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.
