9ff is the company behind a 409km/h 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 torender best performance on both the race track and also on publicroads. With its 670 hp strong “bolt on kit” and a running gear whichhas been perfected at the Nordschleife of the Nürburgring, the 9ff GT2impressively demonstrates that road capability and racing can be veryclose to each other without having to accept losses in comfort.
Extensive engine modifications lift the Porsche´s strength to 670 hpand max. 800 Nm (the serial model has 530 hp and 680 Nm). For thisreason, 9ff equips the therefore specifically developed V670 turbochargers with variable turbine geometry. The air inlet system with 9ffmanifolds was accordingly adapted to it. Also, the sport exhaust systemunderwent a drastic change: In-house racing headers, 100-cell sportcatalytic converters and titanium mufflers optimise the 9ff flapexhaust system whose sound can be adjusted to the concept of a race carfor every day use. The driver has the possibility to switch between aclose-to-production sportive sound or a powerful racing sound. Thepackage is amended by the adjustment of the control unit and itsincrease of a maximum number of 7,200 rpm.
The Dortmund-based engineers use a light single-mass sport flywheeland a clutch disk with organic coating. The special surface allows ajudder-free start in everyday use and therefore differs from othersport clutches in a positive way.
As far as the running gear is concerned, 9ff uses double chassissprings at the front- and also at the rear axles. The coilover kit hasespecially been optimised for the 9ff GT2 on the demandingNordschleife. With the 9ff GT2, the ambitious GT2 driver has theperfect arrangement of a race car for everyday use.
The driving performance of the 9ff GT2 is impressive. The rear wheeldriven two-seater sprints from 0 to a 100 km/h in 3.6 seconds. And from0 to 200 km/h, the GT2 only needs 9.8 seconds and therefore stays underthe mark of 10 seconds. Hereby, it is nearly two seconds faster thanits serial counterpart. And it only takes 25.8 seconds from 0 to 300km/h.
If 670 hp is not enough, then wait as 9ff is working on 710 hp-910 hp conversion as well.作者: my-bid 時間: 2008-11-8 12:17 PM
