Dave:
I agree with you 100% regarding the excessive displacement penalty for
rotaries.
I assume Jim was being sarcastic, and expressing a similar opinion.
Please "stifle" re: the 2-stroke advantage. I hope to make good use of that
at some time in the future (as others have done). Potential for
350-450hp/liter, NA on gasoline.
And I just love the way the 2-stroke sound irritates the hard-core 4-stroke
folks!

Don't get me started on the rotary thing again.. The 3x factor is grossly
unfair
as it is not used by any other sanctioning body in the world. They all use
between 2x and 2.1 x as the other folks know how the engine works and why
the 2x
is fair and the 3x is not.. 3x does not describe the air flow and cycles of
air
flow through the engine. Just search the archives on 'Rotary factor' and i
think
you will be able to find around 300 messages about the whole deal..The
engine
has 2 combustion events in 720 degrees just like a 4 cylinder piston
engine..It
is just more efficient at how it is done. The argument went as well about it
being no sense to change the factor because very few are raced in LSR, that
is
also because everyone that might use one can count and know that the factor
is
so unfair at 3x that the possibility of setting a record is hopeless when
you
have to run at such a handicap of 3x to a motorcycle engine that runs heads
up
at 1x.... How come a 2 stroke can run at 1x when it operates like the
rotary??
it combusts the same amount of air and fuel in the same number of degrees
for a
given displacement.
