Hi. I have a new, 2004 Berlina with just over 800 miles on it and I'm trying to understand my car as best as I can. I would like to see the torque curve on a 2004 S2000. I guess a good title for this thread might be "Torque curve for dummies."

I'm not a car expert and frankly don't understand a lot of the terminology I come across when I read about dynos and measuring them. I would merely like to know where the sweet spots are regarding torque when I'm driving down the road.

The car feels and sounds good at 3.5k rpm and I'm wondering if there is a nice flat spot there. I realize there is a huge leap at about 6,000 rpm and that torque peaks at 6,800 rpm. However, I am interested in where to keep the rpm when I am cruising

Does Honda have an official dyno graph for the 2004? Can anyone help? Thanks in advance.

 

It depends on your driving style. I would recommend driving around in different gears and seeing what you're comfortable with. For example, find a 45mph road and try it 4th and 5th gears. Hows the noise for each? Does the car accelerate well enough in 5th if you need to speed up?

There's really no special rpm to target - the torque curve is relatively flat until you get to 6000rpm. No special bump at 3000, 4000, etc. (Unless you have an aftermarket intake, which can add a bump somewhere due to resonance effects.)

 

yea, it's kinda flat, but VTEC cars inherently have 2 torque curves, smoothed out into one. it's strong at around 3K on the small cam and 6800 on the big one.

 

The torque curve is very flat with this engine above about 3000 rpm, with the small bump at 6000 rpm. There are no definate "sweet spots", but realize that just because the curve is flat doesn't mean that the car will accelerate as well at 3000 rpm as it does at 5000 rpm. Horsepower does count...and hp and torque are equal at 5252rpm.

 

What do you mean by "equal?"

Maybe he means that the HP at that RPM is the same as the torque in lb-ft but that really has no significance. They are both just numbers.

 

You guys he has an 04' so the it has more torque than previous years. Let me see if I can find a dyno sheet.

 

The red line is the base run w/o Comptech Supercharger.

 

Shawn, (UL) explains where the primary and secondary torque peaks occur, it's a video.
