Mike,
Andy
has the molds for my cowling and produces the parts. The cowl with the blisters
on it is for the TSIO-550 (Darryl's and my engine have larger than normal
turbos). My engine came from Performance Engines in La Verne, CA (Darryl also
had his done there last year).
Andy
also makes a cowling for the normal IO-550. Reference Lee Behel's cowl. There
are a couple of differences, that I know of, between the
TSIO-550 and the IO-550. The IO-550 cowl doesn't have the blisters and has cowl
flaps. The intake area may be smaller on the IO-550 also.
I'm
not aware of any public discussion about Andy's cowlings. As far as I know Andy
is the only source of these items (at some point in the near future Andy
will supply all the items for the Super Legacy through
Lancair).
The
TSIO-550 in my airplane does not use the standard engine mount. The mount is
specific to the Super Legacy, and again Andy has developed the source of this
item.
My
plenum has a few minor change from Darryl's. Mostly making it easier to remove
and service the engine.
I'm
not sure if that little bit of information helps much. Probably a call to Andy
at (949) 498-3875 could get you more answers.
Andy
told me a couple of days ago that some publication (I don't know which one) will
be doing an article about Andy, Darryl and the activities of their company,
Aerochia.
The
direction I am going with my airplane was settled some time ago. I wasn't
offended by your post. Like you, my only intent was to provide some information
that others might find useful.
Regards,
Lynn
