um,
no
Displacemnt is measured by the volume of "open"space in the epichrod
with the rotor in it.
They displace 654 cc per rotor (13B)
multipling by 1.4 is merely a tool used by the SCCA to specify Pressure
charged cars vs Naturally aspirated.
It isn't the Rotaries fault that a Piston engine is inferious by basic
design (some comapies have come in leaps and bound in Pston engine
technology ie Honda VTEC)
there are three rotor faces, but the displacment between them is still
654cc (divide that by 3 and that is the per rotor face volume.) you are
mutiplying it by 9 in your calculations
You aren'y being pugniable about all this are you?
I am not, i am simply trying to help you understand the rotary from a
rotorhed.
Take it easy,
Chuck
