Hey take a look on this thread.

I asked for a vid of the S2000 with a HKS and reecespieces
put on some good vids. One of these is "HKS with passenger". He has a stock engine. The vid shows the dash as he easily breaks 60mph in 7 sec.

s2kblk,

I was pretty sure I was driving the S2, instead of the Lexus. I was shifting remember?

Elviscos,

I have to turn on the air-conditioning because it gets quite hot here. I guess, 0 to 60 figures are done without air-conditioning huh? Must be the hot weather that sapped my performance.

10secs - 1 sec(passenger) - 1 sec(air-con) - 1 sec(hot weather)- 1 sec(stop watch) - 1 sec (normal launch) - 1 sec (lousy shifting) = 4 secs!!! Hah!

911s here I come! Now, if I go on a diet, McLaren F1s should start crying.

 

--------------
How in the world do I extract those under 6 seconds 0 to 60 figures? Do I have to drop the clutch at 6 to 7k rpms at every stoplight? My friend and I timed the stook from a stop light and it took me 10 secs to get to 60mph.

I didn't do a drop clutch at high revs. I just simply floored the accelerator and released the clutch accordingly. Shifted at 8,500 rpms. We used a stop watch.

IS200, More or less what 2kturkey said. It takes good 8 secs for the S2000 to go from 0-100kph when you launch from low revs and do not ride the clutch. We did that many times and Gtech always showed somewhere around 8. In order to do 6.2 we had to drop the clutch from 7.5k and have the wheels spinning untill the car was doing enough speed for the rear wheels to stop spinning when the revs land just above 6k (ie. in VTEC).

Though, you messed up with your shifts ... shifting at 8.5k?! Why, would you do that and not rev it to 9k when you're going for 'speed'? You have to go to 9k otherwise you're going to lose a lot of time. Shifting at 8.5k in 1st will drop you to barely above 5k revs in 2nd gear and you have no power there ... 100kW/130hp is all that S2000 produces at 5k revs. You have to keep the revs as high as possible ... and you never want to land much bellow 6k. Shifting at 8.5k in 2nd also means that you're not doing even 100kph when you make the 2nd to 3rd shift and that shift costs you good 0.5 secs ... I know that 60mph is only 96.5kph and you manage to do that in 2nd when shifting at 8.5, but you're still cutting yourself short. Not only that, but the S2000 produces the maximum power at 8.7k and you never reach it. That is where you lost a lot of the time ... shortshifting.

Last of all, S2000 speedo lags and displays the 'actual' speed a good second later than you actually reach it. So you could be doing 60mph but the speedo takes a good second to catch up. Watch the revs instead as the rev counter does not have any real lag. 60mph = 8.3k revs, so as soon as you hit 8.3k revs in 2nd gear - that's when you've reached 60mph and stop timing ... the speedo will catch up another sec later.

So, one sec lost shortshifting, another sec lost waiting for the speedo - that lands you more around 8 secs ... try it again and this time redline it and time it of the revs. Let us know how you went this time.

ps. The 'other' person costs you only about 0.2 secs or so (maybe 0.4 or so when launching from low revs). Wiht me and 2kturkey in the car we managed 6.25 as the best run with 2 people aboard.

pps. the only way to get optimum acceleration when launching from idle is by getting yourself a big engined car (like a 5.7L V8 :-) ... every other car needs to be dropped from high revs in order to extract the best straighline performance.

IS200,

My previous reply was a joke...

 

s2kblk,

Seriously, I was driving the S2000. =)

DavidM,

I shifted at 8,500rpms because I keep remembering these bridges that have a load limit of xx tons. It got me thinking, if a bridge has a load limit of 20 tons. What happens when a load of 20.1 tons is applied? Would micro fractures begin to start?

Dumb as it may sound, Stook's redline is at 8900rpms. What happens when 9000rpms is reached? I know Honda engineers placed an engine cut off at 9,XXX rpms. But you can never be too careful. I think I should hate the car more.

Dang, so a properly launched Civic Si could actually match a poorly launched Stook. In the same regard, so can a Stook for an improperly launched 911. Oh well...

 

Nothing happens when you reach 9x00 RPM's aside from the rev-limiter. I've hit it several times accidentally in 1st. The car can likely touch 10,000 RPM's without a problem. I think the key is that you don't LEAVE it over redline for extended periods (more than a few seconds) of time or risk damage.

The car may put out peak HP at 8900 rpm's, but apparently shifting before that point will drop you below VTEC so its not optimal for drag racing.

Of course, why would anyone want to drag the s2000? You're not going to win on the drag strip with cars having more low end torque in short races, you're going to win on a twisty road where other cars simply can't stick to the road like the S2000.

The first article on the S2000 I read which noted they got 0-60 < 6 secs also noted that the technique used was not recommended.

You'll drop a stock Civic if you go beyond 60mph no matter how you launch it.

Actually peak power is at 8500 rpm's and redline is at 8900 rpm's. Do a search and you'll see that on the dyno graphs, it shows what I'm saying is true.

 

What makes you guy think that S2000 has the redline at 8.9k revs? I'm pretty sure that the redline is at 9k and that the cut-out is at 9.2k (maybe even 9.3k). I just checked through 5 articles and they all mention the 9k redline ... one is even going into detail about the engine and it mentiones the redline at 9k (where it produces piston spped of 4960fpm).

ps. My bad, S2000 produces max power at 8.3k revs.

 

I have always understood the cut out came in at 9.3 which would explain 93 mph in third that I have seen. I think that the Gtech techies would be able to give a complex formula explaining the real world to us all though.

I know that the S2000 is not a stop light wonder but there are occasions when I am at a light and just fancy a piece of acceleration against a Z3 or a Boxster or a big BMW.

If my sub 6 second acceleration is achieved by screaming rev clutch drops - Is that not how the Boxsters, Z3's, and BMW 528i times are achieved too?

Are their real world times a lot slower than their book times?

Regards,
Sam.

 

I think some cars just have torque and don't require dropping the clutch at high revs to launch well...but I don't know how they achieve their results. I'd think that spinning the tires at full throttle in a high torque car would result in a slower time...but I'm sure someone here knows...

haha, funny, I had 8500rpm's as peak power in my message to begin with and then for some reason I thought "hmm, no, its 8900??" and went back and had edited my message right after posting it. I swear though that I've heard both figures quoted - maybe one is at the crank?
