what do you think about the B3's vs a single prop XR for speed? We have always had trouble with them in mid 80's and above. The extra prop becomes a drag at higher speeds. He's definitely gonna need XR's but i think getting away from the B3 is gonna help. Pretty heavy boat at almost 15K dry so maybe even an Arneson conversion (thinkin lottery again lol)
Rob (offshoredrillin) has had great luck with the builds Dave did at MGD. Strong turn key stuff and pretty much the most HP i have seen out of an ASM intake. Without introducing wind your just not gonna get much more then that plus you retain all the reliability. I was VERY impressed with Robs motors and what they got out of them.

Offshore Performance does this type of work and engine rebuilds, his advice just rebuild.
You guys might know a thing or two... But Hell, I've never been one to listen and enjoy swimming upstream, so if I know myself those motors are getting built up past 600HP and see what happens.
Lets get this 370 to 80MPH!!!!!!

OD has a point, when one thing gets pumped up it affects another downstream. Nothing's worse than having a boat in the yard sitting for service when the summer is flying by. I've never done anything to my boats that reliability hasn't been the #1 factor up front.

ALL ELSE BEING EQUAL...
Obviously the B3's aren't going to survive a ton more hp or speed. Assuming all the data you gave us is spot on, and your stock 500efis are putting out 470hp to make 62.6, doing the bar napkin math with the current set-up, this is what it would look like...
If you want to touch 70, the math says you're going to need about 610-625hp a side.
If you want to touch 80, you're going to need about 800hp a side,
If you want to touch 90, Cough up enough cash to make around 1050hp a side
If you want to touch 100, 1350 a side MINIMUM to get you there...
And if you won the lottery and were really interested in being stupid (and could figure out how to make them fit) a pair of 1650's would get you up around 110-115mph. No promises on these numbers or what the ride would be like at that speed! I can't even begin to guess what the max the transom would accept before needing a little reinforcement...
Of course, what you do with your drives is going to have a huge effect. Rik from Arneson can probably help you with the numbers for the increased efficiency of their drives.

You wont like that boat without B3's or duoprops. They cant be beat for getting a boat that size and weight out of the water. Have Eddie Young build you 2x625's out of your motors and stick with the B3's. 70mph out of that rig would be impressive.

Very nice this is what im looking for, the BS aside how do you think a 610-625 hp motor will hold up? If i run it nice mostly at cruise and open her up couple time a trip will the engines see 500 hrs before another rebuild??? Withthe additional HP what type of torque is expected and max rpm? Would a different prop size and pitch be recommended?

You test that with an ultralight and a long strip of canvas!
LOL!
Now, if you're flying an LOC BC approach, inverted, and the needle is moving to the right, which way do you move the yoke?
