Monty.

I have a question for you Monty. Is it better to design a 12 inch diameter blow down
direct drive turbine  running at 6000 to 7500 RPM or use a geared down
turbocharger type turbine?

Paul,

Could you do a rendition where this was toward the rear of the engine?
Shorter exhaust route, keeps the weight closer to the firewall for CG
reasons...  On the other hand, the interference with the accessories
might not be worth the headache.

Chris Cosman

I agree with the last statement. The weight is not as heavy as one would think.
Its mostly thin sheet metal.
