

Hey Unka Bob

Just curious,but what is a LOM 332 engine? I don't recall ever hearing of it.

Thanks

Thanks Unka Bob I knew you'd know. It's a Walter engine I heard of Walter
engines but I never heard the term LOM for them. Mary Carlson of Carlson
Aviation has one in their Storch replica called a Cricket. I've seen it in their
plane. See I just learned something. Just like Sister Mary Pontius Pilot used to
say "keep your eyes open and your mouth shut and ya moght learn something" :-)

Thanks

I wonder why they use such a low compression ratio? Even car engines
running regular usually run 8:1. This one is 6.3:1.
It would reduce the stress on the parts, allowing less expensive
materials than a reliable high compression engine.

My normally aspirated 150 HP Lycoming is 7.0:1
for 80 octane while the 160 HP version is 8.5;1
requiring 100LL.

I suspect the 6.3:1 is to prevent detonation
when the turbo is at max boost at 100% power.
Effective compression with turbo boost likely
exceeds 7.3:1. Higher compression could
require water injection and/or higher octane
fuel to safely remain out of detonation range.

Air cooled engines require a lower compression
ratio than liquid cooled engines to insure detonation
is never achieved under any condition. That's what
I was told, anyway.

I guess they can also use lower octane fuel as well.

6.3 to 1 is the compression ratio for the Continental A-65, which loves 80
octane avgas when it can find it.

They use such a low compression ratio so they can use Russian gasoline!
