Yes...

And not

Bruntingthorp is the longest place there is so no not longer than say a 
mile.

But the point was that remoulds were good enough for 150 on the road 
sustained!

Drag isnt. It goes up with the square of the speed but what is stable at
150 
is still stable at 300 unless there is a large lift component.

Its not common because they are engine guys but it happens often.

Nobody ever said the vauxhall was as safe or even safe! Who cares I 
certainly dont and would after giving it a look at give it a go!

Different argument mate!
If you behave and think like a drag racer (as I do) its part of the 
fun/attraction.
