Ok so, for offroading, is torque better than HP?
Im asking because I dont know.
How about desert highspeed running?

It's good for pullin' jeeps and chevies out of the sand.

Both horsepower and torque influence acceleration. Horsepower affects acceleration at high speeds, whereas torque aids acceleration from a stopping point. Because of this, torque is known as low-end power. Since off-road driving (USUALLY) isn't performed at the high speeds of highway driving, low-end power is crucial in pushing your vehicle through the many slow-downs and speed-ups you encounter at ditches, debris-ridden paths, bumpy terrain, and muddy or snowy roads.

That said, you'll have more of one when you have more of the other. And you want both. As much of both as possible! :thumbsup:

Is there any way to delet my post?

Thanks for answer, Dan and xjr

What you really want are two flat power curves. Torque is the engines ability to spin the wheels, the twisting power. Horsepower is how fast it can spin the wheels. Without torque, you cant move and without hp you cant go very far. Luckily, when one goes up so does the other normally. Because trucks are heay, and they dont need to go that fast (relative to cars) they have engines tuned for low end torque and flat power curves, at the expense of peak numbers.



I think.

Here is a link that will explain it all in great detail.

It's a long read but worth it.

I shoulda studied harder when I was in school...
