Reid this is just what you need . Better jump on it . It looks cheep .

Ford turbo Big Block

Turbos are awsome:) but a supercharger would be 500 times easier in a boat because you could still run the water through the manifolds. There was a vortech stetup on Ebay not to long ago for ford marine engines:)

i think it would convert it to steam, the water would not cool it fast enough,I cant remember on the diesel boats on how the water would bypass the turbo's, but it did, we had 3 engines with twin turbo chargers, we could not get the boat out of the hole we tried everything, the engines would come up to about 1200 rpms and stay there and blow smoke. Finally what we did is we ran 3 air vent tubes down to the top side of the props to airiate the props, when those turbos spooled up you thought you were in the space shuttle

too bad its not a chevy...

Tull, If you look at this picture, you will see that the cooling water running through the manifolds is bypassed around the turbos to the exhaust riser with the short piece of hose. No water through the tubos.

For sustained runs the turbo is an excellent choice but not for ski boats, in a ski boat a super charger is the way to got as 79 said earlier, the turbo lag is problem. a turbo charger doesnt have the ability to compress air as does a roots type supercharger, because of this you want to run low compression pistons because it kicks up the compression ratio, a rotary screw air compressor is a good example of a roots type compressor if you are familier with them

Not that I would even consider it, but wouldn't that thing make ungodly amounts of heat and pretty much cook an engine box, or no? I see it moreso in a I/O boat with a large engine compartment or maybe a flatbottom exposed-engine scenario.

And Joe, while I'm with you 100% on the torque, I still see it possibly being a slug out of the hole, as you're gonna prop it larger for the max rpm gains resulting from the turbos. In a car you have the benefit of multiple gears to compensate. Interesting.

Why would you have to make it reverse rotation ?
Get a Classic with the steering on the left side . Or a 1:23 - 1 trans and prop it right .

Alot. We did 6...do I hear 8?

Sorry John, but no ski pole in the Classic, go figure. So what would we tie the ropes to, Backfoot100 Eddie's forearm maybe? But then he couldn't be one of the footers.

Joe, I WAS hoping 340-350, but I feel the boat would be running faster if so, and that's why I dropped my estimate. The engine made 320-335 in a car back when, and I've got the same .480-490 lift cam spec as the 335hp model, plus an intake and slightly better heads and same 10.5 CR. The boat supposedly does weigh about 2400 based on a 'cuda, but I've never seen an actual Classic weight in print. We're still tinkering however, but I'm trying to contain myself from beating on it like we do the Mustang.

Reid   I would suppose with 650 hp. you would be pushing close to 102 mph . If my educated guess is right . I figure double hp. = double mph.


But then again I did graduate 5th grade.

Score one for MM!

He needs no encouragement.
