so its not bad, just worthless?


And you think this why?


It was a short hill, and the V10 was running it down in a hurry.
The 6.4 topped out at 50, but the V10 was at 56 IIRC and still gaining speed.

 

Because he had, if I recall correctly, a 2008 5.4.

 

Why would you think it WOULD catch fire?

What in the V10's design would ALLOW it to catch fire? The 4R100 I have might puke tranny fluid all over the place and THAT would catch fire, but then, your 7.3 has the same tranny.

And, by the way, I have run my V10 in 90+ degree heat for over 6 hours quite a few times. That's in the woods, where I was lucky to get it up to 10MPH in 4x4, pulling complete 50-75 foot trees (with tops) for about 1/2 mile, backtracking, getting another one and doing it over and over and over all day long. Never had a heat related issue.

I'd love to put a 12,500lbs trailer behind me and see what it would do up a nice long hill. I'm sure it won't catch fire.

Wanna compare radiator sizes next? (compare sizes, get it?)

 

I've noticed the same thing...

 

Thank you bro!

 

What you are having a hard time with is understanding what tractive force is as well as what we are arguing. The reason the psd wins those shoot outs that the magazines do is because, like Bill said, they are over very short distances. That means that for the majority of the pull the v10 is being compared to the psd in the same gear and at the same rpms, where there is absolutely no comparison between the two(psd wins that hands down by a mile). Make it a longer hill and the v10 will be able to utilize its ability to stay in a lower gear twice as long and the results will be a lot different.

Just for comparisons sake, with both having a 3.73 and TS and going from a 2,000 rpm start in 1st gear, the v10 has a tractive force of 4,763 and the 6.4 is 7,542. By 3,000 rpm the v10 is 5,718 and the 6.4 is 7,097. The 6.4 is already a long distance ahead of it by this point, but it is now shifting to 2nd(and losing tractive force because of gearing) and the v10 hasn't even hit its power band in 1st yet.

What Bill, Tom, myself, Krewat, Sandman and Johnny (to name the ones you mention) are arguing is that the v10 is going to pull harder in 1st from 3,000-5,500 rpm than the 6.4 is going to pull in 2nd, so it is going to start making the ground up and eventually pass it because it will continue to be able to stay one gear lower and produce more tractive force. At normal highway cruising speeds, the v10 doesn't have to deal with getting the load moving from a dead stop or making the ground up it lost off the line, all it has to do is downshift one more gear than the psd and it can climb the hill just as good. You all may think it is screaming up the hill, going to catch fire, shoot a rod through the hood, etc, but all it is doing is utilizing the rpms where it makes the most power.

 

Obviously we exaggerate to annoy the other side, but I have never seen a gas powered vehicle, that would allow holding gas pedal on the floor for 20 minutes climbing the hill at 100F without overheating.
I never drove V10, but in my 7.3 the radiator fan comes on pretty loudly and I know that even in the situation above the fan will come on and off.
Driving 20k set on flat I never have the fan coming on at 65mph.
The fan takes few HP, so my goal is always maintain the speed that will keep it off.

 

How can that be? You mean your bashing something you've never even tried? Wow, isn't there a term for that? I think it's called, "Talking out your something-or-other"

 

Hey! I do that too from time to time. Especially when I eat late at night at Taco Bell. Apparently, the beef does not agree with me.

 

I have made an 8 mile pull on an 8% grade at 60 mph with over 10k lbs on my 5.4 with it being held at peak hp and it never bothered it the least bit. It wasn't 100 degrees, but in the low 90's. I haven't ran into any hills that would require me to hold it to the floor for 20 minutes though. That would be a constant 8% grade for 20 miles straight at 60 mph. Or from sea level to 2,000' below Vail Pass in 20 miles. I dare say the egt's would get pretty high on a psd making that kind of pull long before my gasser would overheat.

 

What Bill, Tom, myself, Krewat, Sandman and Johnny (to name the ones you mention) are arguing is that the v10 is going to pull harder in 1st from 3,000-5,500 rpm than the 6.4 is going to pull in 2nd. (Forgot to quote, but it was by phillips)

What? Does the PSD quit pulling when it hits 2nd gear?

 

Especially on a 10 mile grade going from 5000 to 11000 feet. I ALWAYS (zero exceptions) see the V10's transiting the State in the truck lane with their flashers on unless they are EMPTY. That's why the PSD is the "Big DAWG" when it comes to towing.

 

Yes it does. That is the thing I hate about mine... pulls anything I want to, but will only run 15mph. You think Ford could have designed a better tranny than the pathetic Torqueshift.

 

I'd try something like that with a 5.4....as long as I KNEW I had a truck in reserve to finish the job, like your PSD....

 

No, the psd does not "quit" pulling when it hits 2nd gear, but the simple fact is that when it hits 2nd gear it loses gearing(and tractive force) and does not pull nearly as good as it did in 1st gear. So when the psd hits 2nd gear the v10 is just hitting its powerband in 1st gear. When the v10 shifts to 2nd it will only drop to about 3k rpm, so it doesn't have to deal with the idle-3,000 rpms that it severely lagged behind the psd off the line. From 3,250 to 5,200 rpms the v10 makes more hp than the psd does from 2,000 to 3,000 rpms. For example, the v10 makes 283 hp at 3,250 rpm and 362 hp at 5,200 rpms while the 6.4 makes 247 hp at 2,000 rpm and 350 hp at 3,000 rpm. If the 6.4 shifts and drops to 2,000 rpms and the v10 shifts and drops to 3,250 rpms the 6.4 is going to be almost 40 hp behind it. So each time the 6.4 shifts, not only is it a gear behind it, but it is making less hp too(with a much more narrow power band too, so quicker shifting).

That is your opinion and you are entitled to it, but I couldn't disagree more. But if my 5.4 ever lets me down on a hill like that I will be the first one to come on here and post about it.
