Looking good.....how much hp you gonna be running? What prop are you thinking about running?
|
That is a sweet looking engine you got there.
You originally said somewhere around 650hp, so depending on what kind of speed you are shooting for, a 30p Labbed Bravo 1 should put you right at 90mph at 6000rpm, depending on your prop depth of course. |

I dont know about that.... Don't quote me on this but I am pretty sure that Don's 29' is putting out a bit over 650hp and has run a best of just over 90mph with a very high X at 6000rpm. I would think that a solid 700hp would run mid 90's, maybe high 90's on a perfect day.
But could be possible with a very light load and perfect set up. |
This boat is built pretty heavy...but its also a bare bones boat. Were actually going to detune the motor just a bit because of the 75 mph restrictions...were thinking more like 550 hp and 6000 now for a longer living torquey motor...the X is real hihg on this boat.

But could be possible with a very light load and perfect set up. MRD said the motor was 750hp with there race cam, They detuned it for pleasure boating but didn't re dyno it. They guessed 625-650 hp They said it was a 509, well its apart and has a Crower 4.125 crank rods and .Ross pistons in it (no stamp on the pistons I need to measure the bore).... so a little over 509... . I agree I think mid 90's with the right setup will take 700hp. I have a documented 800+ hp that ran 98 mph and 104 when he put a much needed larger carb on it. But the X is a little deep and the prop is not labbed yet. So in my opinion 650 hp 90, 700 mid 90's 800 hp 105 mph. 1000+ hp we will see |
