Wow, I had not even considered the RX-8, but you are right about the bridge port. No overlap so it can open early and the bridge ports can be quite wide too so they will have lots of capacity. This may be the ultimate engine. Jerry
Ps. George I am looking forward to plugging one of your bell housings into my fixture. Are you going to deliver the castings with the mill work done or will that be up to the builder?

Jerry,
Here's the latest - my design for the Rx8 P-Port.
It is a bridged P-port as the Rx8 apex seals are very narrow and flexible -
not to be used with P-exhaust housings , for obvious reasons.
The green circle is your 1.6 PP.

Suddenly there is a lot of interest in P ports. I think at least 6
different versions are being built or at least dreamed about. There is
one mentioned yesterday on the other list that will basically be a race
engine: 300 hp at 9000 rpm!! Trouble with that number is that it does
not compute. I think 400 hp at 9000 rpm would be more like it. This
is a different world from the wimpy little 220 hp at 6000 rpm engine I
am building.
Anyway, last week I posted a drawing of the intake plenum I planned
to build but since then it has gotten a lot better. Here is the new
version. The air filter goes where the alternator was located on the
stock engine. Jerry
