Paul,

The image  left-side-p-port.jpg (attached) of Mark Supinsky Mustang
II P-port 13b left side shows P-port with slide throttle as per
rotaryeng.net website and a short exhaust.

The image p-port-turbo.jpg (attached) shows the short exhaust
replaced with a turbo and feeding back into P-port  top chamber.

Principally are these the major hardware changes needed to add turbo
to a p-ported  engine.

Yes and here are some pictures of the turbo integrated inter-cooler
and p-port intake manifold my welder welded up for Mike Collier's
Long Ez. This will be an easy 300 HP or more. It requires a
butterfly throttle between the turbo and the inter cooler.

The new Borg Warner EFR turbo would be a simplified fit . Divided SS
turbine housing with integrated waste gates. Also boost control and
BOV all in one small package. This one is the 8374... good for about
400 HP take off. Barry Bordes

Barry, where did that Rotary exhaust manifold come from?

The turbine blades may not work for an aircraft rotary engine. A Renesis may
have cool enough exhaust temperature running LOP.  I think a greater use for
aircraft would be to use the TiAl to copy the turbine housing as that would
reduce the weight considerably.  The outside is exposed to the air to cool
it, and could have a duct blowing air over it to boost cooling Another
thought; suppose air was introduced between the turbine and the center
housing or a small hole was drilled in the center of the turbine and radial
holes were drilled at the base of the blades.  An Inconel tube ducting a
small bit of air from the compressor output side would cool the turbine.

Hollow blades are a common way of cooling turbines.
