9ff tunes Porsche GT2 over 650bhp
12 November 2008

German tuners 9ff have gone to work on the Porsche 911 GT2, squeezing 665bhp from its 3.6-litre flat six with a series of upgrades.

The firm has added a pair of V670 turbos, a new intake manifold and a new exhaust system with a two-stage boost valve.

The ECU has also been modified and the rev-limits been increased to 7200rpm.

The new engine set-up produces 665bhp and 590lb ft torque, compared with the standard GT2’s 522bhp and 500lb ft.

That means the 9ff GT2 sprints from 0 to 62mph in 3.6 seconds - the same as the standard car - but will reach 124mph from standstill in a crushing 9.6 seconds.

I can't help but think that Porsche have put a hell of a lot of expertise (variable vane geometry, re-cooled air to maximise density in the cylinders etc.) into their turbo installation, to ensure an impressively linear throttle response so important to a real-world driving rear wheel car of this nature, and then someone comes along, rips out their turbo installation and puts in a couple of bigger turbos. There goes the engineering integrity of the whole carefully engineered set-up, sacrificed for the false god of more horsepower.

I know 9ff are not amateurs, and I'm sure it will excite a motoring journalist for an afternoon's driving, but I'm not convinced this will be an improvement to live with in the real world.

Re-map, new pipes, sure. New turbos, no thanks

EVO (am I allowed to mention them here?) tested a couple of modified 911s a few months back. Despite each costing as much as a Carrera GT, neither one was as fast (let alone faster) than the standard GT2, and the Gemballa one was described as virtually undriveable. I also remember an extreme tuner test in an American magazine, in which half the cars developed faults (in one case terminal) during the test.

But what a great paint job! Total class.

    Diesel version of Skoda’s junior SUV is unobtrusive and undemanding, but we’d still go for the silkier petrol version of the Karoq

    A satisfying rework of the X3 that usefully improves its handling, cabin finish, space and connectivity to make this BMW a class front-runner again

    Off-road estate is now bigger, more spacious and available with torque-vectoring all-wheel drive, but is it enough to make its German rivals anxious?
