I was thinking along the lines of using that when engines get modded from stock form. Getting vibe info would be great to know how the new parts or tunes are doing in the engine during the combustion process. On aircraft, this can even help maintain A/C generator (alternator).

Thanks for the explanations. What design compromises did Honda engine use to make power on higher RPM like that? I see that it is a very tall motor.
