Paul,

I followed a link to your website rotaryeng.com <http://rotaryeng.com>
through a video about the 3rd Generation RX7 Speed Test. After perusing
your website, I noticed power output and pictures of a Mazda 16B engine
released in 2007. Do you possibly have any more details or pictures of
this engine as I don't recall any sort of press release from Mazda about
releasing this engine.

Thanks,

Jordan Farber

No word recently. If I were guessing, due to the present cars sales
situation, I would not be a bit surprised if it were on the back burner.

From an engineering point of view I think it is a mistake. It appears
to be an attempt to merely increase the torque. I am sure it will increase the
torque at any given RPM about 23% but that is not much in the overall scheme of things. It may be no better on MPG and it certainly will not increase the peak HP 23%.

IMHO Mazda would be better off with a seven speed  auto or paddle  shift
transmission instead. That would make the RX8 even more fun to drive
than it is now.

If I were in charge of Mazda R&D I would be busting my buns on turbo
compound as that would be a double digit percentage improvement in MPG,
torque AND HP. IMHO turbo compound will be mandatory in the in the not so distant future for all ICE's. The world cannot go on throwing away 50% of
the energy in every gallon of gas burned. Some sort of turbo compound
will happen soon. Thanks to my presentation in Oxford recently the Formula 1 people and the FIA  are already talking about it.

I would also look at a trap door P-port to increase the high end
power of the current engine to about 300 HP with out affecting emissions
or drive ability.
