" They lie :) It is not a Renesis 3 rotor. If it is a
3 rotor it uses old 3 rotor parts and it is a 3
rotor p-port."

They certainly are calling it a "20B Renesis".  While
it may not be side port, side porting would certainly
be possible, particularly with sufficient
turbocharging.  Someone made a really nice CAD-CAM
mockup of a possible design that's really interesting.

"There were rumors for awhile that the IMSA 3 rotor
cars were  using RX8 rotors but even that is in
doubt."

I think someone put a V8 in a BMW 3-series last year,
claiming it WAS a production engine from BMW, just not
available to the public in a 3-series.  Not syre how
they fared on that.  Might be a similar situation with
the 20B they're running, since the basic design of the
20B they're using is probably similar to some older
Mazda rotaries (and of course the Eunos comes from the
factory with a 20B).

" IMHO they lie for the sake of connecting the racing
effort with RX8 sales in the minds of the car buying
public."

Perfectly understandable.  Since they aren't selling
the 20B motor to the public, they're not defrauding
anyone.  I feel like Chrysler using the "Hemi" name is
far more egregious, since there is nothing
hemispherical about ANY combustion chamber that meets
US emissions standards any later than about 1977.

You must realize that most car racing today is not pure car
racing. The rules are adjusted on an individual car basis to
make all race cars, in practice have the same, lap times.

If it were REAL car racing one engine design would dominate
and that is the Wankel rotary engine design due to its superior power
to weight ratio. In fact a minimum car weight rule alone handicaps
the rotary powered race car. At one point in time, in the late 1980's, IMSA rotary
powered cars were required to carry 650 pounds of ballast.
Prior to that the the rotary engine dominated IMSA endurance
racing for a decade.
