You people are such ****ing idiots, you just have absolutely no idea what torque and hp really mean and how they work to accelerate a car! :rotfl:

You too then can explain how the S2000 finishes the 1/4 mile 3 seconds faster than the TDi yet, according to you, doesn't push you back in the seat as much. When you come up with the answer, please let NASA and the US Air Force know. I'm sure they would LOVE to learn of this secret technology that Honda has come up with that allows the S2000 to violate the laws of physics.

Don't bother replying to this message until you have a satisfactory answer to my challenge above. Not replying shows you are an idiot. Replying without answering the challenge shows you are an idiot. Ready? GO! :wavey:

4.10's are the taller gear? Usually people consider low gear ratios tall gears.

if you are asking the difference between HP & TQ, you are about to open up a big debate if the right people see it. but here's a very general way that it was described to me. TQ is what makes you move, HP is what makes you move fast. i'll give you a opposite for instance of mogs...........

if you see a semi going up a steep hill & he's going really, really slow. well at some point the truck would stop if he didn't have enough TQ to pull his weight. but a diesel engine produces high abounts of TQ, but not high amounts of hp, that's wht they never stop going up a hill, but they will go slow.

No idea what the question is but a s2000 probably has a higher gear ratio, that will allow it to use its RPM band more efficiently. The motor probably produces its torque higher in the RPM band and with the taller gears multiplied to the torque out puts of the motor, it probably makes more torque than the other car at the tires which equals acceleration. When you produce your torque higher in your RPM band, it allows you to use a taller gear ratio. LIke a 4.10 compared to a 3.27. The 4.10 is considered a taller gear.

Or it is because that car is lighter than the other one.

There are a couple of good articles on accelleration on the front page of www.modulardepot.com. Take a look at those and see if they help.

torque is what gets you down the track, hp is what you brag to your unknowing friends about.

HP is how fast you hit the wall. TQ is how far you move the wall.

The reason diesel engines are so torquey and usually have lower HP numbers is because of their redline.

My friend's 7.3l f-250 redlines at like 3k RPM.

Since HP = (torque * RPM)/5252

HP is dependant on torque and RPM's.

Lets say the 177lb/ft TDi redlines at 5000RPM (if max TQ were at redline)

and the 164lb/ft s2000 redlines at 9000RPM (if max TQ were at redline)

(177 * 5000)/5252 = 169 hp
(164 * 9000)/5252 = 281 hp

BUT

s2k w/ 5k RPM RL
(164 * 5000)/5252 = 156 hp

Although the TDi created more "power" at a given RPM, the s2000 can handle a lot more revs which, as mogs stated, allows for much better gearing and therefore more acceleration.

Just read the articles on MD, like stated before. [/thread]

Here's a great quote from one of their sigs:

"Horsepower is how fast you hit a wall, Torque is how far you take the wall with you"
