I am honestly so tempted to exchange my rental property for one of these im sure it was for sale for around the Ł110000.
if only I could justify it in my mind like I do my property as an investment, problem is itl be worth about half the house in 5 years

Congrats to all concerned. Would love to see the data log to see at what point Power really counts. The Topend splits will be incredible.
Did a few maths a Cossie would need 1170bhp min to reach such high speeds & working backwards that GTR could reach 200mph at Brunters with only 630bhp. An incredible car with incredible grunt .

to be fair to the yb though its got almost double the capacity, although its a fat arse the weight is far outweighed by power once the speed gets high isn't it rod ?

What are the rules for the top speed runs? Do you have to exit the corner at a certain speed? Excuse my ignorance as I know very little about it, I assumed it was done from a standing start?

Awesome speed, wouldn't fancy it myself lol

You can pretty much get to the same speed from a standing start as you can exiting the corner so thats why most drive the corner. Less strain on gearbox and diffs from a launch.

Was just about to reply and say Im amazed it could go that fast with such little power and I was expecting more like 1200-1300, but I guess it just goes to show how much more slippery the GTR is than the old sierraswe are used to figures from!

237 is just mental in such a small space, must take some serious balls to hang on till the last possible second to break at that speed given the lack of run off etc!

Epic epic stuff!

The thing to remember is that a fast car like this can get to probably 180mph or so within a few hundred meters.

So the difference between starting from 0 or starting from 180mph at the start would only be a couple of seconds more acceleration at the top end, ie even with such an extreme example, it would only be a few mph difference.

When you take into account that when you come round the corner hard you cant get on the power quite as soon etc, then like Rich says it really does come out in the wash and make a tiny difference.

I bet that GTR is fast enough that it could give a mclaren F1 a 100mph head start and still easily beat it to 200mph if it started at the same time at 0mph, lol.

Exactly right. The corner puts less strain on the drivetrain than a Launch the aim is to get straight as quick as possible to get max time on the throttle. Shead man had it to perfection taking all the runway & just & i mean just getting the wheel on the grass on the far side he does it every time f**k knows how . Its a pity he has quit cos I wont max out my car like Mark.
You have to remember that 100 metres gained at the start is only 1 extra second on the throttle at 210mph so a standing start makes no difference .

The way the speed was increasing, even at the top end makes it look like this has got more in it too. I doubt I can even imagine how fast this feels when accelerating!

A car of that sort of performance will be doing around 120-140mph at the 1/8th mle from a standing start.
So that's approx 200m. So probably no real difference doing a standing start from the back of the straight as opposed to exiting the corner around 100mph anyway.

As for each 10mph increment....I'd guess that up to around 200mph, or maybe a little more depending just how aerodynamic they really are....they would be hitting each 10mph increment in around 1 second.

So 1 more second at the end of the track could make a huge difference.

no one said it was special! but must admit i thought it was pretty special when it did well over 1000hp on a bar of boost and seen as one with smaller turbos has done 237mph then I think most would agree.

and both engines were built by the same man.

The only Mercedes fit for a man that owns a 200+mph Cosworth would surely be a Brabus? Pure grunt and comfort.

Cool, thanks for the replies, like I say I know bugger all about this sort of thing, it's hard to imagine how relentless the acceleration must be to reach that speed in that distance.
