I plan on picking it up monday. 76bonneville said I needed an investment, thanks Ron! plans are to put a bbf in her. make a 2 seater river racer. what kind of power do i need for a good mph, 80s would be nice to start. Dont know much about the performance of this hull or if big mph is possible out of this boat. has a berk JG with a hyd. diverter. dont know about the internals yet. what can I expect for MPH with decent power? is there any specifics that the hull likes to go fast? i.e shoe, ride plate, etc. thanks for any help. looking forward to this build ;D

It's all a crapshoot of trial and error, my recomendation would be to chase down someone who has the same hull and find out what did and did not work, might save you some grief, not to mention some dough! :D
Some hulls respond to every "bolt on" you can throw at them, some don't, some respond to weight distribution, some don't, I think as long as things are proper i.e; bottom blueprinting, motor and pump placement, horsepower and wot rpm (matching to pump work), and overall rigging, 80mph can be attained without building a NASA spec machine, but everything has to be at least close.
It all boils down to homework and money.
BTW don't forget the specs and pics Monday ::)
See Ya!

Start throwing money at it till it stops gaining speed!

Pretty sure that's a Custom sprint.... the Super Jets are wider in the back, and that one looks pretty narrow.... I wonder why I know this ::) ;D
Add a droop, longer rider plate and shoe if it has it. If it has an original Sanger intake in it, I'm not exactly sure what the process is for cutting for a shoe and rideplate, cause they are installed from the bottom, instead of the top.

I got the interior and the carpet ripper out last night. The floor cleaned up really nice with a little acetone. need to lay a little glass down on the sub floor by the seats for some strength. Ive been going back and forth with lucky stiffie with the seats. I need a good way to mound them on a flat surface. They need to be as low as possible to. Im 6'2" and look like im sitting on top of the boat with the stock seats. coming along though. engine goes to the shop next week sometime to get a good look through.

A friend of mine has something similar to this in is Kona that has a flat floor, the bottom one...works great spins the seat around when hes just floating down river.

So the guy whop is building my motor talked me into 1 large turbo hanging off the back! good idea or bad? its going to be a river racer hopefully!
-
Are you planning to use EFI (spendy $$$$) ? I have never had good luck with carbed turbos (tuning nightmare !!), but others may disagree :-\ .
-
I agree
Blower + Carb
EFI + Turbo
Though once you tune a turbo carbed deal, you can tune anything..
-
a good friend of mine (also the motor builder) assures me its no problem to tune. I think Im going to run 1 large turbo over the standard twin turbos.
