It's intriguing to see the input regarding this thread.  I'm curious about
the marked differences in experience from those in the Fred Moreno camp to
those in the Dennis Johnson camp.  It would certainly be useful to know the
statistics.  For instance, how many have what they consider good engines
from Performance Engines and how many do not?  How many have had early
overhauls and at how many hours and so on?  How many engines has Barrett
Performance Aircraft overhauled (and/or others) at what hours and how many
of those were deemed OK (didn't really need the overhaul or IRAN)? Could
manufacture date be a significant factor in the differences?  Were there
changes at Performance Engines at some point that brought about the
problems?  Have those been corrected and are the current engines being built
any better?  

One issue is that their (Performance Engine's) reticence to talk with
customers once the money is paid hurts their credibility.  I have firsthand
experience with this problem and I gave up trying to contact them two or
three years ago once Stuart Featherstone left the company.

Clearly from the aluminum my engine has been making, tear down is the only
choice, but I don't have a clue yet, what is causing the aluminum wear or if
Performance Engines did anything suspect to bring this about.  I do know
that I had the same VERY old rocker arms of same vintage that Fred had in
his.  I removed and had them magna fluxed: they all passed.  Will know more
later.

Good luck with those Karma gods, Dennis.

As another data point, I have 550 hours on my Performance Engines IO-550
without problems and I know others with similar experience.  Mine was not a
racing engine.

Of course, posting this message will certainly induce the karma gods to make
my engine fail on my flight tomorrow!

Legacy, 550 hours
