We now have Mazdatrix dyno runs on the 2 inch steel tube welded RX8
   p-port
   engine.

   Far more torque and HP than the RX8 high power engine in the
   6000 to 7500 RPM range. This is the range we use with the 2.85:1 PSRU.
   This had a 52 mm Weber carb which unfortunately is smaller
   than the 58 mm Weber carb we used on the 2nd gen p-port engine
   dyno runs. The 52 mm carb is showing signs of being too small.

   The 2nd gen P-port engine is now running in Mark Suspinski
   Mustang II. Hopefully that will fly soon.

   Dave Lemon commented that the engine had extraordinary stand off
   fuel/air mist
   above the carb with the stock RX8 exhaust manifold. This is to be
   expected
   as organ tuned p-ports don't like exhaust back pressure. We use ram
   air plenum's
   so this is not a problem for us. A supercharger exhaust manifold and
   stright through
   muffler reduced the stand off and increased the power. Dyno run B.

   More pictures on Monday and perhaps a video of the engine running on
   the dyno.

Looks great!  The side exhaust doesn't seem to be hurting too much..


Matt-

I am relieved about that too :)
