My horse has never had problems with its turbo.

And glow plugs? Kinda like spark plugs, right?

I've changed my glow plugs once, and it was only about 10,000 miles ago.

What else ya got?

 

well, you have a 7.3 so i cant say much.
They are great motors.
when My dad bought this truck, It took us 6 weeks to decide if we wanted the 7.3 or V10.
We went with the V10 and have always been happy we did, but If I had gotten the 7.3, I am sure I would love it to. It would just need mods to be as fast as a stock V10...

 

Others beat me to it. Lower RPM, better fuel economy, less noise, less wear. The same reason a stock 7.3 might be more comfortable to tow with than a V10, even though the V10 should pull more.

It's all about the gears. It's possible. But if it were practical and desirable, they would be doing it, and they're not.

...and slow WAY down on the hills, because their horsepower to weight ratio is vastly disproportionate to our pickup trucks. That 400-ish HP is enough to overcome rolling resistance and wind resistance, and small hills, and keep them rolling at freeway speeds. But as soon as they come to a serious incline, they have to slow way down and drop gears. 400 HP will only do "so much" work. On a hill, the work changes from a low-drag/high speed situation to a high drag/low speed situation. And since power = force x speed, power is ultimately the limiting factor.

It does not. You can NEVER have more horsepower at the rear wheels than you have at the engine. That is physically impossible.

Heh heh....

 

I think somebody actually needs to look up the definition of WORK. Force applied across a distance. W = F x d . For a given distance (d) the C9 can apply more force (F) which will ALWAYS equal more WORK (W).

Edit to add. I misread the post earlier. I READ Cat C9 but had in my head "D9". I thought we were arguing the ability of the V10 to out work a D9 dozer. DOH!!

 

Well, now that you mention it, of course a V-10 superduty can outwork a d-9.

With a blade added to it, and of course the proper gearing, it's a catskinner's dream, it'll work circles around a puny D-9.

 

You're leaving out time. A higher horsepower engine will do the same work faster.

 

i think you misread what he was asking. he wasnt saying you can have triple the hp at the wheels as you do at the engine. he was saying that the torque on big rigs is usually 3 times higher than the hp(400 hp and 1200 tq). the answer to that is because they are pretty much all goverened around 2200 rpm.

 

I guess whiner wasn't the right word. He brays louder. He's perfectly happy eating the scraps left over after they make Bill's food. Unfortunately they don't have a lot of scraps left over and the demand for the scraps is very high. People even heat their homes in the northeast with the scraps so Krewats food bill does sometimes exceed Bills. Luckily, Krewat doesn't eat as much. Bill has to stop and eat just about every time he passes food.

 

yeah I left out time there, but I was still thinking about a dozer. I had in my head that if you couldn't even apply enough force to move the object (like a huge load of rocks) that you couldn't actually perform any work, and time would be irrelevant.

In all reality power and work are not that simple. Horsepower is a product of torque and rpm/5252. so torque comes into play as well. You are correct that given the same torque, a higher horsepower engine will do more work for a given time.

It isn't just about horsepower though.

Also since we're talking about work and time I thought I'd add the following. I believe the lower RPM's the diesel operates at, yields itself to a longer lifetime of work. Meaning, that I think a lifetime of work at 2500 rpms would be less stressful on a diesel than a lifetime of work at 4500 rpms. I know that there are some high mileage v10s out there, but I truly believe them to be the exceptions and not the rule. I'm not stating that as a fact, just my honest opinion.

I seriously considered buying one at first, but I spoke to numerous contractors working for the same company(ies) I do work with, and they all complained about fuel mileage. None of them got more than 10 mpg when towing or with a loaded truckbed. Seeing that I'm usually towing (3500-7500lbs) daily, I was turned off by the fuel mileage. That was before I found FTE though, and I had no prior knowledge of either engine. I chose the diesel for the simple fact that 9 out of 10 work trucks I saw were diesel, with the overwhelming majority being Fords.

I'm happy with my choice, and I enjoy the fact that I can be towing 12k at 2500rpm +/- with OD off, and still have plenty of pedal left to pass the occasional (more like frequent) gray hairs on the road. One thing that did strike me as interesting is when I was searching for my truck (2005), I couldn't even find a used one with less than 100k for under 30,000. NO WHERE. I know 100k isn't alot of miles, for this engine, but at that time I wanted one with some warranty left. I ended up finding mine with 54k, and talked them down to 25,000. There were plenty of v10's for sale at that time, and most were about 5,000 less. The higer resale price was an added bonus, even though I plan on keeping this truck forever.

 

i know how we can settle this once and for all..... i have an international big rig wrecker that has a cummins 8.3 with 400 hp and 1250 tq. we can hook a v10 with 400 hp to it and have a pull off. ill start out in the appropriate gear so that our final drive ratio will be the same. heck, ill even put it in neutral and let you pull me in 1st gear until you get to 3k rpm before i get on it. youll have a rolling start, gearing advantage AND be in your prime power band before i even let the clutch out. any takers? im sure it will make one heck of a video

 

So what is the verdict. After all of the education we have received regarding HP and Torque. Which truck is the better truck.

Wow, that is a loaded question, huh?

I think both truck/engine combos are good. It all depends on personal preference. I think the V10 in STOCK form has better performance. But once the PSD is SETUP, the V10 doesn't stand a chance.

 

I do not have to gas up that much.... I can go over 300 miles on my 36 gallon tank.

 

ROFL. You are so funny. I like simple stories.

 

You are too funny man.

I still would rather have a clydesdale than a quarter horse.

Personal preference I suppose.

I have squeezed about 600 miles out of a single tank.

Consider also that I usually stop at about 1/4 tank for fillups to avoid running out of fuel. I also have a lift, and performance mods.

 

youve been driving that 460 too long if you think thats good gas mileage lol. by my calculations that is only 8.3 mpg. 300/36=8.33. with my old 7.3 i can go 800 miles on a 40 gallon tank. granted, it does get a lot better mileage than the 6.0 and 6.4. but this is v10 vs psd, not v10 vs 6.0 and 6.4.
