Maybe the name 9ff doesn’t ring a lot of bells, but when I say they have built a car that is called the Veyron Killer I hope I have your attention! Because it is Porsche month on Speedhunters I present to you the 9ff GT9. This car is the brainchild of Jan Fatthauer, founding father of 9ff. The name 9ff stands for 9 to relate to Porsche and the double f stands for Farhzeugtechnik Fatthauer.
The numbers that accompany this car are mindboggling. Top speed is 409km/h so that’s faster than a Veyron but maybe even more astonishing is it’s acceleration. The 300km/h barrier is reached within 17.6 seconds. This is all thanks to a 4 liter, 6 cylinder liquid cooled engine that has two turbochargers. The front of the car can be recognized as a 911 GT3 but then all comparisons stop. The rest of the car is custom build with a Nascar like body made from carbon and a tube chassis.
As with all Porsches the engine is situated in the back, at least part of the engine, the actual engine is moved to the middle of the car for a better weight distribution. What you can see from the rear is the cooling system and the 6 speed manual gearbox. The engine is engineered and hand built by Jan Fatthauer himself to ensure it is build to his own specifications. You can choose to put a cover on the exposed parts of the engine to be more discrete, if that’s even possible when driving a car like this.
The rims are 19″ 3 piece custom forged. They measure 8,5×19 in the front and 11,5×19 in the back. Tires are special Continental V max to cope with the excessive speeds this car is capable off.
Here we have a better view from the rear. As mentioned before you can see the gearbox and the cooling system. This car has a 6 speed manual gearbox but you can also choose for sequential race gearbox if you really want to get the most out of the engine. The fans you see are there to suck the air through the oil coolers.
When we remove the main cover we can see a glimpse of the engine and are greeted by a 24 carat gold plated intake system. Jan Fatthauer chose for gold because of its excellent thermal properties. Thanks to titanium connecting rods, forged pistons and a whole lot of custom fabricated parts this car puts out an amazing 987bhp at 7.850rpm. I heard people say this car has even wheelspin when you’re in fifth gear, with 964Nm at 5.970rpm I have no doubt it will.
The suspension consists of a Mc Pherson system with double springs in the front. In the back we see inboard coil overs like we see in most supercars nowadays.
The customer can choose whatever interior he wants. There is absolutely no limit. In this demo car the seats are made by Recaro and throughout the interior the same color and stitching is applied. Notice the lexan window behind the seats, the engine is right behind it.
When choosing your interior you don’t have to think about a radio because you won’t be able to hear it.
The 9ff GT9 towards its top speed of 409km/h. I really wonder what it’s like to be driving with those enormous speeds. My fastest speed I have driven was 270km/h on the German autobahn.
What was your top speed?
