9ff GTurbo – Click above for high-res image gallery

There's a fine line between a sportscar and a supercar. Porsche is one of the few automakers that straddles the line, but an elite cadre of tuners seem to take pleasure in laying down strips of burnt rubber to blur it beyond recognition. Names like Gemballa and Ruf come to mind, but 9ff has emerged as the new power player, in one sense or another. And the German tuning house has just let its latest out into the world.

Called the GTurbo, what we're looking at essentially is a tuning program for the 911 GT3 and its even more extreme brother, the GT3 RS. Bolting on a pair of turbochargers, 9ff can take a GT3 up to 750, 850 or even 1,000 horsepower. That's Veyron-league power, only without the all-wheel drive, the ground-grabbing track and the aero designed to go with it. Fortunately, 9ff has part of the answer in the form of a corresponding kit, including new bumpers front and rear, side skirts, and new quarter panels, with extra vents all around to keep the intercooler breathing and the air flowing. In full-fat 1,000hp spec, 9ff says its GTurbo will hit 100 kilometers per hour (62 miles per hour) in a scant 2.9 seconds and, theoretically at least, hit 392 kilometers per hour (243 miles per hour) flat out – which may seem like a heck of a claim until you realize that one of their own modded 1,000hp 911 Turbo hit just that at the Papenburg test track.

The aero kit sells for 8,900 euros (~$12k), with five-spoke 19-inch rims for 4,980 euros (~$7k) and a specially-designed set of central-locking wheels for 5,950 euros (~$8k), all before taxes and painting. We're afraid to ask how much the turbos cost, though. Details in the press release after the jump and photos in the gallery below.

How to make a supersports-car out of a sports car?

9ff demonstrates it with its new 9ff GTurbo850. The basis car is nothing less than a Porsche 997 GT or Porsche 997 GT3 RS. Vehicles, which already have an engine power of 435 HP with the 997 GT3 and 450 HP in case of the 997 GT3 RS. The concept of these cars follows the requirements of motor sport.

The requirements and expectations of a tuner are accordingly high. 9ff has accepted this challenge and put a Bi-Turbo conversion to the engine. The result is a maximum power from up to 1000 HP. Only the highest-quality materials are used. For example titanium connecting rods an extra strong forged pistons.

However, only the many years of experience and competence from 9ff in the areas of development, construction and set-up of high-end engines make this engine power possible. As a result 9ff offers the following conversions:

  • 9ff GTurbo750: 750HP / 850 NM torque
  • 9ff GTurbo850: 850HP / 910 NM torque
  • 9ff GTurbo1000: 1000HP / 940 NM torque

The fact that these vehicles belong to the super sports cars is also demonstrated by their performance data:

In addition, top speeds according to gear translation up to 392 km/h are facts which make a car to a real super sports car.

In the car body the following adaptations were carried out:

For a better cooling effect of the intercooler, the rear fenders are equipped with air intakes. 9ff put air outlets in the front fender in order to reduce the pressure in the wheel wells at high speed. But merely engine power is not enough for 9ff. 9ff presents in the 9ff GTurbo850 also for the first time, the new aerodynamics kit in 9ff GTurbo design. The kit consists of a front apron with LED indicators, side skirts and a rear apron. The rear apron is available in two variations. Once as a variation for the middle exhaust system of the GT3, GT3RS and 9ff Speed9. And the second variation for left / right exhausts systems for all other 997. Naturally we also offer a solution, for the conversion from the side exhaust system to the left / right exhaust system.

The price of the aerodynamic kit 9ff GTurbo design is Euro 8.900,00 (tax, mounting and painting excluded)

Another highlight is the new light alloy wheel in sporty 5 double spokes design. The 9ff GTurbo design rims comes in the dimension 8,5x19" / 11x19" and fits with the regular tires. Price for a set is Euro 4.980,00 (tax, painting excluded).

As another option 9ff offers the 9ff GTurbo design rims with a central lock system. Price for a set of the 9ff GTurbo design rims with central lock is Euro 5.950,00 (tax, painting excluded).
