Picked up another project

That's good to hear. I don't much diesel knowledge for high horsepower building. My kid (37yoa) essentially said what you say here. Makes me feel better. Yes, he's already scrounging for items, putting feelers out.
He got the boat and trailer for free; but he's going to have to do some fab work for Curtis in the future.

It’s not real expensive either, but in your case I see a 5k-7k compound turbo setup and 3k or so for the injector for each one. Everything else is pretty straight forward. As boat engines, you can also take advantage of water to air inter coolers. If I remember correctly your son has some pretty good fabrication skills that will come in handy on a project like that.

I’m no stranger to going fast in a boat, this was my first whitewater marathon boat, 447” Donovan hemi alcohol injected and supercharged around 1600 hp, I gotta dig the pictures out, you can see the block peaking out in the third picture in the garage that went into the second boat, that engine was a 526” KB second gen. Hemi, injected alcohol with a 1471 blower, around 2000 hp. These were marathon boats that ran rivers during runoff in the mountains, like the Rogue in Oregon and the salmon in Idaho. Top speed around 120-130 depending on conditions. Now days unlimited class uses helicopter turbines. I started my own business and that was the end of all the racing. No time after that.
 
Nothing wrong with the 6.7 after the emissions crap is removed. It’s a bigger engine but a lot more expensive to put on a p7100 injection pump as it’s a common rail, with electrical fired injectors, I think you use 24 valve injectors and cross tubes to go to a mechanical injection pump. Then there is availability and cost.

Son is talking with D&J about this. He suggested the 6.7 for the boat motors. With a powerglide behind them to keep the rpms down.
 
Powerglide final is still 1:1 and with the torque they make you don’t need a 2 speed, my thought on that is it’s just something else to break. Only benefit from where I sit is reverse.
 
A glide will take a lot of power, and you have plenty of cold water to keep it cool so if it’s cheaper than the appropriate crash box, why not.
 
After thinking about it for a minute, I think a used Lenco with reverser would be stronger than the glide and probably cheaper too. Go to racingjunk.com
 
The injection pump showed up today, tomorrow after chores I have a job walk, so may or may not work on it, Saturday I have a family outing, so maybe Sunday I can get back on it. This time I’m doing all the modifications on the bench incase somthing else shows it’s ugly head.

What's your thoughts on a 6.7 Cummins?

Researched modifying the 6.7 some out of curiosity, it’s very easy to get 500 hp with it, as it’s just a tune, where with a 12 or 24. valve it’s going to be a turbo, delivery valves and injectors = couple thousand dollars
And the same couple thousand plus head studs, rod bolts and valve springs and another upgrade on the turbos by adding one to make a compound set up, about 4k so around 6k for a reliable 1000 hp
6.7 is going to need turbos, the bottom end treatment, injection pump , injectors and a tune. The difference is the parts cost is astronomical compared to a mechanical pump. So 6.7 around 20k to get to 1000hp
Both are assuming you already had either engine. It’s been my personal experience racing a boat, that electronics on a boat are not a good deal. Start a thread on your boat build.
 
He's doing OK. He obtained a quote for 1200 hp 6.7, minus the turbos and exhaust work (that's what he does), was 50k each with Bosch computers being 25k of the 100k! We have a lot of research ahead of us.
The boat originally had 825hp diesels in it and it did 120mph.
Still waiting for the NRE engines for Plain Vanilla. Supposed to be soon. The cranks is what held it up.
 
What’s the reliability and longevity like sucking that many ponies out of such a small engine? Seems like getting more than 600 out of 15 liter engines starts to cause problems, but maybe it’s the heat created that is the problem with land locked engines, not an issue with one running in cold water?
 
Plenty of cold water.
Thermostatic oil coolers.
Jacketed tugbos and exhaust pipes.
Actually have to have relief valves on the cooling system, jamming cold water in through the pickups at 100+ mph build up alot of pressure
