80 mph + 24' Superboat (continued from Pantera Forum)

We're set to do the full dyno pulls on Monday. Brad had to get the fuel system in order and didn't have all of the parts. He should have them Monday morning, so we should have numbers Monday afternoon. I'm going to takes some pics and video for posting.

Ok, it was a little lower than hoped, but still pretty good considering. We hit 501.3hp @ 5200 rpm & 535.7 lb*ft of torque @ 4629 rpm. The torque curve is pretty much flat after 3000 to 3500 rpm. This is going to be an accelerating monster! I think we ran out of intake manifold, because the horsepower went flat at about 5200 rpm and didn't fall off for a while. I guess I can only expect so much from the stock manifold. I've attached the dyno sheets as well as the links for some videos. Can't wait to get it back together and try it out this weekend!

Looks great to me...
There are mods that can be done to the manifold to shorten the runners; probably not worth it at this point though.
I'd prop for 5300-5400rpm. Most of the prop gurus say that you want to be at least 1000rpm over peek toque.
My guess is that you will be in between a 26p and 28p B1.
Maybe try the 28p first.
