wow..... Wonder if you put that in your truck what the mpg would be! Me... 2... Tires. gone.... Transmission. Back there some where..... Engine. Right besides me because I was going to fast and missed the corner. Long story short.

21.6 gals an hour

umm... that doesn't sound very economical. But it does sound fun!

Those marine diesels are über expensive. I do a lot of boating on Chesapeake Bay, and a guy I know has a 38' Tiara (model 3800 Open) with twin Cummins QSC8.3s, which I think are 490 hp. It's fast for a 20,000-lb boat, but I thinkit cost over $400K.

How much different are the rods etc on this motor?

it's amazing what can be done with a different cam grind, injectors, turbo and higher compression. . .OH BTW, the pistons are probably ceramic and tefloncoated.

the main reason you can get that much power is you have the availability to unlimited cool water. . .no air to water radiator to worry about.
