For the 50% Spitfire, as Paul said the 20B will work. He is working on the
turbo compound from a DD15 diesel engine for better fuel economy. The air
flow through the diesel at 1350 RPM it is designed to run at is similar to
the 20B at 6000 RPM. This is calculated just by the engine displacement and
RPM. The rotary has no exhaust valves to inhibit exhaust flow. Check the
heat diagrams for the CW 3350 from their R&D on the web site. They figured
they were loosing 500HP on take off. I think the rotary will make 600HP
once Paul gets it running. Might be enough for the little Spit.

Not flight hardware yet.
The $1500 turbine has been ordered. They had to take one off the DD15 assembly
line. It is on the way hopefully. The green stuff is steel sandwich panel
with a particle board core. Extremely strong and stiff in torsion as well
as bending. Particle board is used rather than plywood as it is flat and
of consistent thickness. However it is very heavy.
We have the use of the Mazdatrix dyno.
BTW Dale, did you get the thumb drive?
