Are there any O-200 engine modifications that increase performance. I don't really want
to see my C-150 at 150 mph, but it's fun to dream.


There are lots of O-200 mods to increase performance. Get yourself
to the Reno air races and check out the Formula 1 class. The best I
heard was the O-200 on Pushy Galore. It was supposed to be putting
out something in the neighborhood of 225 hp. On the downside, the TBO
is probably about 50 hrs.

Of course, if you're looking for mods that would be legal on a
C-150, that's another story altogether. Even dropping a 150 hp O-320
(legal STC mod) will not make it go 150 mph.
