It is my understanding (but I can be wrong) that detonation usually
destroys an engine *quickly*. We are talking here about minutes, if not
seconds. If an engine lasts a few dozen hours, you can be pretty sure
that detonation is not in the equation, or am I wrong here?
If an engine that lasted a few dozen hours suddenly gets destroyed due
to detonation, there is usually a reason for it. An ignition timing that
went off time, a fuel mixture that went to lean (clogged fuel filter or
carb?) a sudden rise in boost pressure (are you sure you didn't
experience a sticky waste gate?), etc.
I think it is unlikely that Euro 95 is able to destroy a Rotax 914
*slowly*. But of course if someone can explain me how this is possible,
I would be gratefull. I don't want to destroy my 914 after all! ;-)
