Hi! I found this on eBay and thought you might like it! Check it
    out now! Turbo Compound Mazda 3 rotor gasoline engine with turbine
    and turbine gear box. http://r.ebay.com/HLVEas Thanks, regards,

    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 no 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.

    All this time you’ve been carrying that torch, and all that work,
and you won’t finish it!

    A few years ago you said you needed to finish your ignition system
first.  Why not do the last bit of work and get it running?

    If the engine were running, I have trouble believing that someone
wouldn’t step up and volunteer to dyno it.

    Dave Klingler


    The patent on the ignition system is still pending.

    I am 81 I need to retire. I am selling a lot of things to come up
with enough money
    to take care of me when I can't remember my name :-)  Unless your
near my age
    you will not understand :-)

    Paul Lamar


    I understand perhaps more than you might imagine. :)

    But a demonstration of this engine running would be a hell of a
legacy, and it’s more apt to lead to retirement money than just selling
the parts on ebay.  Why not do a gofundme or some other crowdfunding?
You’ve raised a lot of awareness for this thing.  I’d be very surprised
if you can’t raise $10K to finish the project.

    Dave Klingler

    You have my permision to set that up. When you have collected
$10,000 I will go ahead
    with the project unless I sell it first. Then we will return the
money to the donors.

Back to the powerplant ,is the compounder unit a salvaged
unit from something else? Or custom made?


Richie Barrow

Brand new part from the DD15 truck dealer.

Paul Lamar


If we wanted to replicate your build, what turbocharger or centrifugal supercharger would you recommend?

Jacobo Guimeráns

The stock Mazda  3 rotor comes with two sequential turbo chargers.
Then you go to a truck company that sells DD15's and buy the blow down
turbine and gear box.

Then you spend a week or two tig welding the exhaust and intake pluming.
Then you modify and construct the mechanical connection if you have a machine shop.
That will take another week or so if you know what you are doing.
