You’re probably correct about the
time period, George.
However, if you take the CC increase, the
torque increase across the entire rpm range (as you indicated) and the lighter
weight, there is no question in my mind that its going to be a significant
improvement for aircraft. I calculated that it should put out close to 220 HP
at a little over 6500 rpm. Perhaps more important, you can swing a larger (or
additional blades) on a prop for more low airspeed performance given the
additional torque from the engine.
You are correct, thought, until we
actually get one of the beast in our hands, its all speculation. If its much
over 5 years, I may just have to convert to a Renesis {:>)

From what I've read, and taking the current economic climate
and their effect of car sales,into consideration, I suspect it will be
another five or six years away.
I don't believe the engine will be much more powerful but
torqier with the larger stroke. The design will be slanted toward pollution
control, rather than extra power, as evidence by the narrowing of the rotor to
retain more heat in the combustion chamber, for more complete fuel burn.
Some suggest for better power a wider rotor (combustion
chamber) would be better suited to our needs as in the Aixro (spelling ?)
go-cart motor - which has had some success in micro-light
aircraft requiring up to 50 hp.
Personally I unsure, but the proof will be in the finished
product.

Thanks, Bob
I really like this part :
A fundamental part of
Mazda's heritage, the gasoline rotary engine, will be substantially upgraded in
the early 2010s. Currently referred to as the 16X, the next rotary engine will
offer substantially improved performance and economy through use of Direct
Injection Spark Ignition and high-speed combustion technology, enfolded in new
rotary dimensions.
Early 2010’s? I guess that might
include 2011? That was another sources estimate. Well, if that
happens, then my next rotary transplant will be the 16B – can’t
wait.
