Just a quick update.
We finished the drivability. Everything worked great. We attempted to make an easy pull to only 5800 rpm. However, it rapidly ran out of fuel pump. With less than 7 psi of boost and only 5800 rpm, it still managed to make over 950 hp. We are headed back on the dyno in the am with a Weldon pump so we can pull it to where it needs to be.....about 6200-6300 rpm. I was trying an Aeromotive Eliminator pump. They have an Aeromotive A1000 in the boat now. The Eliminator is quite a bit larger than the A1000, so there is NO way the pump in the boat is even close to being large enough. I'm sure that contributed to some problems in the past.
I'll keep you guys posted as we make some pulls.

If this is an EFI setup (I can't recall), even one A1000/engine will probably not be enough. If carbs, a single A1000/engine should easily support 1000+ hp... Assuming everything else in the fuel system is up to par.
Glad to see this is all coming together for summer!!!
