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.

Its mine :-) I am selling it. Do you want to buy it?
Paul Lamar
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.
Paul Lamar
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
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 permission 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.
Paul Lamar
How much do you need to finish the project? $650 x 3 days for
dynotesting?
Do you have enough other parts lying around to complete the ignition?
The running engine will be worth more, and you’ll still own it.
It might be a lot easier to sell.
Or would $10K buy an aluminum version fit for an aircraft?
Dave Klingler
I think a version fit for aviation would take a lot more money than
that.
Before the Wankel is accepted as a legitimate aircraft engine there
needs to be a certified
version. In the U.S. that requires a paper trail on every part. No
automotive
engine parts are allowed. The cost of making the rotor housings
alone is enormous.
It will take a well funded corporation to do that. Mistrial tried
and failed. The European FAA has different rules.
There is no market now for low cost private aviation.
The vast U.S. middle class has lost their former disposable income.
This is a combination of factors. Robots are killing jobs. Chinese
goods
are killing manufacturing in the U.S.. Until Chinese goods are taxed
that situation will not change. The US is worlds largest market.
There is
enormous economic power in that fact. That needs to be taken
advantage of.
Paul Lamar
I just noticed that your ebay ad says, "This item is custom built
and designed specifically for experimental aircraft.” Somebody might buy
it thinking he can put it in his experimental aircraft. :)
I definitely wasn’t suggesting that $10K would be enough money to
pay for FAA certification! I was just wondering whether a little bit
more money might lighten it up and make it even possible to put it in an
experimental.
Crowdfunding sites like Kickstarter and GoFundMe usually have a
basic goal and some stretch goals. So a basic goal might be enough
money to get the engine running and dyno test it, say, $3000. A stretch
goal might be enough money to buy some aluminum end housings and ceramic
seals, say, $12000. A further stretch goal might be some step beyond
that. Maybe $50K would put the engine in an RV-4. Actually, I like that
one.
Or maybe we do it in phases. Phase I is just getting the engine
finished and dyno’d, and we do another round when that’s accomplished.
Dave Klingler
My son did the add.
I have no time to work on this.
Paul Lamar
Dave,
Besides Al end housings (RB has the front, back and narrow center. REC
in Calgary makes a two piece wide housing for the 20B) I would say TiAl
gamma housings for the DD15 turbine and gear reduction would be needed
for use in an aircraft. Paul should be able to confirm the power
recovery system weight. Not a big problem for highway trucks.
Dale Davies
Franky, thanks for the link, the Army still seems to have interest in
the rotary, for heavy fuels,

Steve Carlisle
That is a really good paper but 2011 is awhile ago.
It is kind of an overview of the R&D done to 2011.
Some of the stuff is fake news.
They are getting closer to addressing the wind in the combustion chamber.
The US Abrams Tank already has a Wankel APU.
