Paul or Jerry,
Can I have the drawings of the comparisons of different P-port positions.
I know their in distance from the bottom of the housing but I can
convert them to degrees. I need that to check against degrees for Doug
(Japan).

Is this what you need?

BTW notice the lower fuel consumption for a p-port engine in the 80% power
to 100% power range which is the range we run in. Sucking air in takes HP.

I would love to know a) how direct injection affects BSFC on a p-port
engine and b) whether a rotary in aircraft use can really be reliable
when run at 8-9k RPM.

And here's to hoping mazda reconsiders the p-port intake with direct injection.

They ran the Lemans winning p-port engine for a hard 24 hours at 7000 to 8500 RPM average and could not measure the wear.
