I suspect you will be ok. I don't know if those are waste gated turbos or not, it sounds like maybe not?

I did a little counter rotating prop specification last year, working with an OEM. I seem to recall that extreme pitch ratios are less efficient, generally speaking. I seem to recall P/D in the 1.2-1.6 as desirable. I think that a 26P hasn't gotten so far in P/D ratio as to be a concern.

Bravo 3 props are stainless only, I am told. Based on the local prop shop, he isn't a fan of stainless for modification, he has seen too many shed blades!

But it seems like a bravo 3 at the standard 22" pitch probably is a good starting point. But it might still be slow over the hump, depending on the turbocharger trim.

Edit: I strongly suspect you have the 230HP waste gated model. I still think 22" is a good place to start for pitch.
