If you want that much power, I think the parallel valve IO-370 would be a better option.

Is the IO-390 a parallel valve or angle valve engine?

Yes! I read that, and I'm sure I'll be fine with 150 or 160 hp!!

Default Thinking about it

I have a low time io360 angle valve sittin in the corner of hanger and I was thinking about hanging it on the -9.

I'd also be interested if anyone else has tried it and what their feedback was.

Go look at all of the 9As that have flipped.
All except one in Alaska on a gravel rutted runway had O-360's installed....

Default -9

Yea, those nosewheel models with heavy engines do have a nasty record. However, I was specifically referring to the -9, which is the Tailwheel version. Also, post #3 doesn't speak to the original question.

Huh? How does an article recommending against a 180 in a RV9 not apply to a 200 in a 9????

Of course, it is experimental and you may do as you wish. Do your passengers have the same choice and forewarning in the matter?

Default margins

Van owns the margins, I get that. And, I agree with it too.
That being said, it would be nice to hear from -9 owners who are running the 200hp deal. What's their feedback. It really is a simple question. Just trying to get feedback from those who have traveled this road.

"If you want 200HP -9, build up a parallel valve 360. They are easy to bump up to 200HP."

Very True. My Parrallel I-O360 with 9:5:1 Lycon Pistons pumped out 215HP on test
