The anti-auto (or truck) engine crowd will never admit that one of these

the "they never run at full output in autos" way of thinking.

I still would rather get in an auto engine conversion airplane that has had
the bugs worked out, than any airplane with a rotax engine of any size.

There is a fundamental problem, any auto engine is designed to deliver
purely rotational power from the crankshaft to the transmission.
In aero applications the prop is applying the entire power of the engine
trying to pull the crankshaft forward out of the block. That needs some
serious thrust bearings which auto engines simply do not have.
Which is a TOTAL nonissue on most auto conversions

Get used to it.

He's wrong a lot.
