Lee got it right without me even needing to explain.
1) Its the speed range I use round CC for example +other tracks.
2) I want to use a starting speed that will not induce wheel spin,..this is an engine performance test not a tyre grippiness test.
3) I want to put in third , floor it, then have time to get the stop watch ready before all hell lets loose.

4) I want a high speed ( long run) so even if I were half a second out (unlikely) the percentage error on the run is minimal.
5) Anyone can try it on a private road without expensive equipment.
6) Oh and Big Show can have a go in his car to see the difference.
7) This test will realy sort the big power cars from the dreamers, and show as quite a few seconds difference.

1320.. dont you realise by having all the 0 to.... figures for a car as you have listed for a £300,000 Porsche ,you also have the 60-130 times aswell.
Let me explain :-
0-60 ...3.5 secs
0-130...14.7 secs
14.7- 3.5 = 11.2 seconds .....this is the 60-130mph time.
Now has anybody got the same for an R8?
