Good evening, Paul!
My name is Jacobo and I'm from Spain. I'd like to subscribe to your
newsletter because I'm very passionate about the Wankel engine. But in
my case, I'm more interested in the automotive uses of the rotary
engine. I believe that there are some innovations in aircraft Wankel
engines that can be successfully applied to automotive Wankel engines.
I'm looking forward to your newsletter. Best regards from the other side
of the pond!

Well if you want to build a really high performance car the Mazda Wankel
is for you.
If you can find an RX2 made in 1972 or later or 1974 RX3 and later.
All late Mazda engines will bolt right in including the RX8 engine .
The 1973 RX2 weighed only 2000 pounds.
With our all aluminum 200 pound Mazda TTC turbo 650 HP will give a
spectacularly performance
both in acceleration and top speed. The rear axle will not be needed to
be beefed up
as the torque required is more related to the width of the rear tires.
The tires will just
spin if you apply too much HP. A high mounted rear wing will, with some
work on the
nose down force, also result in an increase in cornering G's.
Check out
http://www.rotaryeng.net/who.html There is a lot of car info
on that section
of the web site. I can help you with any changes you might want to make
on the car.
Here is a 800 HP drag racing turbo engine.

What I have in mind is building a four rotor engine suitable for both
street and endurance racing. I was originally considering going with a
naturally aspirated engine so as to not increase fuel consumption way
too much. But I've been reading about turbo-compound engines on your
website and I think it ought to be the best way to go.
I'd like to ask some questions before going ahead with the planning (and
to clarify doubts I might have). I hope you can answer them:
1. How much power can be recovered and brought back to the engine by a
turbo-compound system in terms of percentage? How much would fuel
consumption and range improve?
2. I read that you were building a turbo-compound system for rotary
engines. Did you manage to finish it and test it? If so, were the
results satisfactory?
3. How much boost can a rotary engine resist safely without breaking apart?
4. Would the use of a turbo-compound system increase heat and mechanical
stress on a wankel engine? If so, how can the engine be protected
against this heat and mechanical stress?
Looking forward to hearing from you, Paul. Best regards.

A turbo compound version is 20 to 30 percent more power with the same
fuel burn.
I finished it but I did not run it on the dyno. I gave a talk to the F1
engineers and
they adopted a hybrid version for F1. You can read my talk at
http://www.rotaryeng.net/Oxford-Race-Tech-art-Dec-08.pdf
There are now four companies building turbo compound engines. Mercedes,
Ferrari
Renault and Honda.
Well we have had it up to 85 inches of Hg and it is still running fine.
I don't know what the max is. I'll bet it might be over 100 inches of Hg.
Turbo compound would not increase heat unless it was a hybrid version.
I don't recommend that as it increases weight and cost. It does nothing
for an airplane.
