9ff is the company behind a 409 km/h (253 mph) GT9, that is based on the GT3. Their new project is called 9ff GT2 670.

According to 9ff the objective was to build a GT2 which is able to render best performance on both the race track and also on public roads. With its 670 hp strong “bolt on kit” and a running gear which has been perfected at the Nordschleife of the Nürburgring, the 9ff GT2 impressively demonstrates that road capability and racing can be very close to each other without having to accept losses in comfort.

Extensive engine modifications lift the Porsche´s strength to 670 hp and max. 800 Nm (the serial model has 530 hp and 680 Nm). For this reason, 9ff equips the therefore specifically developed V670 turbo chargers with variable turbine geometry. The air inlet system with 9ff manifolds was accordingly adapted to it. Also, the sport exhaust system underwent a drastic change: In-house racing headers, 100-cell sport catalytic converters and titanium mufflers optimise the 9ff flap exhaust system whose sound can be adjusted to the concept of a race car for every day use. The driver has the possibility to switch between a close-to-production sportive sound or a powerful racing sound. The package is amended by the adjustment of the control unit and its increase of a maximum number of 7,200 rpm.

The Dortmund-based engineers use a light single-mass sport flywheel and a clutch disk with organic coating. The special surface allows a judder-free start in everyday use and therefore differs from other sport clutches in a positive way.

As far as the running gear is concerned, 9ff uses double chassis springs at the front- and also at the rear axles. The coilover kit has especially been optimised for the 9ff GT2 on the demanding Nordschleife. With the 9ff GT2, the ambitious GT2 driver has the perfect arrangement of a race car for everyday use.

The driving performance of the 9ff GT2 is impressive. The rear wheel driven two-seater sprints from 0 to a 100 km/h in 3.6 seconds. And from 0 to 200 km/h, the GT2 only needs 9.8 seconds and therefore stays under the mark of 10 seconds. Hereby, it is nearly two seconds faster than its serial counterpart. And it only takes 25.8 seconds from 0 to 300 km/h.

If 670 hp is not enough, then wait as 9ff is working on 710 hp-910 hp conversion as well.
