Not sure how close intakes were before, didn't ask, I know they match perfect now lol

Not sure on dyno yet, if I have time I will do one, but it's looking like time and $ may not be there to do so, might be god dyno session in may lol

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.

I'd bet he'll be a little over 5,800. Still a big improvement over 5,500.
