We have the same prop you have, Steve. Apparently the 2013 version is the upgraded version of the 200.

You're talking about the 74RV, kweerbayt.
Call WW, I talked to them about it quite a bit. It was optimized for the 195+ HP motors, takes 210 or more to see a notable gain. About 2-3 knots faster top end on an RV-8 from what they said.
Good luck getting them to paint it purple.

I did some checking a while back, as I was thinking I might gain some speed for the races. But found out I may not see much change as I don't have 200hp. It is made for the higher horsepower 360's. So couldn't justify the cost for a "maybe" increase of a kt or 2.

I bet Bob Axsom would be interested in 2 kts.
I wonder if we could get WW to allow Bob to test one and report the results. They could not get a better test engineer.

I have the new version 200RV (with the scimitar tips) being turned by a 195 hp IO-375. I am getting a max speed of 181 KTAS with everything to the wall. I'm still working out little parasite drag gremlins here and there before I get my -8 painted. I'm wondering how fast it will go with paint and the gaps taped over. I'm hoping to race this bird someday--will let you know.

For the record, my last post was edited by a moderator for an "expletive." The wording that was removed was the term "balls to the wall." I can understand how this can be misunderstood as crude language; it's a common mistake. This term has absolutely nothing to do with genitalia. It was a term used in WWII by bomber pilots when they pushed all the levers as far forward as possible--to the wall. Their cockpit throttle levers all had ball shaped grips on the end of them.
I use the term for two reasons. 1) it's vocabulary that's part of our aviation heritage, and 2) it was taught to me by my grandfather who was one of those bomber pilots (a true gentleman who I hold in high regard that never uses profanity of any sort).
Anyway, no hard feelings for the moderator edit. I just thought I'd clear the air on the real origin of "balls to the wall."

Thanks for the history lesson! I always wondered where that came from.
