Hi Paul,
on that Mazda video on YouTube about rotary engine production they make
mention of a 16b with aluminum side housings as a future project.
It refers to increasing the capacity by increasing the "stroke". I
guess they mean increasing the eccentric distance. Most of us thought
that the ideal would be to increase the rotor width to 100 mm. Do you
know anything of this?
BR, Dave McC
I can't find anybody that will admit to anything. If they do increase "e"
it might be for a higher compression ratio. They do tell me wider rotors
(100 mm) are out. Too bad as the new engines will have all new parts.
I would just be ecstatic if it was all aluminum.

Hi Paul,
well just be ecstatic then,

Doug can you go and take some pictures for us? If not you will have
to put up with Robin and I again. Also please find out what the e and the R is.

Here are a few guess's.
Rotor the same width (80 MM) outside width +1 inch to 13 5/8
I am surprised. I would think a wider rotor would give a better
combustion chamber shape. Looks like they just scaled it up in 2D :)
Outside height to + 1.5 to 14 inches less the direct injectors.
e/R looks the same. My guess is high RPM is now going to be more
of a problem. They may reduce the red line. consequently max power with
a p-port ataround 10,000 RPM will be down. Too bad. If I were doing it
would go wider rotor and use an aux P-port.
Max power p-port at 7500 RPM should be up to about 285 HP.
Great for the tilt rotor VTOL.
Perhaps wider would be a problem for the phasing gears.
Well one up side it will fit in an RX8 with minimal changes :)
Should plug right in to an RX8 car.
Weight about 185 +/- 5 pounds. Not much less than the current RX8 motor
despite the aluminum end housings.
