I like the P-Port design over the Renesis:

  With the superior breathing of the P-Port, you WILL get more power
at any altitude.

  Designing a LASTING exhaust system on the Renesis may be easier
because of the reduced energy in the exhaust, but the manifold is more
complex (three rectangular ports), so building may be harder.

  With the manufacture of the slide throttle, the P-Port + intake
will be much easier to manufacture than a Renesis intake. Also easier
to modify length for tuning.

  The P-Port is a high rpm design and takes the 2.85 PSRU like the Renesis.

  The P-Port has the possibilities of adding more rotors (20b) with
minimal design changes to the systems.

 The more panes we get flying on a common design the more we will be
able to make precise recommendations to builders. Paul as created and
collected an amazing amount of information.

 I do like that there are people doing Renesis builds. I hope they
get together and document their installations.


 Paul/ACRE is getting much closer to having a full set of standards
for the 13b P-Port install.
It would be cool to have an exploded view with a bunch of the options available.

cooling design criteria and reference designs
Schertz Beam, the oil pan plate thingy
slide throttle & drip slide throttle
twin injector bosses
muffler designs. I would like to see one proven
modification to the water pump housing
light weight alternator mount design
Tracy's engine management and PSRUs
reference fuel system designs.
not to mention the little things, remote oil filter, spark plugs,
coils/ignition systems.
