If you are running B-1's, what is wrong with 13% slip? What 8% slip says to me is that your drives were to deep.

Brett just did a pair of Bravo 1s for me.I gained about 2-3mph at 3000 rpm,acceleration from 3000-5000 rpms is a lot better,top end is about the same as my 3 blade turbo vectors. I 'm pretty happy with the outcome,and the props look awesome.

Makes sense ....
Does that explain the additional RPMs which are gained with labbing,
or is the RPM increase due to the actual thinning of the blades?

That accounts for some of it. The rpm gain is from a lot of little things that when added up are noticeable.

The thinning of the blades adds a little rpm but thinning the blades is only part of the entire process.

I think we have talked about this before . Dont know your speeds but it seems the faster the more slip. I have been thinking of trying throttle up barracuda props might work for you as well they are a well rounded prop from what I have read. If you can I would try a 1" spacer.
