Hi Jerry, my p-port opens the same as the LeMans
with also 1,5 opening, and still idles fine with just the carb. I am looking at
closing it later than it is now for the final tuning, but I do not plan to open
it any later. Believe me, I was surprised when I saw the engine run like that
the first time. I think on the 13B housing(12A is running now) it looks like a
2" round port will give me about the same
characteristics.
How far are you away from running your
engine?

Hi Richard, my p port opens much later than the Leman's and it
closes about the same. It is 1.5 dia so obviously it cannot match the plus two
inch of the Leman's port as far as timing is concerned. If you want the actual
degree for the opening and closing events I can dig them out for you no
problem. I admire your work and intend to copy the one rotor next year.

Paul, all the
companies you list sell housings with BIG p - ports and massive overlap.
They are designed to develop tremendous hp at high rpm for racing. Of course
they don't idle smoothly. These engines have nothing to do with the smaller,
conservatively timed p ports that we wish to use as aircraft engines.

Jerry,
what
are you calling consevatively timed p-ports?
Just
