torque
Ok so I have an 83hour f-250 with a 460. It is coupled with a c6 auto 3speed tranny. I know what the motor is rated at out of the crate and I know what the tranny is rated at as well. What I wanna know is if there is some way without dynoing I can find out how much my truck is puttin out at the wheels. Torque and hp. Any help would be appreciated and I know without a dyno it'll just be a give or take estimate. This is just for personal knowledge..........for now. Thanks

If it's a stocker, save yourself time and money and figure maybe 80% of what is published.
Or go to this place:
The Dyno Edge
Don't know where you're at, could be around the corner or it might take you all day to get there.

The engine produces torque. Via the TC and gear reduction, the trans multiplies this torque to make the vehicle move. In the process, some power goes up in heat due to the friction in the trans, axle, u-joint etc.
So the net engine torque to reach the rear wheels is roughly figured at 80% of the flywheel torque figure.

They would be very rough numbers and would only be peak but you could take the truck to a drag strip and run it a few times, take your time, trap speed, plus weight of the truck and plug them into any of the HP calculators available online. Again, these wouldn't be exact but would give you a baseline and something to bench race with.

Think about it. If you lean 250 or even 500 lbs into the back of the vehicle, how fast will it accelerate? The gear reduction multiplies the engine torque to get you moving. Note that's the short version of how it works.
Gears just give the twisting force a longer "lever" against the load.

Bear 45/70....say for example if i were to put it in first gear. And not in 4low first gear just regular first gear. My trucks gear ratio is 2.45:1. Are you telling me that in first gear if I put my foot down that I'm slapping the blacktop with roughly 2000'# of torque?
