I always found the easiest way to understand is think of a door. Torque is near the hinge (high pressure) and HP is near the edge of the door (Speed) Theres a saying "Torque wins races, HP sells cars"

It's important to keep in mind that torque isn't constant, and neither is horsepower. Just because you've got your pedal to the metal doesn't mean you're getting your full torque. It changes based on your RPMs - it starts out lower at low RPMs, reaches its full value towards higher RPMs, then drops off a little again as you get up towards red line.
If two cars have the same weight and the same torque but different horsepower, then they'll both have the same acceleration at low speeds but the one with higher horsepower will be able to keep that acceleration up into higher speeds. If two cars have the same weight and the same horsepower but different torque, then the one with higher torque will have better starting acceleration but it won't be able to keep up that advantage once you're both at higher speeds.

Torque is a measurement of force. Horsepower is how many times that force is applied. For example, if two engines make equal torque and one makes it's peak torque at 5000 rpm's and the other makes it's peak torque at 7500 rpm's the one that produces the peak torque at 7500 rpm's will make more horsepower because the torque (measured in foot pounds) is produced 50% more times than the slower turning engine.

LOL.... He was converting horsepower from torque, not actually defining what horse power meant. The topics at hand were definitions and not conversions ...... Back at ya !!!

Torque is what snaps your neck back sticks you to the seat and plants a huge grin on your face.

To the OP, everything else held constant, more torque means faster. The Mustang guys, I presume, think of their V6 as a "torque monster" because when it was introduced, it produced quite a bit more torque than most V6's. There had been lots of V6 before it which made similar HP, but relatively few (in this price range) that could match the torque. It makes the Mustang V6 FEEL powerful, because you can feel the grunt. The V6 used in the Camaro makes more torque AND more HP, and from a performance perspective is a superior engine. They're definitely right about the Mustang's lower weight being an advantage.

What ..... Hp= torque x rpm / 5,252. Looks like a conversion to me, try reading the post I was referring to... A unit of power in the U.S. Customary System, equal to 745.7 watts or 33,000 foot-pounds per minute. <------- Definition ..... See the difference ?

Considering that the conversion posted is basically the definition of horsepower and how it relates to torque...

A conversion is not a definition by any means ..... It's like someone asking what Voltage means and you throw up Ohm's Law ..... Still doesn't explain what it means ..... Everything has an actual definition .... And if you can't converse like an adult without all the face palms move on, because I'm not impressed with your keyboard commando behavior ....

Lets take this and put it in perspective for the logically challenged... The OP (and several contributers) have stated a lack of understanding regarding HP and torque. Using basic analogies, posters have provided a basic insight into the BASIC understandings of HP and Torque and the difference between them. The OP then asked how HP and torque related in regards to performance upgrades. Fast forward to: Quote:
Then along come "keyboard commando" SlingShot with the first "LOL OH EM GEE YOU ARE WRONG" post of the thread who proceeds to argue that his Dictionary.com definition is the only acceptable answer to the question, even though it in no way addresses the actual query. How does saying "HP = x ftlbs and is named after Watt" answer anything for the OP, who has expressed a lack of in-depth technical knowledge on the subject. Just for you Captain Dictionary...

And what did you do that was so superior? You told us how to convert horsepower to watts or pound-feet per minute. DG's definition was better than either of your conversions.
