If and when Mazda comes out with the RX9 it will be challenge
installing it in an airplane. Here are some 3D's I did. This is the Big GT40 TC we used
on the time to climb. Should be about 900 HP. Enough to win at Reno.

It will get a lot easier if you move the engine 4 or 5 inches further
forward.  You might have to add a P51 style strake ahead of the
rudder to restore the direction stability. Our pilot has not
mentioned a directionally stability problem yet with the TTC.

Everything after RX9-15 is 5 inches forward.

This is just rough at this point and I will do another exhaust
manifold to make it easier o get the motor mount tubes in there.
