You like drama dont you. No 200 isnt that fast. I have been on turbo 
streetbikes that can do that. It does not feel any faster than 150 or 170.

Just numbers. Many cars at many events are severely modified and do these 
speeds.
Even my old V8 sierra tow car would do 150 with its ye olde knackered 1.6L

suspension. It had Colway 205/60/13 REMOULDS on which were supposed to be 
safe to 70...
It was completely stable and no problem. Used to throw chunks of tread off

occassionally but what do you expect...

You are only talking about another 33%  I may have splashed out on some 
proper tyres for that! But that car would also have been fine with anothr 
third more speed.

In the main no. Maybe a few percent of mixture and a degree on timing, a 
fraction more or less boost. If it runs on a quarter without breaking then

there shouldnt be a problem. Obviously the further you go even in a
shopping 
trolly the greater likelyhood of something failing.

No its because top fuel engines are very unpredictable and do all kinds of

evil things. But we are talking about a 2000bhp engine not a 5 or 6
thousand 
bhp bomb.  They are physically on the borderline of strength. They are an 
explosion waiting to happen. We are talking about a road car.

Many pro mods make this much power and run several seasons on a single 
engine.

No since its a road car its probably bigger... It easily could be if it
was. 
But I suspect there isnt anywhere you could go 250mph for four and a half 
mins anyway!

Yes but you cant and wouldnt do 250 for long in a veyron either...
And thats only 250 not 300 400 or 450 is it?

Nobody ever mentioned safe or cost.
