Got an AP-22 (http://www.race-technology.com/WebPage/Products/Accelerometer/ap22/Ap22Introduction.htm) to play with today and took it out for some fun in the 205.

The result:

0-10: 1.03
0-20: 1.97
0-30: 2.95
0-40: 4.28
0-50: 5.33
0-60: 6.53

That's in a standard mi16, no spare, just me driving (75kg). The road was damp, but I drove about as perfectly as could be expected - I dont think it'd be much quicker in the dry, maybe a bit.

I think the straightness of the in-gear acceleration rate is down to it being wet, grip was the limiting factor, not the engine's power curve? That said actually you'd expect it to be the derivitive of a power curve, and f you approximate a power curve to a parabola then a straight line for acceleration is right I think? :)

And to add credibility to the 6.53 second figure we have a revlimiter hit at 63mph after 6.95 seconds - and that can't be subject to error really, the speed is spot on for max revs in 2nd :D

Slower today :(

6.82 and 6.92 on two runs. Gearchange was 0.05 slower than yesterday on both runs.

My car has a nasty flatspot, which sometimes isn't present, yesterday it wasnt, today it was making a noticeable dip in the curve at 25mph on both runs :(

100 came up in a staggeringly poor 17.42 seconds!

It's also pretty hot out today which I guess wouldn't help.

Numbers in brackets are difference from yesterday's damp run. Got a better launch, but you can see how the car gets hit between 20 and 30 and 40 and 50.

0-10: 0.99 (-0.04)
0-20: 1.91 (-0.06)
0-30: 3.03 (+0.08)
0-40: 4.39 (+0.11)
0-50: 5.54 (+0.21)
0-60: 6.92 (+0.39)
0-70: 8.97
0-80: 11.00
0-90: 13.98
0-100: 17.42

standing quarter recorded as 15.46 @ 94.6mph.

Gearchanges made at 38mph, 61mph, 84mph - so it seems I changed up from 3rd to 4th 5mph early (my revmeter doesn't work so I have to go on engine note :)).

The other run was:

0-10: 0.93 (-0.10)
0-20: 1.81 (-0.16)
0-30: 2.94 (-0.01)
0-40: 4.26 (-0.02)
0-50: 5.42 (+0.09)
0-60: 6.82 (+0.29)

but then I fluffed the change into 3rd ;)
