Hm, so all S2000's driven by the same driver in the same location at the same time should have the same 0-60 time?
"In theory", yes, HOWEVER, not even the same driver can always duplicate his own performance each time. I mean, look at the printouts at a drag strip and you'll see the same driver, in the same car, in a subsequent run, will have slightly different numbers. 0.3 seconds is not a really big difference on a 0-60 run for a car that is as hard to launch as ours.
If you gave no concern to breaking parts, played with tire pressures (very high in front and low in back) and putting a warming blanket on the tires before a run, I'll bet you could get an S2000 0-60 time closer to 5 seconds flat (maybe less). It wouldn't be me or my car. Any volunteers?

Pump them fronts up to the max pressure as indicated on the tire. Drop the rears down to 25 or so (less if they're not too squat looking). Make sure they are good and hot (drive around for a bit as they won't take long to heat up at reduced pressure). Then go give 'er.

I need to get a Gtech again. When I used to use it, I would run it while also running at the track, so I could compare the Gtech time with the calibrated track times, giving me an idea of whether it was running accurate or not.

calibrated and used correctly, the Gtech is pretty accurate. I was impressed. lol.

I usually use 44psi in the fronts and 22psi in the backs when I run at the track.

Mind you, he does have "gears", so this might give him a bit of an advantage.

The AP1 should actually have a quicker 0-60 time. The AP2 has to shift into 3rd gear before hitting 60 and the AP1 does not.

Not necessarily. Like in final drive gears, if the acceleration of the AP2 in the first 2 gears is quick enough to compensate for the time it takes to do one more shift, then the car can be just as quick to 60. Since the AP2 is gear limited to about 56 mph, it is quite conceivable that 0-56 mph, the AP2 will smoke an AP1. It may come down to how fast the driver can shift.
For example, an AP1 with 4.77 gears will also top out at 56 mph in second, yet it has been proven here by ItalianBucwheat that the 0-60 times of the 4.77 car can be as much as 0.05 seconds faster than the same stock geared car (the average of his runs was 0.4 seconds quicker). It is obvious from this example that a "geared" car can accelerate quick enough in the first 2 gears to more than make up for that extra shift required to get to 60.
We have often talked about the AP2 as having gearing in the first 4 gears as being "similar" to an AP1 with 4.44 final drive. In fact, it is closer to an AP1 with 4.77s (in the first 4 gears on the AP2). Therefore, based on this evidence, I would say that the AP2 may have a slight edge over the AP1 in the run to 60.
