Passed 2 ford diesel on a 7 percent grade
I was coming home from desert trip back into San Diego. I was passed by a couple of diesel truck on the flat before the grade. They pulled ahead and out my sight. I guess they where doing 70. Going up the grade I found the 6.0 and the 6.4 pulling the grade, Dam they where going slower then me. So after waiting for a car to get out of the left lane, I pulled into the passing lane gave her the pedal. Went from below 50 to 60 mph and passed them on the step part of the hill. I check their badges as I passed them, they gave me a look over also as I was passing. They were giving the trucks all they had. The size of our trailers looked about the same, so I GUESS the loads were about the same. They both passed me again when the grade leveled out on top. I try to keep to about 60 mph when pulling. The V10 has no trouble pulling the grades. I do admit to using more gallons of fuel then the diesel trucks. I do love the diesel, and in 5 years I might even buy one if they can prove to be as reliable as my V10. My 6.0 has really soured me to the reliability of the current diesel.

I understand that horsepower is the rate energy inputs/outputs into a system. You have to have tq and rpm or some liner movement before you can have horsepower. So to measure it you calculate. Now if your ask what you use to measure horsepower than that different but not what you asked. I answered what you asked.
Kajtek was making suggestions of converting back and forth between sae and metric. My answer is simply its stupid cause we american have a system and for us to us metric would be a mixing of the 2. Instead of going and getting a gal of gas you'd be getting 3.8ls. If tried using liters. The 3 liter around here anyway didn't do to good. I understand that metric system isn't using ozs to make its liters. I was saying just what I mean. To convert you would have to re teach a whole country how to measure stuff. How to rethink. Seems much easier to just know how to convert. Which I can show you i know how to do.
Oh my BlackBerry has a spell check. Sometimes I forget to check to make sure its still checking. I can't spell worth a flip. You replied so you understood me and that's all I care about.

That's my point, kinda. You didn't go that extra step. In order to know horsepower, you have to know torque and rpm, true. In order to know torque, you have to use some kind of measuring device, a dynamometer. Now there are engine dynos (flywheel) and there are chassis dynos (wheels) and then within each type of dyno there are different makes and models, forms and processes, to determine the output. Eddy current, hydraulic, water break, etc. to name a few. Take the same vehicle and dyno it on each of the different types of dynos and you will get different results. Take the same vehicle and the same dyno in different locations (altitude, temp), and you will get different results. Take different vehicles, and... well, you should get the point. Now most modern dynos do compensate for environmental effects with their own or user entered fudge factors, but that is what it is.
My original statement was:
"
It's not made up... it's just a calculation to support the measurement of power. And since there are several different versions of how to calculate horsepower, its meaning and or value has been significantly reduced over the years. Mostly, the only thing horsepower is good for these days is bragging about something that is not understood.
So depending on which equation you use (rounding errors) and which means you use to determine torque, the actual measured/calculated horsepower is just a magic number. Ford says my truck is rated at 350hp and 650ft-lbs. So if I dyno my truck and don't get those numbers, what good is telling me them in the first place?

I'm not argueing your orginal statement. To be honest it got by me. I answered your question. How do you measure hp? If had asked what do you use to measure I would answered with some sort of dyno. I'm a believer in tq. I understand hp is a rateing. My problem is I'm not smart enough to explain it. I'm just lucky to understand it.
Don't sweat it, if anyone one of us was actually as smart as we think we are, we wouldn't be posting here everyday. We'd be like CSI or finding a cure for athlete's feet or something.

lol...They were just lugging up the hill...So because you had a trailer filled with with styrofoam peanuts, you assumed it to be the same density as the iron ore they were carrying in theirs? Yes, I realize you said you "GUESS" they loads were the same, but that is a really uninformed way of guessing how much something weighs. I sincerely doubt they were giving their trucks "all they had", either; unless they had 15k+ behind them. What "grade" are you talking about anyhow? Mountain Springs Pass through Devil's Canyon?
But all those light trailers pulled with gassers had to stop at Frazier Park for fueling, while I pass that stop and have never seen them again

.Actually, I think in an unloaded match a golf cart could probably beat me, but I didn't buy my truck to be the fastest up the hill. I bought it so I could always get up the hill.
My strategy is to wait until the 6.0 breaks, the 6.4 clogs it's DPF and the 6.8 has to stop for fuel. That's when I pass all of you in my 7.3!

The 6.8 gasser is by far the better cold weather motor.
I've owned 7.3's and a 6.0. Neither was as reliable in the cold.
In Saskatchewan cold means below -35. If I am working somewhere all day I do not have to run the truck if I can't plug it in. The gasser always starts.
And fuel does not gel. Gasser wins for cold temps. But then its really not disputed by those who run in the cold.

why cant you just give the gasser some credit? if im hauling a midsize car on my trailer and their hauling a different brand midsize car im gunna GUESS their around the same weight. if they were hauling steel and he was hauling "packing peanuts" then he would not say there around the same weight.
