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.

   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).
