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.

great little engine.

But running it that RPM would take the TBO down drastically. I grew up
in Miami, and used to hang around Tamiami airport. All those Pitts
guys used to overspeed their engines like that. And most of them got
around 300 hours before they needed to overhaul their engines.
Those kinds of RPMs are okay for racing and aerobatics, but be ready
for a very early overhaul.

I believe that the Formula 1 racers generally got less TBO than that. I
have no idea how much of that was overspeed vs how much was high power; but
I am pretty sure that an overspeed of 33% on a certified aircraft would
require an overhaul--regardless of the duration. Some of the regular
posters are sure to know the rules on that.
