    I'm lead to believe that the marine spec C12 is 700hp @ 2300rpm. The differences between the highway C12 and marine are camshaft, injectors, turbo and pistons (and obviously the marine engine has better cooling). Would it be fair to say with the correct turbo, injectors and cam, you could reliably squeeze 600-625hp out of a C12 (obviously monitoring temperature gauges)?

    I'm making this presumption based on the performance that can be extracted from the little Series 60..

    Marine in the water is more of a one speed situation driving a reduction gearing and propeller. Plus any other hotel support systems on the ship.

    Trucks take away much of horsies from engine both in hotel load (Alternator, air conditioning, cooling (Heating) etc) and a load impose on a parasite loss of power driving the guts of itself, transmission, rear end and so on.

    You are pretty close and the final HP to Pavement will be at least 560 my estimation. I am not formally schooled in this engineering stuff, just gathered bits and pieces I found useful over the years. Maybe even 600 if your aerodynamic, tires and so on is superior.

    The C12 super engine was about 1300 HP.

    The Mike Ryan race truck is a 14 series 60 making 3500 HP or more.
    Both are race engines.

    Good cold Clean water fresh from the Ocean, or any other body of water can never be replicated by a close cooling system


    I am a a high performance boater of 50 years.

    Heat is Death

    I run a 450hp non- emission Detroit in a glider with a 10 speed maxing out 80 thousand everyday

    What are you hauling that you need more HP

    Paul is the Shinizzle. He grew up running and building single engine sportfishers for day charters

    He started building larger twin engine boats in his back yard in a barn that OutPerformed every boat out there

    A ton on innovation and knowledge there. Paul was light years in front of the commercial boat companies in lightness and rigging setup

    It's a dump and trailer, grossing 110,000 (Australian).. it's currently running at 475. I may just run a Diesel freaks loom and look at repowering it with a 3406/C15 later done the track...

    Screw that Cat. The parts will kill you.

    If you are going to Wind up that Bloody WomBat all you need to remember is COOL is your friend.

    Not Australian. But my closest buddy is. Lost old dear friend from NZ years ago

    So how do you Fockers get your loads across the Ocean.

    They totally HAD IT. But they blew by a weigh station.

    3500.

    I don't know what engineering will accept that much horsies at the axle. Probably some modification of a given Naval type gearing.

    Im kind of sick at our Trucking Industry wallowing along at 500 hp. We really need to get it up there. 1000 would be plenty. Flat the mountains and make time up hill at the speed limit, even if it's 75.
