9ff building 900hp gt1 inspired supercar

has anyone heard about this:

"Tuner Turns Car Maker

The Dortmund-based Porsche tuning outfit, 9ff, has attained the same 'car maker' rating as rival Ruf. Even before its change of status, 9ff had begun work on its own supercar project, which although very loosely 911-based and inspired by the GT1, comprises mostly in-house-designed components. The 9F-GT1 has a tubular spaceframe and mid-mounted 900bhp 4-litre flat-six.

Jan Fatthauer, 9ff's founder, says the car will 'move the company to a new level', both in terms of public perception and performance. Given that the company's 840bhp conversion on a GT2 recently eclipsed the McLaren F1's 240mph speed record (076), it should be quite a beast. But Fatthauer insists that it will be 'a production street car, not a racer, and while it will have crushing performance we want anyone to be able to drive it'.

Fatthauer also promises that the car will spend time in the wind tunnel - 'although not too long, it's very expensive!' - and will feature race-style adjustable suspension.

Meanwhile, the company has launched a 4-litre conversion for the 996-series 911's 3.6-litre engine. With 9ff-spec twin turbos, these engines are available in several states of tune between 650 and 820bhp."

Also Czech news site but i don't understand it

my silly prediction is that IF this car comes to fruition, it'll beat the veyron's top speed (and dauer :D ) because:

1. 9ff knows how to make a high speed car (eg. their 9ff 911based car went 241.1mph/388.01kmh, koenigsegg ccr 241.01/387.87kmh)

2. power to weight exceeds veyron (assuming this car weighs around 1300kg [porsche gt1 was 1250kg] )

veyron 1001DIN hp/1596.95kg(or 3520lbs)= 626.8hp/tonne
9ff 900DIN hp/1300kh = 692hp/tonne

all pure speculation :D

Anyways, 9FF is already offering a 910bhp, 930Nm conversion for the 996 gt2 on their website.

Can someone please translate the Czech website for me? :) Thanks

please if anyone has more news let us know, thanks

Talking of which: What happened to Ruf's own supercar? They'd embarked on their very own supercar project last year and there were pictures of early prototypes testing but no news since.

Huh! So he's building a supercar - presumably one that will do well over 200mph - and he seems to think that proper wind-tunnel testing is not that important (i.e. will be limited because too expensive). How expensive will it be (in legal expenses) when customers report that the car takes off when you go fast in it?

[flemke]

Weight is almost irrelevant to maximum speed. Weight comes into play when you're talking about rate of acceleration, and then the other factor is torque, not horsepower.
Maximum speed is (almost) only a matter of horsepower in relation to coefficient of drag times frontal area.

IIRC when they were going for Vmax in the 9ff V-400 the rear wing broke at 300kmh

This car will be very interesting though, and i did not know they were a manufacturer either.

but one thing in their favour is that they actually achieved the top speed of 388km/h or 241.1mph with the 9ff-V400 (despite broken wings ).

900hp will be plenty while a car inspired by the GT1 will surely have a relatively low Cd.

Hopefully this project will actually happen as it will be interesting to see 9ff going for a crazy maximum speed, anyway I heard the RuF prototype project was scrapped.

So I take it that Ruf have never broken any parts in testing?


IMHO these guys have got the balls to push the envelope, so let's not pan them for at least trying to achieve something.

one word, Gemballa keep an eye on these guys

No question, it is great they are doing this sort of thing, makes life interesting...

had a look at some pics of the Ruf prototype, dunno about you guys but i don't dig the styling.

hope to see 9ff take the max speed crown from Veyron, I believe they're well-qualified for it.

(I know the Veyron's done several passes above 400kmh at Ehra-Lessien monitored by TUV, read somewhere the two highest speeds were 405kmh and 411kmh).
