What does an 840bhp 911 do on its day off?

[Speed]

Ah right, My mistake

Speed

On the contrary I think at this level its very difficult to mod an existing road car to hyper car levels, koenigsegg's/enzos/veyrons all have lower drag coefficients and are designed for speeds over 200mph, plus its far easier to tune an 8 litre v16 to 1001bhp than it is to safely get a 3.6 litre into the same ball park.

Yes it can be easy to get face warping performance out of something like a skyline or evo but they're not in the same league as this.

im talking in the same sense of the porsche it isnt a standard porsche it was modified by a company

[schrickvr6]

The veyron was meant to have 1600bhp but due to threats of lower speed limits on the roads this was reduced to a measly 1001.

Did anyone read Top Gears "diary of a Veyron development engineer" - its quite amusing and basically boils down to where they can fit another turbo (like the seats, the boot, the famous bugatti watch, etc.) and how can they put out the fires

Ultima cars are produced about 2 miles from my home, often see them heading over to MIRA for track days. Lovely cars and if anybodies interested they are made in Hinckley on the A47 just behind Safeway/Morrisons. Pretty sure you can take a look around their garage if you ask nicely.

Trouble is with with such high speed you need literally no downforce, but with no downforce its extremely easy to loose the car. Personally im not sure if the cost of having to produce these cars is really justified though, i mean do people really care what hypothetically would be the fastest road car? Sure its a great title, but when its coming down to 1mph, its hardly as 'important' as a jump in 100mph. And until we strap jet engines to cars that isn't going to happen with a combustion engine.

9ff built the 911 described.
They are considered a manufacturer in their own right in Germany, much like Alpina and AMG. Although you can take your car to them for modification they can also sell you a '9ff' straight from the factory.
At the end of last year EVO ran a feature on their then fastest 9ff which had been quietly blowing all the opposition into the weeds.

Bonkers the lot of 'em. Someone please give them a 997 to play with

What he said. 9FF are AFAIK registered as a manufacturer in the same way Ruf are. Porsche sell them a new bodyshell or a partly built car, and they then finish it off with their own bits.

I find it surprising that a 911 needs 840bhp to hit 240mph while a Maclaren F1 only needs 650- I can't believe it's that much less aerodynamic. I'm not sure I agree with Knox either- I reckon one of those crazy 1000hp japanese Skylines or Supras would easily do 250mph with the correct gearing (especially the Supra, which is 2WD and pretty aerodynamic).

there is some of those supras with the skyline stragith six slapped in kicking out around 2000 bhp happarently happarently ....

the mclaren beats the porsche because it was designed with a free hand and no budget and in a wind tunnel so its bound to be a fair bit more aerodynamic and at those kind of speeds im sure your gonna need all the help u can get ...

plus the mclaren is the ultimate car , and for me it probably always will be !

[weebroonieuk]

tell u what tho id fckin luv to stick my head out the window at that speed

imagine a bee hitting u at that speed

Thinking about it there was a bright yellow supra in max power years ago, tuned to some ridiculous level that did 249mph on some salt flats, it was however no-where near street legal, The supra may look like a nice slippery shape but its not all about low drag at those speeds you've gotta have just the right amount of downforce aswell, its downforce and not engine power that limits the enzos top speed to 217mph

[Rave]

True I guess. I have a video somewhere of an RX-7 taking off spectacularly as it goes over 200mph on some salt or sand (presumably at Bonneville).

However slippery the 911 has managed to develop into, the F1 has no comprimise when trying to hit the high notes. For starters the 911 front screen is very upright, the sloping rear promotes lift and it's nowhere near as thin as it used to be.
Even so you'll note this particualr 9ff has very little in the way of spoilers for as has been pointed out, downforce is umm-bad when trying to attain the highest speeds.

As for the various Japanese machinery. The majority are closer to a Landie in the aerodynamic slippery-stakes!

[Firelord]

9ff have done a fantastic job and the evo article on that run was fantastic

They also had in evo about how hard it is to reach xxx mph and its not just power etc thats the factors. It was something ridiculous of you needed an extra 50bhp or someit to go an extra 5 mph over 200mph.

Will dig out article

[weebroonieuk]

i think youl find it has alot more to do with aerodynamics at those kinds of speeds mate ,
some of them like the mclaren have enough power to hit there rev limiter in 6th so u can give it another 500 bhp it will only make more noise an empty the fuel tank quicker
