he thinks the setup they have produces a much stronger and higher reving engine than the current titanium valves they use in some of their race engines. But he was saying the slight sideways movement from the cam force causes the valve to snap along the stem at ultra high revs because of the stem seal.
Perhaps this is why they don't rev the titanium valves as highly and hence don't produce as much power? If it was so much stronger, why would the valves snap? If it is producing better power due to good thermal insulation properties, maybe try coating titanium valves with ceramics or sometimes I think they use tungsten??
