In what distance would a Bugatti Veyron beat that Vauxhall dragster?

I don't know about nowadays,,,, but not much over a few years ago, some Chevrolet pickup trucks could out accerlerate Corvettes off the starting line. cuhulin

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.

Me either but I worked closely with guys that do (Nitrous Systems, dynos etc)

Or as big as the tank you choose....

And? So what! Noboody ever said otherwise...

Mostly the bank, committee design etc.......

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.

I meant to say 0 - 60 in 2.46 vs 150 - 210 in 2.46. Originally was comparing the 0 - 62 times of the Veyron which I've seen as 2.5 and mixed up my editing.

And if they go from a 150mph start, I hardly think the Vaux is going to emerge victorious. Even if it theoretically has the horsepower, that drag gearing and nature isn't going to allow it.

The owner's family would probably appreciate a nice floral arrangement at his funeral if he were stupid enough to try it.

On unknown gearing we cant know. with tall enough gearing though it will out accelerate the veyron at ALL SPEEDS.

Absolutely irrelivant.

Of course there is! But its not major like you think!

No I suspect things like the suspension bottoming out due to exess downforce or the windscreen blowing in to be the first problems encountered if you push something fast enough. Seen it happen at long marston.

Your telling me...

It is MASSIVELY quicker accelerating at ALL speeds like 3 or 4x the power to weight. It is most likely just as fast if not faster given the approx data we have and unknown gearing being suitable.

There is nothing "humourous" about the comparison.

I own a 1961 made in Germany, Westlake Hercules Moped.(it has bicycle pedals on it.

They probably handled better at high speeds, too.

Not me I think?

Very wrong - Logic and physics dictates that the Vauxhall would totally destroy the road car at all speeds other than flat out where the vauxhall should be only v slightly faster.

No way is that Vauxhall with drag gears capable

Nobody knows the Vauxhalls final drive ratio. And in any case he could choose the best one for the challenge on the day in minutes. As for "he would be a fool to try" that would be your unqualified opinion. Personally I dont see a big risk but I am an ex serious bike drag racer, tuner, nitrous system builder, and inertial dynamometer designer and builder (amongst other related stuff) and you are what? Shelf stacker? Only a guess...

You dont understand suspension. I have driven ridden 200mph stuff with none. Not an issue.

By which you mean what? Low drag? No its going to be draggy. He does not care he has 4x the power! Or stability. One of my hats is serious high speed aerodynamics. Stability only requires that the centre of pressure is as far behind the c of g as you can manage. And n a car "some" but not exessive downforce. Thats EASY to arange with a square shaped car. Its actually harder with a low drag shape like a veyron because its " rounded" ... The point where the airflow detaches in a gusty or crosswind situation changes position. Since this is assemetric it tries to destabilise the car. Anyway TRUST ME when I tell you that an old vauxhall is easier to make stable at high speed than a jelly mould shape...

and an engine that was designed to go like hell for

As a seriously high power engine tuner and dyno designer and drag racer I can tell you now that a really high output engine will die in 2 to 5 secs if its "wrong" ... And the opposite is also true, the more boost you have the richer and more retarded ignition you need to use.

Sorry but your 10 secs is plucked from mid air simply because you dont understand enough about the subject.

He tries to hold high speeds against that Veyron's

Thats possible but still you seem to think its inevitable where I as a serious and seasoned drag racer thinks its not even an issue!

B) his engine is

If the engine breaks he just slows down and is disapointed. You watch too many films...

Physics dictates that the vauxhall with 3x the power will actually have a better top speed by a small margin gearing allowing.

or passes the burning wreck on the side

Imagination running away with you? Sorry but I have been to too many record events and drag meetings for that to make any sense.

His best run was much closer to 8 than 7 actually.

Utter nonsense. It's also limited by the ever-increasing air pressure the faster it goes, assuming there's atmosphere in the UK.

What I see is that your construct doesn't hold water. It's highly touted as doing 0 - 60 in 1 second. If it were truly accelerating faster and faster as you assert, then it should do that 180 in well under 3 secs. Nope, takes almost 8 seconds - which is the best he's managed out of many tries. Wanna bet a lot of his runs have been over

8? Clearly the speed/time is largely dependent on the early stages with acceleration steadily and rapidly degrading as he goes down the track, with boost, nitrous and best wishes from the Queen and her court.

Tom McCahill test the Vauxhall

I used to read ''Chrome Dome'' Tom McCahill's road test all the time in Mechanix Illustrated magazines.Tom McCahill would sometimes take his Labrador Retriever dog and shotgun and other hunting gear along with him and get in some duck hunting on some of those auto road test he used to do for Mechanix Illustrated Magazine.He was one of a kind. cuhulin

Yes it was and as usual you are cutting out the bits you dont like again.

No. I said that thje vauxhall is accelerating harder at 150 than the veyron does off the line. Can you not read or understand?

150 to 210 was never mentioned other than by you. Both cars will accelerate slower as max speed is achieved but the one with the biggest power and the best power to weight and the most drag will do so much later. It will still be accelerating much harder than the veyron as a large proportion of its vmax is achieved.

No I am not. The problem is that you dont read or understand too well. The typo sentence that you picked out of a huge post and cut all the rest because it made you look stupid didnt even make sense to you never mind me.

It doesent and you are wrong. According to the calculator based on the figures we know the veyrons acceleration never matches the vauxhall at any speed.

Wrong! Compared to the lower powered car its rate of acceleration is much greater and for further up the track. Its acceleration only falls off markedly at the top 25 percent of its run. And is better than the veyron at every point on the graph.

No it wont and I never said ir would! A bike has the aerodynamics of a brick. But still a cheap stock one runs a quarter mile at the same time/speed as your beloved veyron...

Although I personally know two people well who have modified roadgoing bikes that run rather fast. Dean Williamson (british drag streetbike champion for many years) suzuki turbo 1100 was road legal and it had 270bhp when I dyno tested it. it ran

8.1secs and at 170+ on street tyres with no wheelie bars. thats slower than the vauxhall. But hugely fast. He is a joiner and uses it for transport at work... It was also clocked by simon hargreaves performance bikes magazine editor, at the isle of man on the road at 212 mph with the PB Radar speed gun, and at 222 at bruntingthorpe in the rain - he said it would go faster but kept spinning its rear wheel. And the vauxhall has massively better aerodynamics than an early eighties or in fact any bike! And Woody (proper name unknown) has a draw through turbo no intercooler on an UNFAIRED bandit and it ran 214mph at bruntingthorpe with 30lb boost and it too is his roadbike.

And by a a 50mph margin and its still out accelerating the veyron gearing allowing and we dont know what gearing he has or can have.

Okay, 14.75 miles to go. If that Vauxhall

Yes it is. The vauxhall has the same max speed potential. The veyron will be left in the dust . Because: You dont know what gearing he uses. When drag racing with huge power tall gearing helps. A top fuel car only has one gear because it has the power to light up tyres in its only 300mph plus gear.

When racing drag bikes we up the "final drive" (sprockets) to allow a full

1/4 mile run with only 3 gears used. Some use two. This is because each gear takes you further without a break to change gear. It allows the engines nitrous oxide induced torque to be used off the line. We dont need lower ratios because grip is the problem. We cant use the huge power with low gearing. Gearchanges take time. So its entirely possible that he is only using two gears and a very tall final drive ratio. In fact its pretty likely... In any case we simply dont know. But I can tell you now short gearing does not make a powerful car faster! Just the opposite.

So your supposition is very seriously flawed simply because you have no knowlege of drag racing or seriously powerful modded stuff...

The chances are that he already has the taller gearing or has a box of final drive ratios to choose from...

He has more "goods" everywhere including the top end. Not only that but the control systems and launch systems to better control it than the veyron! Why do you suppose that the fastest cars on the salt flats are slightly differently set up drag cars! Unless streamliners or jet cars?

Without a doubt. As a sensible and reliable car for average joe to run on the road its superb. But it has to be safe, reliable, smooth, quiet, crashable and pass emmissions tests etc. So no way it can compete with what is basically a drag race car on the road with all the impracticality that this means.

Frankly it is miserable as far as drag performance is concerned. There are rather a lot of cars at any test day or race meeting that can do that at any drag strip most weekends.

I think its an excellent bit of engineering. But it could never compete with a dragster on the road for straightline performance.

So your statement that you keep cutting out of the posts (like almost every point I make that you dont "like") that it is "laughable" to compare its performance to a veyron is in itself "laughable". You simply have no comprehension of performance.

Given an infinitely long test straight, then the Vauxhall's 5mpg would become a factor and it could eventually be overtaken by a Smartcar!

Probably something like a Golf or Octavia SDi. Decent sized tank, reasonable MPG...

What's the MPG like at top speed though? But yes, you probably want something with a low top speed.
