I think an RX9 engine right out of the car with little or no mods is
going to blow the minds of the current light air craft people.
Probably less than $10,000 while the cheapest aircraft engine is
$25,000.

No TBO, 400 HP and  smooth as glass.

Here is some preliminary 3D's on installation in a GlasAir retract.

The turbo pokes through the cowl so I will see what it looks like
rotated CCW 90 degrees. In that case it will require a dry sump
pump.

Retracts are the best bet for the RX9 engine as they can make best
use of the 400 HP.

Glasair are quite cheap used. They go a long way back. Sell the Lyc
while it is still worth something (It is not a rotary is it? :-)) and
put in an RX9 engine. They are basically fast airplanes with no
fuselage mods unlike those required for the Lancairs. Plenty of room
in the cowl as well.

Curious Paul, what fuselage mods are required on a Lancair?

Jarrett Johanson



Right at the trailing edge of the wing were it intersects the fuselage there
is severe separation. The Gulf Stream has a fuselage bulge in that area. I
noticed that when we were out in  Cal City at the Gulf Stream junk yard.

The other candidate would be the Express 2000, better gross weight than
Glasair and more room in the cabin.


James C. Reyna

Is that the former Wheeler Express? Kevin Alderman is building one of those.
Lots of room in the cowl.

RX9 report I read said they may need to put a small bubble in the hood. Sports car hoods
are not normally very high so I could not imagine a big problem with an aircraft cowl.
At worst a tubular manifold to move the turbo off to the side and down a bit.
