why is it that pickup trucks have 325 plus or minus hp but say a ford 750 or an international 4900 that has a gvw rating of 33,000 lbs. only has 210, 230, 250 hp. then to top it off you could even put a 20 ton trailer behind it. what gives? the rear ratio? The 750 and 4900 have a rear with about a 5:60 plus or minus, why not have more hp a granny gear or 2 in the trans and up the rear to a 4:10 or something. Yeah Yeah I know the engineers have it all worked out, but dummy me I just don't see whats goin on.

JoeBob said it best- Horsepower don't mean much other than dealer hype. Torque is what moves you. It's kinda the same thing with the new cars. Little V6 motors advertised with 250-300 HP. Right. Maybe at 7000 rpm, but not useable when you drive it. My old 5.0 Mustang was rated at 225 HP, but it would walk all over one of these 300 HP mini-vans, and they probably weigh about the same. It's all about torque.

not many if any 325hp p-u motors can start a load idling that weighs 50,000 lbs now can they . The small diesels have tons of torque in those trucks

The Ford 750 or the IH 4900 loaded to the same GVW as the 325HP pickup. Will be by comparison a gutless slug when the light turns green or on hills.

Back in 1950 and earlier, the equivalent size of a F-600 would have about 100 HP. Some big trucks in the early 1930's used Model A Ford engines, 30 HP.

tuggle said: (quoted from post at 06:09:13 11/14/07) Same reason why our old tractors like the Ford 8N or JD B has around 15 to 20 horse and todays lawn mowers has around 25 horse. No way those lawn mowers can pull what those old tractors did/do.


That is also flywheel hp to PTO hp, I have always wondered what power the old machines lost thru the driveline. I would guess quite abit.

HP these days is figured in net not actual engine brake HP. Say your furd pickup has a 300 HP rating but the pickup is rated at 9200 GVW. If you put that same engine in a 35000 GVW truck your net HP is going to be much lower because more power is eaten up with the increased wieght and heavyier drivetrain components.

It is also a sale thing . Just stop and think about it for a min. Lets just say that your looking at a pickup and the MFg told ya that it had 125 Hp but made 400 ft.lbs of torque at lets say 1500 rpm the first thing most people will look at is the Hp. and say is that all that it has ??? everybody wants a diesel pick up but just how many really know how to get the most out of one or how to even run a diesel . Jump in fire it up and stuff into gear and out the drive as hard as she will go , pull into a parking lot and shut it down . No warm up no cool down and wonder why there having problems with seals going out of the turbo or even having heads cracking . Or when pulling trailers not watchen the tack and lugging the engine down past the peak torque range of the engine . Then the next thing is that Oh my new truck does not have enough POWER and i need to put a chip in it , well did ya order it to do the job that you wanted it to do or did ya just rush into a dealers lot and buy the one that had the wright color and the heated leather seats and was meant to be a blacktop crusier and not a WORK truck . Todays sales people do not have a clue as what ya need to do to make a give truck do a give operation they just want your bucks . Do you have any idea of what ya need to drag a trailer to make life easier on the truck??

Its all about how fast you want to get things done. 325 hp gets a fixed amount of weight moving in the same amount of time, but a pickup doesn't have the gearing or torque to tackle really heavy weights. The real truck has all this to move really heavy loads but it does it really slow.

Put the 25HP garden tractor on a pto generator or a bush hog/flail mower etc. It will make the Ford8N or B look sick. HP is HP. Tractor weight, weight distribution, tire size/tread affect the max lbs pull. The 25HP garden tractor on a clay track or similar where traction is not limited. It will perform more work than the 8N or the B on the drawbar too.

You can't look at horsepower without looking at what rpm the hp is at. Also the same goes for the max torque is. On most pickups, the max torque and rpm are in a range you will never see in normal operation.

All about the torque and ratios. I have an '85 White/Volvo tractor with a Big Cam 3 Cummins set to 350 horse which is close to all three modern pickup diesel engine horse ratings but I also have 855 cubic inches compared to about 400 cubes. Remember, there is no replacement for displacement. The torque of the pickup engines is say 650 ft/lbs but the 855 Cummins is 1200 ft/lbs if I remember correctly. I have 9 speeds and pickups have 6 speeds. Translation, they pull a full load of about 25k... I weigh more than that empty!

its all in the torque of the engine.
