I guess, maybe. It makes more power than a stock 6.0 and slightly less than a 6.4. With a short rear gear and lots of drive gears it would move anything. What is it? 318/525 or thereabouts? Maybe the same as a 6.0? I forget but regardless, it appears to be very strong.

 

The one in the above link is 268 hp.
About the same as a 7.3, but maybe better TQ line if it came with TT's.

I keep hearing stories of dodge getting diesels in their smaller vehicles, haven't found solid proof yet though.

 

I had a 2003 F250 reg. cab long bed work truck with the 5.4 v8 and I was getting about 15-17 mpg freeway. When it was totaled, I acquired a 2000 cc sb F250 with a V10 and was getting 16 with more in the bed of the truck and extra weight because of the extra cab and lots more bells and whistles such as the bigger mirrors with convex, carpeting, tonneua (sp) cover and all that stuff. They had the same 3.53 (or therabouts) rear end gear and the same model transmission.

I think it was because the v10 can more easily pull the weight of the heavier trucks, so the engine itself doesn't have to work as hard. Same idea as the 5.4 V8 versus the 4.6 in the F150. This has been my experience between the two trucks. I bought my 03 brand new and the '00 was 7+ years old at the time I bought it in excellent condition.

 

That is a good point.
Engines with turbochargers change the story though.

 

How is that?

 

Are you at all familiar with the ecoboost?

When engines with a turbocharger get worked hard, extra air is forced in, so they are not limited to the power they can make on they're natural volume of air.
With a NA gas engine, the harder you load it down, the more chances that it will start running richer with retarded timing.

I think it's possible to get better economy from a larger engine, but that would not be an every day fact. Looking around these forums, I think you'll find most v10 owners get slightly less than the 5.4, although it's worth it for the extra power.

 

Can you guys help me with something?

If I remember right, on a law mower engine you turn the mix screw in, it leans the motor and rpms go up. But, does power go down? Then you can rich it, slow it down. Is this higher power output but sluggish feel?

I'm leading to some thoughts but I'm not that much of an expert. With drive by wire and engines that won't run without a computer making adjustments in real time, I would think a major re design of the v10 could very well make much better power and be more efficient. Couldn't they lean out 4 of the cylinders, helping the power providers keep spinning at certain times based on a whole lot of other stuff? Seems like lots of options?

I can't even come up with anything to say about the small diesel I wish I could get.

 

The irony in this thread is amazing.

 

I know, really funny.

 

Theres no doubt you could tweak a v10 a ton of ways to get better mileage.
I doubt it would be cheap.



To get the absolute best mileage with any engine in a vehicle....

1. Find the HP you need... and i don't mean peak, I mean how many HP actually getting used down the road.

2. find an engine that will provide that power with the lowest brake specific fuel consumption at the right RPM's.

1 isn't too hard, 2 might have some data available, but I have never found it.

 

Pffft, we all know the 300 is the best engine ever made.

Can't beat that 145 horse.



I'd kill to have a small diesel in my rig. The 4.4L sounds like a tiny little monster!

 

Maybe we will find it in small trucks if GM is intruducing the Duramax 4500 as the rumors tells.

Next month is July..........

 

What parkland said ^

 

I think Ford WILL make a small diesel someday. The Grand Cherokee is getting a small diesel engine in 2013!

 

the new ford transits are going to be avalible with the 4.4L, there also using it in some military vehicles so only a matter of time until it goes in a f150?
