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.

Kinda where I am at in thought process and speeds, to be honest if it goes 75+ and stays together for a few winters would be nice, I had no issues last season as far as blowing them up, just not happy with performance and findings as we know, to see 80 in a mistress with 3's takes right about 700 HP, I am not sure on TRS, fastest TRS Mistress I know of was Cigrockets at 75 with TRS spinning 27 Mirage plus I think@5300 rpm with 678 dyno HP... so I should be happy I hope.... Billy Andersons Mistress with 730 ish HP went 81-82 with 3's

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. |
me too bud, I hope so ... I really dialed in the parts I had... the exhaust will be only limiting factor I think, and we will see what it does..

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

Another reason I sent Smitty my carb, to see where it compared to a Dominator, also with and without arrestor, glad to see it's not going to kill me..

wrong ratio, and still need all, the rest, if I change at all I would buy a whole boat for parts..
