I saw 75 with TRS.
78.6 with Konrads. Fastest was downhill with the dually full of fuel. Good luck with your project. Also the motors ran for 700+ hours before it threw a rod from what I heard. Flawless |

These hulls are terribly inefficient, they ride bow high and you cant use a bunch of trim to get them out of the water as they tend to plow upward instead of pushing forward. I got my n/a 540s to 82 at 5800. I personally think it takes a crazy amount of power to pass that 75mph mark, 50 or 100 wont make much of a difference. 23p props will kill the cruise, if it were me, I would leave the 25s on it and advance the cams 4 deg and just settle. Im still working out the bugs on my new combo, props are difficult to find for #3 so im kind of limited. I have run 89 to date with 40 more cube, way better heads and 10-71 blowers! I was hoping to eventually see 100 but I doubt that will happen, should be a solid low-mid 90s boat

8Sec, what kind of power do you think (or maybe you know) you are making? Where are the drives set?

Someone once said 10grand for each mph increase.

Im running 6# of boost right now, I think they are making a little better than 900 in this trim. Drives are #3 mounted 4.5" from bottom. Im currently running 17.5 x 31 3 blades but have a ton of slippage ( over 20%) |
