Malaki i'm curious as to what you make for doing that. I only ran gp out there a couple times when my dispatcher couldnt find anything else but i saw a Lot of o/o's there and i figured the loads must pay through the roof because those loads will flat out tear up a truck. My 387 cried getting in and out of there and there were a lot of supertrucks there with insane horsepower. I'd think to get a guy with lots of experience to do those regularly as company or o/o they'd have to pay you incredible money.

It's not the horsepower that gets the trucks moving, it's the torque. Horsepower is just simply to maintain speed. The reason why the higher horsepower engines seem to be more powerful isn't cause of the horsepower but the increase of torque. Example:
475 horses produces about 1875 ft/lb of torque at 600 horses produces about 2200 ft/lb of torque. I don't remember if those are the exact numbers but it's just an example anyway. BUT that is just half the equation though. There are so many different rear end gearings and transmission set ups. You can take two identical trucks with the same horsepower rating and torque rating but have a different tranny and rear end and one truck may run it's rear off but the other truck will struggle.

I haul into the GP, not out. I get paid percentage, and I think the load pays me something like $175 for the 6 hour run down there. We always deadhead to Richmond for a return load.
As for the truck/power, I drive a 2002 Volvo 780 with a 450hp ISX and 10spd autoshift. I have no trouble on the drive down there. Of course, a few of the hills really slow me down, but that comes with driving in WV. As for the route I take down, the only trucks you see on it are the local log trucks and coal trucks. I guarantee no company will route you the way we run through WV.

Some great advice and some that's just silly. The whole post seems a little bi-polar though.

CALM DOWN and be positive. vs You very well find you messed with the wrong guy and that he follows you to your next stop and beats you to a pulp. You think fistfights scare a guy who just pulled 80,000 pounds down a 7% grade on ice?

You can take two identical trucks with the same horsepower rating and torque rating but have a different tranny and rear end and one truck may run it's rear off but the other truck will struggle. It's not torque that moves a truck, it's horsepower. NOT peak horsepower, but horsepower none the less! Torque is a number you measure. Horsepower is a CALCULATED figure derived from the TORQUE measured at the flywheel, or at the wheels most of the time. ANY time you have torque moving at ANY RPM, you have horsepower. HP = (torque x RPM)/5252. Period. You could have all the torque in the world, but if there is NO rotation, or movement, you have 0 horsepower, and 0 movement. I could stand on a pipe on the end of a wrench, and have just as much torque as one of our heavy diesels puts out. Does that mean I have the power to get a truck moving? Not quite. Say your truck produces 100 lb-ft of torque at a 600 rpm idle. Our formula for HP would mean that you are putting out 114 HP. THIS is what is getting your truck moving. That motor at idle is pulling JUST AS HARD as a little 1.8L honda civic motor is, when it's at peak horsepower. Yes, that's right, if you could gear a honda civic motor to put out it's peak horsepower, somewhere around 6,000 rpms, at a road speed of 1-2 MPH, that little motor would launch your truck just as fast. All this at 100 lb-ft of torque...but a MUCH HIGHER RPM. So, if you have a motor, want to give it more HP, all you have to do is increase the RPMs where the PEAK TORQUE is, to make that same amount of torque work harder, because it's spinning faster. If you take a detroit diesel series 60, push it's 1650 lb-ft of torque to 2,000 rpm, you would have 628 HP, with that "little" 1650 lb-ft of torque! end of rant....flame away!!! :lol:

Here's my opinion on all this,4wheelers,motorcycles,18wheelers etc.
Do they move by their selves?No they don't,who operate these vehicles? Riiiiiiight,WE do (humang beings). We all have different habits bad or good,emotions,bad days,good days etc.So in my book there's no blame on "truckers or 4wheelers". We're all in it together,just this afternoon an 18wheeler was right on my bumper I was going 65 mph and we're in the middle of Houston Tx we were in a turning lane and of course I had someone in front of me but I had sense enough to leave some space in front. I believe keeping space is the best thing you could do to keep yourself out of trouble,4 or 18 wheels. PS if you're worried about a 4wheeler slamming on his brakes aren't you too close?
