Paul,
I like a lot of what you've done with the layout for the rotary in a KIS.
Some of the features are:

1. Easy to "baffle" the radiator to keep the pressure up to force the air
through the radiator,
2. everything up front to keep plumbing lines short,

A couple of questions though,

a. The engine exhaust is dumping right by a NACA inlet for cabin air on a
standard KIS, even assuming that you seal that off, it is going to be going
right by the canopy on the pilot's side.  I would worry that both the
possibility of a leak, and the increased noise (having the exhaust pointing
right at the door) would be a concern.

As Vance says wear ear phones! :-) (Let them eat cake?)
I think I can lower it a few inches. I don't want to get too close
to the wing however. I think the side exhaust is worth solving 
those kinds of problems.

b. Are you dumping the hot air from the radiator out the bottom of the cowl?

Jury still out on that. I will try to get as much out near the exhaust
as possible. Of course you have that suspension strut bobing up
and down... down there so some air will escape through that hole.

c. Are you using the "square tube" through the oil pan motor mount?

Yes I am. I may truncate the pan before it gets to the square tube
as the oil pickup is in the other end of the pan. KIS. There is still
plenty of room for the oil to drain back from the rear (now front)
main bearing with just a flat plate on the bottom of the engine.

d. What is the clearance between the turbo and the cowl side? What do you
recommend for heat shielding the fiberglass cowl?
Although longer path, have you looked at bringing the exhaust down and
exiting on the bottom of the cowl? -- would it fit?

Bill

Perhaps a stainless section of the cowl with louvers. I need to find
out when I mock it up how far from the cowl it will actully be.
Hopefully as soon as I recieve a few more engine parts this week
that too should happen soon.

First I need to find out exactly which turbo I will be using.
I had a meeting with Bob Keller today pres of Turbonetics and he
will make some recommendations before the week is out.

BTW in his humble opinion 35K is a piece of cake.
Also I was happy to find out the turbo is much lighter
than I thought. Bob says less than 20 pounds. I had assumed
the worst...43 pounds.
