The real dyno will be in the water anyway. Assuming your going to start off with same props so you'll have a good comparison and with your afr wideband it will be easy to tune on the water. Wonder how much jetting will change. You've got a lot to look forward to anyway.

Yes the plan is to keep the same property permanently I only spun them to 5500 last year they go from the very beginning two years ago was to push the same propellers to 58800 or 6000 range, if I am get them to that range I will be extremely happy.

If you were turning a 25p mirage, to 5500 last year, and 72.5 mph, thats about 16% slip. Simply being able to turn them to 5800, would net 77mph, and 6000rpm, would net 80mph.
I wanna say, the general rule, is about 20-25hp, per 100rpm. In order to gain 500RPM, you need to be making around 100hp more than last year, per side. Which would make sense to me, because I would think, that a pair of 725hp mills, in your mistress, would net around 80mph in real world numbers, with a TRS setup.
At this point, Im sure you'll be happy with any speed gains, and of course, reliability.
