Ferrari Mailing List: Re: Cool Ferrari Christmas present

OK, talked to a friend that builds racing
engines.  Titanium valves have issues
at temps above 1250degF.  This explains
the engine failures in my ex-father-in-law's
turbo boat engine.  Apparently there are
some titanium valves with hi-temp coatings,
and more hardy titanium alloys, but the mass
advantages of either are minimal over a
stainless steel valve.

Maybe an alloy with some titanium, but it is
considerably heavier than a much larger
titanium valve for a small block Chevy.
