Paul, I realize you built your turbo compound engine for static
testing, but what would it take to turn it into a semi-flying demo,
as a proof of concept for what Dale is suggesting witha  4-rotor?
After all, you could dyno it the same way you’re doing the TTC
engine, with a prop, even if it never leaves the ground.

Naw. The turbo compound system is being built and tested by the
Formula 1 teams. Each spends a couple of hundred thousands dollars
per year on R&D. Nothing like wars and competition to make rapid
advances in technology.

The first turbo compound car will appear any day. Especially if the
gasoline  prices go up again.

I would rather work on the Reno racer. Certain aviation journalist
in high places are getting very interested.

Imagine if the rotary was invented first and somebody showed up with
a Rube Goldberg piston engine :-)

Paul Lamar

You had a very different goal than the Formula 1 teams or, for that
matter, long-haul diesel engine designers who have been doing lots of
R&D on turbo compounds for decades.  Your goal was to prove that
turbo compounds were a good match for rotary engines.  It seems to me
that diesel engine designers and Formula 1 teams aren’t really doing
anything to prove Paul Lamar’s long-held assertion that a rotary
engine could be fuel-efficient.

Rumor has it the new Mazda RX9 or whatever they call it is a turbo
compound hybrid.

350 HP and 30 MPG around town.

Sometimes the Japanese engineers  work together and Honda is building
a Formula 1 hybrid turbo compound.

Now if you have a dyno and would like to test my 3 rotor TC it that
is another matter.

Where are you located?

Paul Lamar

I’m in Albuquerque.  My thought was that you’d “dyno" it using the
same technique you’ve been using for the TTC.

Dave Klingler

That is a $3,000 Motec system. There are better things to spend the
money on now. We need to make an impression on the engine market for
experimental aircraft. 1/3rd of all privation aviation in the world
and growing.

Paul Lamar

I guess I had the idea that you were planning on using a tether and a
load cell or a spring scale.  I don’t quite remember the original
post.

Dave Klingler


We were planing on measuring the weights on the tires but with
the slip stream causing lift on the wings it did not work out.
