As I recall Francesco told me they gave up on
titanium rotors.
Too much heat transfer causes a loss of power. Now I
don't
know if a ceramic coating on the titanium rotors
would recover
some of that HP. Titanium rotors should allow the
engine to run
up to 12,000 RPM or so I would guess.

That is a strange answer Paul, titanium has about the lowest thermal
conductivity of all the common structural metals Ti 5, cast iron 28,
carbon steel 27
stainless steel 10 ,alum 100 etc Titanium makes super camping coffee

Wow! Sounds like I got it ass backwards. He mentioned thermal and 
I assumed it was the other way around. Perhaps the tip seals ran too
hot or the surface of the rotors ran too hot. I will have to call 
Francesco and see if he knows more about it.
How about thermal expansion. 
How does ti compare with aluminum?
If the conductivity is low is the distortion high?
