Just a sidenote about the "160km/h (100mph) in 12.1" secs claim for S2000. I did some search on S2000's times and around 14 secs is the time for the 0-160km/h. this sounds more or ess rights .... S2000 does about 6secs for the 0-100km/h (60mph) and then needs aout 1.3 secs for every 10km untill the 3rd gear - ie. 110km/h in 7.3, 120km/h in 8.6, 130km/h in 9.9, 140km/h 11.2. Then you shift to 3rd and accelerate at about 1.5 secs per 10km - ie. 150km/h in 12.7 and 160km/h (100mph) in 14.3. I cannot see the S2000 from 100km/h to 160km/h in 6secs ... that is acceleration of 1sec per 10km/h - that is the accelerative force in 2 gear, not 3rd or 4th.

All the tests that I can find get 160km/h (100mph) at about 14 secs, though, I have not tried this myself so if someone else has different numbers or has experienced otherwise, then please let me know.

Like i said before at the 1/4 point, the car is doing about 106 MPH and this takes about 13.6-13.9 seconds at best. SO if this is the case that means you are travelling 100 MPH BEFORE you hit the 1/4 mile point.

If it was to reach 100 MPH at the 14th there is no way it would have a drag strip trap speed of 98.5 to 102.5 at 13.6-13.9 since you would have to be travelling from 103 to 106 MPH to do so.

I don't understand why you insist on pressing this. You are speculating and making minor calculations on something that a cartest does and also takes 100 other factors as well. Here is a picture for you from cartest.:
BTW i warmed up the air temperature to about 60F to reflect you warmer temps, it is damn cold here still, this is why 100 MPH is now 12.2 instead of 12.1



Here is one in the metric system:



Now remember you are taking australian mag times as a referance and as we all know they are not a good one. Cartest eliminates driver error and is extremely accurate of OPTIMAL REAL drag strip times which magazine times even in the U.S. are not.

You have to trust me on this one, cartest has proved to be the real thing time and time again. Margin of error is extremely small since nearly all the relevant factors are accounted for.

Finally Buddha sees the light.

Where did you get that cartest program, Sev?

IS200

Blau-blau,

Yes, I do own an 01' VIN#368 S2000.

He probably did poorly on the 0 to 62mph run because of the "anti-wind."

Launching the S2000 is a little bit trickier than conventional manual cars. I think the reason for this is the fast engaging clutch. I've noticed that the clutch "engage play" is very short for the S2000. Most cars probably have 3 to 4 inches of travel for engagement and disengagement of the clutch disc. In the S2000, this play travel is quite short at probably 1 to 2 inches. This results in a quick engagement of the clutch if your left foot isn't steady in slowly releasing the clutch causing a bog down if the revs are not matched. Thus, the perception of a car that is more difficult to launch.

Obviously, more travel in the engagement and disengagement of the clutch means a .05 to .1 slowdown in launching the car in race situations.

("engage play" is my term for the point wherein the car slowly moves upon initial release of clutch until full release.

figure 1. I--1 inch--(engage play)--2 inches--I (firewall)

So, in the figure above: When we depress the clutch for the 1st inch of travel, nothing happens. Upon reaching the 2nd inch, the clutch is slowly disengaged. Pushing another inch, fully disengages the clutch. This is the "engage play" region. Pushing 2 inches further doesn't do anything but reach the firewall. Hope, I have not confused you.

Unicron,

I think they should have used the yellow unit instead of the black unit for the Tsukuba race. Remember, the yellow unit was 1st place in the autocross (gymkhana) and it trumped the Sylvia and Integra towards the end of the show. The red one did quite well at the "rural" course as well. I think the moral of the story is black cars are slow. =)

I wonder how silver would have fared?

I was able to calculate the circumferance of our rear tires and add that in the program. Thanks to that the speeds in each gear are very close to the real ones now. I also saw on RM racings sight an s2k showing 119 MPH being dynoed in 4th so supposing that is a bit off... 4th hits 117 here.

Guess what, the car accellerates noticably faster now and produces better 1/4 times...
