In terms of factory-built near-race cars, the Porsche GT2 is a legendary beast - its current generation generates 530hp (395kW) in stock form, and its raw, unbridled character is famous (or infamous) thanks to the rear-drive, rear-engine configuration. The tuners at 9ff decided it just wasn't quite enough, however, and decided to fit a special variable turbine geometry turbocharger and extensive engine mods to bring power up to a ZR-1 beating 670hp (500kW).

In fact, that 670hp figure beats even the Mercedes SL65 AMG Black Series in terms of overall power, and the GT2 is considerably lighter. Acceleration in the 9ff GT2 is brutal: 3.6 seconds to 62mph (100km/h), 9.8 seconds to 124mph (200km/h) and just 25.8 seconds to 186mph (300km/h) - faster than both the Ferrari Enzo and the Porsche Carrera GT.

The V670 turbochargers are only part of the story, but they are an imporant part. A custom 9ff air intake manifold helps the turbos breathe, while in-house designed and built racing headers and exhaust system helps flow through the engine. A custom valve on the exhaust allows the driver to choose from a tamer near-stock sound level or a wide-open race car sound for track use. An ECU tune and raised rev limiter to 7,200rpm finish the engine modifications.

A lightweight single-mass flywheel and an organic-coated racing clutch combine easy driveability with better performance, and the coil-over suspension has been optimized for lap times at the Nordschleife. That track's notoriously bumpy and uneven surface has led to a near-race-level performance car with characteristics that 9ff claims make it comfortable to drive daily - provided the accelerator is used gently.
