Paul is the RX8 happy to be turbocharged? Should and can the compression
be reduced easily. Could the rotor have a little of the convex shape
shaved off to reduce compression? Or the bowl enlarged?
Mark Dillner

If you put Ianetti ceramic apex seals in it you don't need to reduce
the compression ratio. The stock apex iron seals can run up to 500 F at
their center. That can go much higher when boosted and may fail
the seal.  The ceramic seals will go to 1000 F.

The same material is used in ball bearings that are good to 1000 F
while steel ball bearings have a 500 F limit. Most ball bearings in
F1 race cars are ceramic.

In that case we have seen 85 inches of Mercury manifold pressure
so far with no damage. Something like 700 HP. The Wankel is amazing!

An air cycle turbo expander. Cool idea made into hardware; English, not
American.

"A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial flow turbine  through which a high pressure  gas  is expanded to produce work that is often used to drive a compressor "

Are you suggesting this be used to cool the apex seal?
