Patrick engages in complete and uninformed speculation:
The question that has not been answered is the reliability of the 912S
against the 914. Remember that the 914 is a turbo charged 912 whilst the
912 S
is a 912 with a much enhanced compession ratio, leading, all things
being equal
to much greater stress on all engine components. The 914 has not been in
operation long enough to give proper comparisons but I suspect that the
914,
properly maintained and operated with proper care will prove the much
longer
lasting engine.
The actual data is completely the opposite. Just pay attention to any of
the long discussion on this group
for years now on reliability problems with the turbo and overheating and
many other problems.
Meanwhile the TBO on the 912S has been increased. While cheapskates look
to buy the 3rd party piston
set to convert a 912 into a 912S, the factory mods include many
engineering change to support as you say
"a much enhanced compression ratio" of 20%.
Patrick, if you have a question ask it. If you are clueless, don't
decrease the SNR in this group
