At what elevation and temperature were those runs made?

 

DavidM,

What are the 1/4mile speeds on your summary?
As we know the S2000 is tricky to launch, however the 1/4mile speed is less susceptible to bad launch or road traction.

In US, the fisrt C/D test showed 0-60 in 6.8s and 1/4mile in 15.1s @96mph.
Subsequent C/D test showed 0-60 in 5.8s and 1/4mile in 14.4s @98mph on the same Red Car.

You can see that there is more time variance than speed variance.

M-Roadster and BoxsterS results are within 1-2mph of S2000's.

On lap times, S2000 is better on faster corners and worse on closer corners.

2kturkey - I'll check out the BP fuel ... been using Optimax exlusively for a while. I'm going to line us some Commodores SS (the 5.7L) ASAP and see how I fare with my S2000. Also, as I said, I have a HSV R8 at my disposal. In regards to the local magazines - it's probable that the times they're getting can be improved on, though, I would presume that in relation to the other cars that they test, it should show the proper relative performance (acceleration) of the cars. ie. 911 is quicker than M5, which is quicker than NSX, M roadster and Boxter S, which are quicker than S2000. Going by the hierarchy that the local magazines got, the S2000 should be in the same acceleration league as a Commodore SS (5.7L), Boxter 2.7, Audi S4 .... I'm still pressuming that the the HSV R8 auto will be quicker in the straight line. btw, 2kturkey, have u managed to line up any of 'these' cars? If so, how did u go? Also, where in Melbourne do you live?

Sev, those runs are done with 2 people on board and full tank of fuel. Also, they run then in 2 directions and work out the average. Not sure how this differs from the testing procedures in the States or UK. Also, all the runs are done on the racetrack ... elevation here in Aus is not much to speak of - it's barelly above sea-level everywhere :-) The temperatures vary on what time of the year the tests are run - it can be anything from 10 - 30 degrees Celcius. Though, the Honda time was done about 4-5 months agho so I'd say it was about 20 degress Celcius then.

Asin, the 2nd number is the 400m sprint ... which is more or less 1/4 mile (ie. M Roadster 1/4 mile time is 13.9secs).

 

David, I rarely have the opportunity to really challenge anyone at the lights. I live over in North Balwyn and there are not too many "stoplight hoons" living out this way.

I'd be interested to see how you go against the Commodore SS and HSV R8 and am prepared to participate if you like. I am not sure there will be that much in it - my last car was a '91 Firebird 5.7 (pre-LT1)which I brought back from Canada. It certainly wasn't as fast as the Stook but was great for laying rubber at the lights with.

I don't know how many ks you have put on the S2K at this stage but I have 20,000 up and am well and truly run in . Which neighbourhood/road do you plan to use for your "comparative testing"?

 

lol 2kturkey :-) I don't get involved in too many 'trafic light drags' either ... though, I often 'drag' people I know at such occasions - that way you know that you're both trying and trust each other. So my plan is to catch up with people that I know have the cars I mentioned and organize a 'drag challenge'. Usually, things like this go on at night (when it's dark and there's very little traffic) and often we do it on Nepean Highway 'cos most people I know like around there. ie. Brighton, Elwood, Bentleigh and Aspendale. Another opportunity for things like this are 'racing courses' that they do at Sandown ... I've done 3 (or 4) of them and you have a good variety of cars there so it's eazy to see who has a faster/slower car then you - after all, everyone there has the pedal to the floor :-)

I see you live around Kew Bolevard ... will have to get the S2000 there - used to spend a lot of time there with my friends and our cars :-) Though, at the moment, my S2000 has only 550Km on it .. so it's not even run in. It will be another week or two before I able to put the foot down properly. Though, if you're interested, I can borrow my fathers HSV R8 (heck, I'm sure he'll want to caome :-) and we can try and line it up with your run-in S2000 ... if you really want, I can get an MR2 and TVR Cimerra (4L V8) involved pretty easilly too. We can organize to meet somewhere at night during the week and see how it all goes.

 

Okay, you're on. I'll email you and we can take this offline. I may be able to line up a few others too, I have a colleague with a Dino 308 who lives in Brighton and another with an Auddi TT convertible in Elwood. There may be some other S2ks, 'teg Type Rs etc. interested.

That TVR Chimera sounds like fun - that's a vehicle I can really admire.

 

Cool, send me an e-mail 2kturkey. Also, I have another theory why the S2000 have not posted a 'fast' time here in Aust. From every article I read, they complain about a weak clutch ... they say that it starts slipping after a couple of 0-100 runs. In one article (where compared to Boxter2.7) they said that the S2000 got slower with each consecutive run (because of a slipping clutch) while the Boxter got quicker with each run. That would lead me to believe that the 6.6secs to 100km/h was achieved on the very 1st run. It took them several runs to finally get the 6.34 time for the Boxter. I'm sure that if they could get the 1st start right (or had a better clutch) then they could get into low 6s here.

Though, that still does not explain how they manage to get into 5s in the States and UK.

ps. How are you people finding the clutch? ... I already think that it's too weak but then I'm used to a custom 'racing' clutch in my old car.

 

David and all,

In portuguese auto magazines the best numbers i have yet read for the 0-100kmh launch on the S2K was 6.4sec. In the same magazine the Boxster S got 6.0sec.

Now to the different US/Europe/Australia numbers i think the explanation is pretty simple:
60mph = 96kmh ----

 

DavidM, MX5dude, I hear what you say. In my opinion, the extra time from 60mph to 100km/h should take around 0.4 to 0.5 secs. Both the Stook and the Porker can hit 100k/mh + in 2nd gear.

With regard to clutch slip, I had exactly the same problems the first few times I tried fast stop light starts (dropped the clutch at 6k and ended up hitting 9k in 1st and 2nd for about 20kph of forward speed). Now that I know how to side step the clutch I don't have this problem any more.

Let the games begin!!

 

Yeah, 60miles is 2.5Km of 100km ... though, 2.5km is 2.5% of 100km. That means that 6.0secs for 0-60miles should translate losely to 6.2 secs. I know that the acceleration is not linear but I don't think that it takes .5 sec to climb 'extra' 2.5km/h. Concidering that they are running 5.5s in the states, that should still translate to a sub 6sec time here in Aust ... which stil hasn't happened.

ps. S2000 reaches 110km/h in 2nd gear so there no 'extra' shift.
