OK, I understand what torque and horsepower are from a definition standpoint. But, I don't understand what people mean when they say that the S2000 does not have enough torque. By this, do they mean that at low RPM the rate of change of the RPM's is too slow? I'm just trying to understand how you "feel" torque. I'm not trying to get in to one of those HP vs. torque debates.

 

I can't give you mathmatical equations either, but what you may need to do is get into a Corvette or some other American Muscle car and let someone slam on the gas from a stand still. When you get pinned to the back of your seat from the "pull" of the car, that's what people talk about when they say "torque".

 

your pathfinder, i'm assuming a 3.5l not the old 3.3l, has torque. hit the gas and it moves... immediately. no so much for the 2.0l of the S, especially if you do a normal launch at 2 - 3K rpms. there just isn't much pull down there. i'm not complaing b/c i'm not a stoplight grand-prix driver, but the f20c motor just isn't a stump puller.

Yes, you feel a lot faster in the S2000 than in other cars, especially if you aren't driving. The sense of speed is much greater, and coupled with the high-revving nature, can bring on the adrenaline (or fright) a lot quicker.

You might not get the same amount of force pushing you back in your seat, but the push lasts longer and gets stronger with revs, as compared to a torqy car.

Example:
If you are cruising at low rpm, then stomp on the gas, you will accelerate slower than if you did from the same rpm and road speed in a car like a 350Z, Mustang, Corvette, etc. You have less torque at a given rpm, thus making less power, thus less acceleration.

The only way you make up for it in an S2000 is by being at the high revs the others can't achieve (ie, in a higher numerical gear for a given road speed) which gives you more power for a given torque (and more torque at the wheel due to the extra gearing).

 

I really dont understand ppl who says S2000 doesnt have enough torque at low-rpm.

I have been drove many other 2.0 engine(European,Japanese,American,Korean engines)
I even drove V6 2.0 engines.

From 2.0 N/A engine, F20C certainly have pretty good low-end torque.
Of course it doesnt have much torque as V6 3.5 or 1.8T but F20C certainly have good enough torque for 2.0 engine.
Compare to V6 2.0 engine which seems to be most torquey 2.0 but still there isnt significant difference.

Also F20C has enough torque for only 2600lb car.

 

It's because there's a noticeable difference in torque levels of the two different cam profiles. I'm rather confused and disapointed about it, but I can deal with it.

 

Whenever someone mentions torque, I can't help but think about my dad's old corvette. The feeling of the seat eating your rear as you stand on the throttle is something not too many cars can duplicate.

 

HUH????? name one.

Unless you've gutted it, the S doesn't weigh 2600lbs!
