I mentioned this in one of my earlier posts. In the "lighter duty" truck packages the weight of the diesels can become a disadvantage in carrying capacity, not due to the limitations of the motor itself but due to the limitations of the platform it's installed in. A combination of any or all of lighter springs, less capable tires, the height of the lift block UNDER the springs, etc. Those are all factors used in the consideration of the trucks load capacity ratings. Obviously those all change between 250, 350, 450, etc and not all configurations are available in every platform.

My contention is that since the claim is "my V10 will out pull your 6.0" any day of the week, and not my total truck package will out pull yours any day of the week, that we should move up into a package that ceases to be the limiting factor and places more of the burden on engine limitations. Bill decided to jump up into the 550s. Perfect.




I don't. It is just a performance comparison. Bill is the one that says "Let her rev out and it will out pull the diesel". The diesel makes it's power at or near normal highway speeds at "normal" rpms for those given speeds. Somewhere in the vicinity of 2500 rpm. The V10 on the other hand makes it's max power right about 4500 rpm which is not normal highway rpm.

Mine will pull just fine on flatland too, at least in the 8-9K trailer weight range, but I don't know kind of hills you're talking about because when I hit them suckers in WV 4500rpm is almost a given, just to sort of maintain speed.

 

That's either a very low quality plug or you live by the sea. But rust has nothing to do with spiting a plug. I've pulled rusted plugs out of all kinds of things from Honda's to Buick's, the actualy retainingpart of the plug is around an 1/8" or more thick and won't give out that easily.

 

Does it have a calculation for the duration of time between a post that says "my X will out pull your X" and a post that says "no it won't"?

 

I have to see if I can beat Bill to 8000 post in this thread

 

How about now?

 

Towing 12k, my V10 kept jumping between 3rd and 4th. 3rd being around 4500rpms, but I could gain speed going up the mountain. I would get to 75 then let the truck kick back to forth for a mile or so untill it got to 65 and kick it back down to 3rd. It would have maintained 60-65 in 4th going up the mountains, but I was in a hurry so tried to keep it in the 70's.

But the truck pulling 12k certainly did 70, it may not have been as easily done as a PSD, but it did it.

On the flat ground, I didn't even break 3000 RPM's except maybe when I was getting on the highway. But it maintained 5th gear without a problem in Ohio.

 

My point is that when two trucks have the same gvwr, the one that weighs less is going to be able to tow more legally. I haven't looked at the numbers, but Bill said both 550's (v10 and 6.0) came with the same gvwr. Assuming he is correct(not saying he is, since I haven't looked up the numbers), the v10 would be able to tow more legally since it has the same gvwr and weighs less.

Yes, both Bill and myself are saying let the v10 rev and it will pull better than the psd side wants to give it credit for. But we are also saying that you don't HAVE to run it that hard to maintain speed, because some people think it can't pull itself up a hill unless it is WOT and 5,000 rpm.

I have pulled trailers all over WV(been to every county but 3) with my 5.4 and the only time I hit 4,500 was when I chose to just for the fun of it. I was pulling ~9k up I-77 going past Bluefield and Princeton. That is a 6-8% grade for about 10 miles. I held it at 4,500 the entire climb, but it normally makes the climb at about 3,500. Some other hills I have pulled(and know the names and know other people on here have pulled them too) that were at least 55 mph are Fancy Gap, Buckner Gap, Sams Gap(all ~8% and a couple of miles long) and Dante mountain (10% for 3 miles). None of them required me to run WOT at 4,500 rpm to maintain speed. There are several local hills around here in the 15-23% range, but they are fairly short and the speed limits are below 45.

 

I think the best point is you CAN ROLL COAL AT THE YUPPIES CAR NEXT TO YOU!!!!!!!!!!! LOL !!!!!!!!!LOLOLOL!!!!!!!!!!!!!!!!!!!!!

 

Nah. My PS never release single puff of smoke when warm. Even on cold start I seldom see any smoke.
Than I remember my motorhome with 300 HP CAT. CATs are famous for smoking and my model was a good one. While towing 5000 lb boat at Lake Tahoe (over 5000' elevation) nobody could make the green light behind me. They just couldn't see it.

 

I could make it with 20,000 just fine. Worst MPGs I could get would be 7 and it could go as high as 10.
Don't forget my fuel is cheaper too.
Exactly. Its that I can't compeat with guys with 3 car haulers when I can only take one car at a time. My engine has nothing to do with it.

Ok, I did the "build your own" on there web site last year and they let me build a 33K cap. V10 F550. Same gross capacity as the 6.4 F550.

I know it can and will.



Thats were 90% of its torque at 1500 RPMs comes in.
You will not pull it as fast as at 4750, but you will still do ok.
I would rather let it sing then lug though.

Hahaha

 

I have been offline for a bit so when I got back on I came in and I knew with a Doubt this Thread was still going when I looked there was still up top LOL

 

Yup... I am already sharping my keyboard to make 10,000 th reply

 

The funniest part of this thread is the gas drivers dont realize that the diesel owners have or have had gas trucks before! I personally have had any make of ford gas engine made. So i know what they can and cant do.

 

Well...can't expect too much from gasoline sniffers.
Did you drive Ford wagon with 1.9cdi engine? I clocked one at 224 kph in Alps -courtesy of French car rental. That is about 140 mph. Didn't care if it made only 30 mpg at this speed. That was 10 years ago. Takes long time for Ford engines to cross the Pond.
