Maybe the enclosed scale drawing of my engine and airframe will help some of
you guys to decide on starter location.  The rad shown (19" long x 2" thick)
is just shown for illustration.  When I try to stuff the sample radiator up
into where the starter is, it looks pretty ugly to me. If you don't have a
CAD program, print this out,  make a paper doll cutout of the radiator and
play with the position.  I can envision a fairly clean inlet and diffuser on
the lower cowl that would work pretty good.  This might even be a usable
spot for a NACA scoop.

To my way of looking at it, the space occupied by the starter is not very
useful for anything else.  Even a duct at that location isn't very
promising.  The RV-4 engine bay shown here is taller than some and shorter
than others.  Total vertical height at the firewall is 31 inches.  I know
this is substantially more than the Glasair (I'm working with a Glasair
flyer on his rotary installation) and pretty sure the Lancair is just as
short.

One more time, If you haven't done a drawing like this for your airplane,
it's way too soon to decide starter location.

After you've done this and decided on a different location, I'll be glad to
furnish a CAD drawing of the adapter plate & hole pattern.

I'll upload some pictures & words on the illfated exhaust system soon.

Glad to see you made it home safe and sound Tracy.
This is fine for a two dimension side view. Can't beat a mock up for three dimensions
however and my mock up foam rad (19 X 2 by 24 ) fits fine in the stock KIS Cruiser 
cowl where the starter goes. If you do make drawings use lateral plane section 
drawing every three inches along the airplane center line starting at the prop flange
back to the firewall similar to this rotary reno racer drawing.
