        Does anyone have the HP/power  graphs for the series 3,4,5
   Mazda rotary
        engines with and without turbos. (Not Twin Turbo)

        RX8 engines just very got hard to get in Aus. (All;Ruperts
   engines are
        gone) The ones he had left were all bought by the same person
   for car
        racing.

        The use the for the engines is for Gyroplane use.

        Regards David

        Here are a few David. Nobody uses the stock intake manifolds for
        aircraft.
        If it were me I would P-port it and be done with it. It is
   cheap and
        easy to do.
        You save money when it comes time to make the intake manifold AND
        you reduce the fuel
        burn at aircraft power levels.  The rotary engine loves p-ports.

   David,
   Keep in mind that those are the curves for the stock turbo (too small),
   stock engine (no porting), stock wastegate controller (about 5psi max),
   and stock computer(no programmability).  They really say noting about
   what the engine is capable of doing (if you are so inclined).

   What happened to those new pictures with the cowl off? :)
   Do I have to go down to your airport with a screw driver? :)

I have only had the lower cowl off once since then, and I forgot the
camera (top half is easy, lower is a pain because of the intersection
fairings).  The lower section is the only part that is significantly
different.  Will try to remember the camera next time.
