It wont reduce times by much and the increased final drive will actually
help to put the power down as less torque gets delivered to the wheels but
up to a higher speed. If it effected its quarter mile terminal speed by
more
than a few mph I would be amazed but it could ad say half a sec max to the
time.

But it was a mclaren, and I was on a bike with low power to weight
compared
to the vauxhall!

Because both have a similar top speed potential but the vauxhall has much
much better power to weight! It will accelerate TWICE as hard.

With the correct gearing of course it can do it.

Flat out it is. It has the power to weight of a moped with a fat bloke on
it.
The Vauxhall has about ten times that power to weight and double the
veyron.

Its a slow low powered car.
Put the veyron on the drag strip compare that to the vauxhall and you will
see that its just driving off going on a shopping run.. Its a different
world of performance.

We cant. But why not? My V8 nitrous sierra (was an old reps 1.6) with
knackered suspension and Colway 205 60 13 remoulds would go 150 for mile
after mile. Whats another few mph?

I dont think he quite gets how powerful and how hard this thing lauches
and
goes! Its accellerating harder at 150 than the veyron can off the line!
May
I suggest a trip to the drag strip and watch a few pro mods go. They run
the
same sort of times. Once you have had your idea of power recalibrated you
will just see a veyron as a low powered streamlined car that does its 250
due only to good aerodynamics and a long 2 plus mile run up.

In your mind it seems to. Its really not a problem! It might not be as
good
as a veyron but that does not make it dangerous or unstable.

The vauxhall would absolutely murder the veyron under ANY speed range
acceleration. Gearing allowing of course.

Means very close! noddy = http://pbskids.org/noddy/
