Breaking the 400 km/h (249mph) barrier is no simple task and Porsche specialist tuner, 9ff, from Papenburg Germany have done so with honour. However, despite celebrated claims of breaking the world-record for road-going vehicles at 409 km/h, our research tells us this ain't so.
Regardless, after a couple years of GT9 coverage, 9ff has finally revealed all of the sumptuous technical details, production and pricing of its 400 km/h projectile.
Starting with its powerplant, the 996 Turbo sourced motor has been bored out to 4.0-liters which includes reworked turbos, dry sump oil lubrication system, titanium connecting rods, forged pistons and a 24 carat hard gold plated induction plate. The result is 987 PS / 726 kW at 7,850 rpm. The maximum torque of 964 Nm is reached at 5,970 rpm. Transmission is race prepared sequential unit.
The suspension is electronically adjustable aluminium shock absorbers in connection with double spring rate McPherson front axle and horizontal push-rods at the 5-link rear axle. Brakes disks are ceramic sandwiched by front 6- and rear 4-piston calipers. Special brake pads and an individually engineered race-ABS complete the system.
Lastly, the body is a Frankenstein of sorts, taking the front end of the Porsche GT3 model with a tubular steel-grid and developed a chassis made of very strong yet lightweight carbon and Kevlar fibre.
Vital to reaching speeds over 400 km/h, the under-body casing integrates a wind diffuser which generates additional downforce and stability at high speeds. Additionally, the low height of only 1,180 mm presents an increased aerodynamic profile while giving striking exotic look.
9ff will produce only 20 units of the GT9 for the price of 498,000 Euros.
409 km/h – The automobile refiner 9ff breaks the world-record for road-going vehicles
ATP test centre Papenburg, April 2008
Graduate engineer Jan Fatthauer, creator and also test pilot of the 9ff proprietary development GT9, accelerates and speeds up from the full banked corner on the Papenburg oval course. Accompanied by a sound spectacle of automobile top class, the 964 Newton metres torque push down on the asphalt and vehemently thrust the car forward. At the end of the four kilometre long straight, the display of the satellite-supported time measurement shows an incredible 409 km/h. With such a result, the 9ff GT9 does not only becomes a member in the elitist 400km/h-Club, no, it even takes the first place and also breaks the new Vmax world record for road-going vehicles.
The source of power
Even as impressive as the maximum speed are the acceleration values of the rear-wheel driven car. It accelerates to 100 km/h in only 3.4 seconds, to 200km/h in only 8.2 seconds and the digital display of the instrument panel shows the 300 km/h in unbelievable 16.4 seconds. The source of power for this overwhelming power is a modified motor from the Porsche 996 Turbo. The water-cooled 6-cylinder horizontally opposed engine with 4 litres cubic capacity and dry sump is equipped with two exhaust twin turbo chargers, titanium connecting rods, forged pistons and a 24 carat hard gold plated induction plate. Thereby, the high-tech aggregate achieves sensational 987 PS / 726 kW at 7,850 r.p.m. The maximum torque of 964 Nm is reached at 5,970 r.p.m.
Custom-made drive technology
9ff offers an alternative to the stationary rear 6-speed transmission, a sequential race transmission. For both models, the transmissions are assembled according to the customer preference.
Guarantee for driving pleasure, comfort and safety
Of course, when developing the 9ff GT9, we put the highest emphasis on driving dynamics and safety. The chassis was equipped with state of the art technology components from motor sports. Electronically adjustable aluminium shock absorbers in connection with double springs at the McPherson front axle and horizontal push-rods at the 5-steering rear axle guarantee an ideal road grip. 9ff uses tyres by its technology partner Continental which ensure a perfect grip and traction. Selected Continental Vmax tyres in connection with ultra-light three-part forged wheels are approved up to a speed of 410 km/h and are therefore perfect for the requirements of such a high-speed car. 9ff uses the wheel-tyre combination with the dimensions 8.5 x 19 with 235/ZR 19 at the front and 11.5 x 19 with 325/30 ZR 19 at the back.
An opulently dimensioned sport brake system provides excellent deceleration values. Ceramic brake discs measuring 380 mm (front) and 350 mm (back) are sandwiched by the front 6- and rear 4-piston system. Special brake pads and an individually engineered race-ABS complete the system.
A breathtaking styling is the result of design and function
A perfect surface quality and a custom-made finish are the hallmarks of the lift-reducing GT9 car design. No dazzler, but a conclusive concept full of technical finesse and dressed in a breathtaking silhouette. For maximum crash safety, 9ff combines the Porsche GT3 front vehicle with a tubular steel-grid and developed a chassis made of very strong carbon- and Kevlar fibre. The compact under-body casing with its integrated rear diffuser generates additional output and renders stability at high speeds. The main feature of the 9ff GT9 is its low height of only 1,180 mm which underlines the striking racy impression. Moreover, its small frontal area is an important criterion for reaching speeds over 400 km/h.
Engineered design without limits
What ever makes your heart beats faster, we have it. Embroidered car mats, full-leather interior, everything produced with skilled craftsmanship. Whether you like it noble or sportive - 9ff offers has everything for any taste.
The 9ff Fahrzeugtechnik GmbH produces a limited edition of 20 GT9 cars at the company location in Dortmund. The super race car by this specialist manufacturer for tuned Porsche cars is offered from 498,000 euros.

This is what aftermarket tuning firms are all about. What a brilliant machine!
induction plate, not 100% sure, but I believe it is the part of the car that brings the 70 or so volts off the alternator down to 12 volts by converting the excess energy into heat which then radiates away from the car. Pure gold is the universes best conductor, so to make the heat radiating part of it gold would enhance the thermal rate of heat dissipation, this allows you to use a smaller lighter weight heat sink (at least that is my somewhat educated guess)
wonder what this beast does on the Nurburgring, i'm sure it will make a hell of a time, not like others +400km:h cars, that are only fast on a straight line.
it's fast, it's high tech and it's ugly like hell. i think i'd feel vrey silly driving one of the fastest cars, and the car is looking like .. i really can't find the word. it's the same story like with the enzo. the best ferarri but... looks like a rats ass. if i pay that amount of money i wanna look good in it too.
