4-cylinder engines are either small or have balance shafts.  They are no
longer rough. MX-5 has minimal RX8 parts.  Manufacturing tools and
transmissions, yes, parts no.  If everybody wants a rotary, how come
they're not buying the rX8?
I purchased my RX7 in 1979.  It has sat only 25 years, not 30.  ds

You think I don't drive 4 cylinder rental econ boxes every
few months? Some times I thrash them all over Europe. I don't
know what happened to you Donald. Your the guy that went 238 MPH
in an RX7 at Bonneville. What happened to your spirit?
You are getting really boring :)

BTW  Mazda has not increased the displacement of the 13B rotary
since 1973. It is remarkable that the power per cubic inch
has continued to increase all these years. Perhaps it is time for
slightly larger rotary engine with more torque.

The turbo compound
rotary will set a new standard for low fuel burn in a high
power to weight ratio engine. I had a forum on the subject
at last weeks Sun n Fun and will hold one at OSH in August. I'll
also be submitting a tech paper on same at the Jan meeting of the
AIAA in Reno. The turbo compound gear box is nearly done.
Some pictures later today.

The RX8 is doing well. I would not be a bit surprised if
it is responsible for record profits at Mazda despite an over all
reduction in sales. Mazda is under the gun as long as they
stick to the econo box. They have to break out of that market
like Toyota and Honda did. Both of which have aircraft programs
BTW. Mazda is sitting on the best light aircraft engine
ever. Sure they won't make a lot of money but as
a PR and marketing tool it would be unequaled.

Paul Lamar ...No rotor no motor.


The engine is cool... way cool... the car looks, well, Japanese.
It's a funny looking sports car.  Or I would buy one.
