Here are some pictures of Tom Parke's Mazda turbo three rotor engine
 in a Lancair ES. The engine compartment of this airplane is about the

same

 size as a Cessna 206. The Mazda turbo three rotor fits with room to

spare.

Paul,
It is not clear to me how Tom Parke's cooling will work. I looked at the
recent pictures and some earlier ones, and the air has to flow over the
engine, and then pass through the radiator at the back of the engine
compartment.  This means the engine compartment has to be a pressure

plenum.

On the engine's right side I see a baffle to seal the air flow, but on

the

left side, it looks like the air can flow out alongside the exhaust

piping

and bypass the radiator.

What am I missing?  It is such a neatly done assembly in all respects of
workmanship that I feel that I must be missing something.

I don't agree with the way he is doing it. Here is another picture.
I think he will have the same problems as Power Sport has.
the radiant heat from the turbo and exhaust will add to the temp of
the rad cooling air.

He has a lot of room on the right side of the engine for
a Engineair type oblique rad set up which has proven to work well.

Is that a Ross PSRU on the 20B?  Wonder how well it will handle the
increased HP.

These are quite old pictures and I have not heard from him lately.
Much of the really bad stuff we have heard about the Ross came in after
I received these pictures. He may have changed his mind since then.
