 Its mine :-) I am selling it. Do you want to buy it?

 That is a real piece of art, Paul!

 How much power did you get with the turbo compound?

 Jacobo Guimeráns

 The basic street 3 rotor sequential turbo charged is 350 HP.

 I never ran it because I did not have the $650 a day for an engine
 dyno. If the people running DARPA had any brains they would snap it
 up.

 If Mazda had any brains they would be working on a turbo compound
 rotary. 20 to 30 percent less fuel burn.

 The big problem with the Curtiss Wright turbo compound R3350 was
 exhaust valve failure. Guess what! the rotary has not exhaust
 valves.

 How were you going to use it, what application?

Thx. Julian Morrison

 strictly for testing. To prove the concept.

It would work as a boat engine however.

Paul Lamar

If you add direct injection to the turbo compound system, would the
fuel consumption be reduced even more? Or there would be no gains at all?

Jacobo Guimeráns

That will do next to nothing. Millions have already been spent on Wankel DI.
The wind storm in the moving combustion chamber needs to be dealt
with, Then you might improve it 5% to make it on a par with a piston
engine.


Turbo compound will give you 20 or 30%. Turbo jet based power plants
are already using it to improve the overall efficiency to over 50%. The
waste exhaust
from the turbo jet makes steam for the steam turbines generators.

There may already be such a power plant in your neighborhood.

Paul Lamar

Its called a bottoming or combined cycle powerplant.  I think I saw a GE
news release about a year ago claiming something like 63% efficiency;
Gas turbine/alternator + steam turbine/alternator.  With a turbo compounded
Wankel you could add SS tubing coils in and around the
exhaust system to generate steam and pick up another 15% in power and
efficiency.
