Not if the sun is in your eyes... Anyway, there's NO WAY a V10 will accelerate from 50-60 and pass a 6.4 that is giving it everything it had. Not going to happen. Period. Unless the 6.4 has twice the load, and half that load were to equal 10,000lbs...However, the OP did state that by looking at it, he guessed they were the same weight. That's real scientific...

Exactly.
Rhetorical question: If I measure two variables and combine them with a mathematical formula to come up with a single value, does that make the result an "unmeasurable" value, ala Horsepower?
Does that mean "momentum" is unmeasurable because it's a combination of mass (torque) and velocity (RPM)?
Nope. Hitting a brick wall with a certain amount of "momentum" is sure to break my skull. The faster I hit it, or the heavier my skull, the more "momentum" is experienced.
This is like "how many angels can fit on the head of a pin?"

Is'nt the velocity and momentum the same thing? Isnt the engine's momentum the rpms?
Would saying hp is a measure of work that has been done wrong? I ask this because you have to have tq and rpms to have hp.

Looked at the ford website for trucks.
F350 DRW, 4x4, 6.7, TS, extended cab with the 5th wheel prep package comes to 41,930. Might put the order in soon. Still waiting on the business to get started before I buy the truck. (thats on Jan 1, but might buy before then)

Virginia Concrete Products.
I had worked with my grandfather in his concrete statue business for years (since I was 5 really). I decided that is what I want to do with my life, so thats what I am starting. Got a 50% share when He sold out late last year, and I still got 750K left to work with, So I figure that I will either get a couple of F350's or a 750. Don't quite know yet. I am still looking for what exactly I need. (grandad used the 3500HD thats in my sig.).

Is this the source of the dyno's you mentioned? If so, what they tell in the article is at best worthless. They don't show the torque/horsepower curves, so any other information is of little value. However, they didn't even as much as state peak numbers, which would also have been worthless since they admit that the dyno for the gas truck was misleading since it stopped below peak hp. Wouldn't the gas truck hit the speed limiter in 4th gear?
The whole article has a very subjective feel, with very little objective data to support their conclusions. If they were confident in the accuracy of their tests, they should have published the data like other magazines do. The mpg claims for the diesel also look very suspicious, considering that the 6.4 has a reputation for getting worse mileage than the 7.3 or 6.0 due to regen. All in all, it looks like they could have written their conclusions before they set foot in either truck.

This doesn't even consider the fact that no one on here would pull a 12 mile long pass at 40mph and 5k rpms. So basically pushing every component of the truck to the max for 20 minutes.
I get the theory, the problem is, there has not been one test posted on this thread that has shown any v10 outpulling a psd (except for the 7.3 that ended up smoking. )

That's the whole problem, v10 guys say they just drop down the gear and run at 5k and it will outpull the psd. However this is the second test where it would not get that high. The first one was the pulloff by dudes on here where the v10 wouldn't get over 3k rpms.

Hey Bill take your camera outside and rev your truck to 5000 rpms for 20 minutes so we can really see it happen.

p=mv (where p=momentum, m=mass, v=velocity)
Let's use this for an example of momentum:
I have a 7000lbs truck - my Superduty. I drive it at 50MPH and hit a brick wall. I impart a certain amount of energy to the brick wall. 350000 is the momentum in terms of MPH/lbs (I think, but that's not the point).
If I drive my 3500lbs Cougar at 100MPH, I impart the same amount of momentum into the brick wall. 350000.
Momentum is much like Horsepower. Same concept. Velocity is RPM, Mass is Torque. I can have half the torque, but spin it twice as fast, and I can accomplish the same thing.
You have to swing a 2lbs hammer twice as hard to make it do the work of a 4lbs hammer.

24 hours of pulling 11,000 lbs around a race track at WOT...with a twin-turbo gas V6 at 90 MPH! Shows turbos glowing red during the test, and the engine took it just fine.
This little V6 is just over half the size of the V10 and puts out MORE power, so the specific power is MUCH higher than the V10. If the little v6 can do it, why not the V10?

Tough to compare that package with a 360-HP 3V truck with the same 5R110 your PSD has and 4.30 gears. There would be a HUGE difference. Shame we couldn't get a truck like that out there for that comparison!
