Here is a picture of the P-Port solution on the one-rotor. I put an

AL

plug in the unused tension bolt hole and threaded a stud in. I also use

the

exhaust bolt for the intake flansh. This insert will never come out

with

the intake in place.

The exhaust is mounted with a 4-bolt flange.

Richard,
Where did you place your ports - directly opposite the original port

opening

in the cast iron housings?

George,
My P-Port is opening earlier then the side port and closing later. I don't
want to play any numbers before I have at least some running results. I
believe, at least in the case of a 12A rotor housing, the increase of total
port area over the two side ports or one P-Port will be a considerable
contributor to the achievable power levels.
The answers will have to wait until full power runs on a dyno.
