I've been trying real hard to find somewhere a torque and power curve (vs revs) for the S2000. I can't seen to find one anywhere ... I can find one for almost any other car, but not the S2000. Has anyone seen one? Can anyone point me to it (if it exists) or post one up here if you have it?

I'd like to know exacly what power/torque the S2000 has at any given revs.

 

Just search for some dyno runs on this board and you will see the representation of the power curve at the rear wheels. The power curve was shown on the Honda Japan website at one time but that site is always changing and (since I don

 

I did a search for "dyno" and read though all the posts that came up (took me a while). Though, nowhere could I find anything that resembles a power/torque curve or figures that would state power/torque at given revs. If you know about such tread then could you possibly point me to it?

 

Here's a link:

Click on "Translated Articles", then "125 hp/liter engine"

 

Excellent!!! So if I read this graph correctly then here's some conclusions/deductions:
- 190+Nm when over 3000revs
- 120+Kw when over 5600revs

The above numbers compare nicelly with maximum power/torque of a any other good 2L engine.

Some more numbers that put it way out (and above) the 2L category:
- at 6000 revs : 130Kw/210Nm
- at 7000 revs : 160Kw/218Nm
- at 8000 revs : 175Kw/218Nm
- at 9000 revs : 165Kw/190Nm

So in summary, bellow 5600 revs, the car will drive like a very nice 2L but above 7000 revs it should give some serious perfornance cars a run for their money :-)

 

You must not have really searched as there have been a number of posts on this subject.

But here is one for you

 

I love that HP curve or should I say slope. It looks like the power curve on a turbine engine! Faster you go the faster the engine pulls and more power you get out.

 

Thanks krazik-s2k, that's exacly what I couldn't find :-)

Though, can you tell me what is the difference between the blue and red graphs? ... I did notice that they're a bit different - I take it, one is with some kind of mod .. right? If so, then what's not standard? Last of all, what fuel was run in the engine (ie. how many octanes)?

Also, am I right to pressume that this is the output at the rear-wheels and not at the engine?

 

DavidM, these plots were done after Rylan (krazik) installed the HKS cat back exhaust. That is the mod that made the difference...
