you are definately in need of a laxative.

If you'd ever flown an O-200 you would realise that you are wrong.
did you know that at 4,000rpm they deliver 150hp.


What diameter of prop can you turn at 4000 rpm?

A Volkswagen is NOT a good direct drive aircraft engine because it
produces good power at 3200 to 3800 rpm. But it's a hell of a lot
easier to put a redrive on a VW than an O-200.

What is TBO of a O-200 at 4000 rpm?

Except for a very esoteric and crowd-unappealing, masturbatory sport
of F1 air racing no one is going to turn a O-200 at these RPMs. So you
are talking smack.
