1,660 gallons of heavy fuel oil per hour

And environmentalists complain about our puny little V8s...:rolleyes:

WOW! And we thought replacing head gaskets on a Northstar was a big job.

You know you've got enough engine when you have to use a crane to lift the main bearings. :)

Actually, the replacement for displacement is boost, but you know....

Did you see the size of the turbo on that thing? I guarantee you that somewhere a 16 year old is trying to find one to put on his Civic.

even still

big cubes + boost>puny cubes + boost

people dont seem to get that. we touched on it in the V6 vs V8 for luxury cars. People claimed technology has made V6s as powerful and smooth as V8's but act like the same technology wont benefit a v8

same thing here, a boost will benefit a i4 i6 v6 v8 v10 v12 v16 v1000

start bigger and you have an advantage instead of having to use boost to catch up.

so, there is no replacement for displacement

You're right. I've been saying this for years. I even changed the saying to, "There's no replacement for displacement with technology". In other words, there's no replacement for a larger displacement engine with equal technology. And you're right again, most people still don't get it.

So true. Look at what Ford is doing with its EcoBoost v6, 360hp/420lb-ft torque. That is great power for a v6, way more torque than their n/a 5.0 v8 in the F150 truck.

Then look at their supercharged 5.4 v8 mill in the Mustang Shelby Cobra. 550hp/510lb-ft torque. No replacement for displacement, and that 550hp is on a very conservative factory tune with low boost.

Go online and do some snooping for just how much diesel, #2 bunker fuel, and lube oil the engines used in the marine industry consume. Makes even a 6-71 diesel bus seem like an econobox by comparison - but, obviously, our elected officials at all levels of government have NO idea.......... (except for the states with large seaports.........funny how environmentalism is so selective, isn't it ?)

Bunker fuel is so thick that it has to be preheated to even flow to the boiler spray tips......................

For a tiny bit of insight, I skippered a 48 foot custom motor yacht from 1994 to 2001. She had two Cat3208TA turbodiesels, 375 hp each. At 19 knots she consumed 46 gallons of diesel fuel per hour! The 14kW generator added another 1.5 gph to that............

Find a YouTube of the Whitbread Round The World Race: Drum (Duran Duran's maxi racer.)

Been there, done that.

Well of course that's true. That's obvious. An engine is really nothing more than a giant pump for air and fuel to make fire. The reason boost is the replacement for displacement is because you can get the SAME power from a smaller turbocharged motor than you could from a large V8 years ago. Case in point - my wagon's 350 CID V8 has 180hp. A turbocharged 2.0 liter Cobalt SS makes 260hp. Why? Boost.

Obviously I prefer big NA V8's, but still.

You know you've got enough engine when you have to use a crane to lift the main bearings. :)How about an engine with a diameter that's the same as the fuselage on a Boeing 737?

Used on the Boeing 777, the GE90, depending on configurations, produces 74,000 to 115,000 lbs. of thrust.
