You call it chaos because I disagree with you, and you dislike having anyone disagree with you. Nope; little johnny acts like a little kid when someone disagrees with him. You're a RABID defender of the V10, and it shows. This entire thread has been chaos from day 2, and that's why Krewat keeps it confined to here. He does it because of people like YOU, and to a lesser extent, me. I post on many other threads, and it remains civil. It's you, sand man, and a couple of others who try to devolve this thread.

 

You have to start watching what you say. More below.

Don't pretend you have any inkling of why I do what I do. And as for devolving the thread, I suggest you go back and read it without the names on the posts. It's interesting to see who does what.

And you have not remained civil on other threads about this subject, where I've had to delete your posts in them.

As for accuracy, for the record, I have not seen one single post about anyone saying the V10 can hang with your PSD over Vail's pass at least in the higher elevations. They HAVE said they won't break down doing it, but you ignore that part and continue to say the V10'ers brag they can do Vail's Pass but don't offer to try. And other inaccuracies abound in your posts, but let's just ignore those, right?

I respectfully suggest you take a day or two off of this thread, and at the end of that time, if you care to participate further, let's not post about how "little johnny acts like a little kid when someone disagrees with him", and all the other mildly insulting comments. From ANYONE.

 

On a different note, I sold my truck. lol

Actually I sold my whole truck and horse trailer combo. Apparently someone getting into the horse biz with some money wanted it for their kids horse. Hope my kid realizes I won't spend $62k at the drop of a hat for a hobby of hers, but whatever.

So now I'm going to set tight for a few months and buy a smaller horse trailer, probably in the 7k lb range. Then I'll debate between a F350 SD with the 6.2 or a F150 with that new Ecoboost. Not a big fan of a V6 truck, but the ability to tow my future trailer and get around 24 mpg highway (empty) is an appealing thought.

 

Here is a different way of looking at the numbers. for anybody that cares.....

All measurements from advertised power numbers, in PER LITER of displacement.

C15 (14.7L I6 ) CAT @ 435hp / 1850tq

125 lb/ft
29.59 hp

6.7L V8 PSD @ 400hp/800tq

59.7 hp
119.4 tq


6.0L V8 PSD @ 325hp/570tq

54.16 hp
95.0 tq

6.4L V8 PSD @ 350hp/650tq

54.68 hp
101.56 tq

7.3L V8 PSD @ 250hp/525tq

34.25 hp
71.91 tq

6.8L 2v V10 Gas @ 305hp/420tq

44.85 hp
61.76 tq

6.8L 3v V10 GAS @ 362hp/457tq

53.23 hp
67.21 tq

5.4L 3V V8 Gas @ 300hp/320 tq

55.56 hp
59.25 tq


Lets chew on this for a while.

Interesting to note that the two engines known for longevity, the CAT and the 7.3, both have VERY similar hp per liter ratings........

 

Weird how no v10 guys have commented on the pickuptrucks article... I mean, the 6.2 and 6.7 have the exact same hp, and you got your transmission and 4.30 gears versus 3.55 on the psd, and you got stomped on both pulling test.
I thought all that mattered was horsepower so they should have been dead even, right?

 

The 6.2 has less power than the 6.7.

All that matters is HP. Becuase of having so much more low end torque the 6.7 has much more at low RPM. There is no RPM where the 6.2 makes as much but the gap is much, much wider at low RPMs.

If they both hit the hill at speed already then the diffrence would still be there, just smaller.

 

Look at the quarter mile time with a 10k loaded trailer here:
2010 HD Quarter-Mile Acceleration Test (Loaded) - PickupTrucks.com Special Reports

The 6.2 gasser did it in 23.3 while the 6.7 diesel did it 22.3. So for $7k you got to knock 1 second off the ETA...

Empty truck here:
2010 HD Quarter-Mile Acceleration Test (Unloaded) - PickupTrucks.com Special Reports

6.2 did it in 17.5 while the 6.7 finished in 17.1. And that assumes you spool up the turbos before you take off.

So what's all that torque doing? I mean the 6.7 has twice the torque right, so it should be able to smash the gas engine... I bet for the $7k you save getting the 6.2, you could easily make up that 0.4 second difference.

 

When was the last time you drag raced with a trailer. We have been talking about pulling hills. Though I would rather see how they perform on a 6 mile grade with a running start than 1,600 feet.

 

Doesn't make a whole lot of sense, comparing horsepower/ft-lbs per liter, because most/all of those diesels are turbo'd. If you measured per cubic-foot of air, that might make more sense.

 

You may have missed this in the prior posts so I will say it again, it is not theory when I run my 5.4 against my 7.3 and it beats it from a dead stop, from a rolling start and from a 55 mph start. The math says my 5.4 will beat it and my speedometer proves it. That is fact and as real of a test as there can be.

 

Ya, and what, a 1997 psd against a 2005 5.4? Either way you said the math says a 2008 v10 will outpull a 2008 6.4 because of the 12 hp advantage...

 

No, it's a 2000 2v 5.4 against a 1997 7.3. Both have 4.10 gears, the same tranny and weigh the same. It doesn't get any closer than that for a fair comparison. The 7.3 has more tq and the 5.4 has more hp and the 5.4 wins when I compare them.

The reason the 3v v10 wins isn't because it has more peak hp. Peak hp doesn't mean crap(look at the hemi, no low end power at all). It's because it has more hp all across it's power band than the 6.4. At 3,250 rpm it has 280 hp and at 5,200 it has 362 hp. By comparison the 6.4 has 247 hp at 2,000 rpm and 350 hp at 3,000 rpm. The 6.4 will do better off the line if both are geared the same because it has more low end hp. No one is denying that. That is why we are saying the v10 needs the gearing to get the load moving and get it in its powerband if you are comparing them from a dead stop.

If you run them from a rolling start with both at peak tq doing the same speed the v10 is starting with 280 hp and the 6.4 is starting with 247 hp. The v10 would fare a lot better in that kind of test(like cruising down the interstate and downshifting to climb a hill, i.e. real world driving) than it would the 700 foot long shoot outs that favor a diesel.

 

At least you didn't say he was lying this time lol. I agree that a diesel(turbo) is better at your altitude. At least as far as pulling power goes. I have no doubt you would out pull a v10 up vail pass however you want to compare them-rolling start, dead stop, etc. I just don't buy the part about them having their flashers on and doing 25-35 mph unless the driver is one of those that is afraid to run it over 3,000 rpm.

 

I like how in Colorado, the trucks are the most powerful, the hills are the steepest and evidently the egos are more fragile. But here on the west coast, at least I can read. Not once did I ever say my V10 would outpull a diesel. Not once. Yet I see my name mentioned time and time again by a few diesel owners as being a "V10 or nothing" kinda guy. Not true. Not even close. Look, if you and your imaginary 16 year old son are all warm and fuzzy about your truck, dandy, after all, you're the one who's paying for it, right? I'm sure cabin fever can be rough, but at least try to get out and get some fresh air once in a while.

 

torques usually a good estimate for pullin an hp for speed. do you need a fast truck or a strong truck? my old diesels a brick but she pulls hard... hop in the car for speed...
