 140ish mph, so something of a walkover for the vaux..

As I said there wouldnt be much in it. But the Vauxhall would be there in 
half a mile roughly and the veyron? Dunno... Probably 2 miles judging by
the 
Maclaren F1 we were playing with at bruntingthorp.

It was getting 220 through our timing lights after 1.5miles of runway. 
Interestingly my own new un run in stock 1100 wp suzuki (derestricted)
left 
it for dead coming onto the main runway. From 35mph up to say 140 the bike

pulled away so fast the car was a small dot. From then on the bike takes a

further mile to hit say 165 due to the bad aerodynamics. At about just
past 
half the runway but the dot gets bigger and bigger! At the timing lights 
just before the braking boards the car is in front of me by several
lengths 
and triggering the lights at over 220. At this point I was doing maybe 173

to 175 according to the radar so it comes past like you are parked.  So
the 
cars acceleration from 120 on is much better than the bike and improves as

speed increases. Power to weight is less on the mclaren but its slippery 
shape makes up for it on a two mile drag. But not by much. On the road
with 
bends, traffic etc it would lose quite easily.

In the same way the veyron would lose on a motorway chase because the top 
speed is pretty impossible to achieve - no time/space - but the vauxhall
can 
accelerate massively harder. Throw in some corners though and a roads and
it 
would be the veyron...
