PORSCHE TUNING SPECIALIST 9ff claims it has built the world's fastest road-going Porsche.

The record-clinching car was built around a regular 997 Turbo, and recently managed to hit a top speed of 391.7km/h around Germany's Papenburg high-speed ring.

Besides being able to achieve a top speed approaching that of a Bugatti Veyron, the 9ff TR 1000 is also able to sprint from zero to 100km/h in 3.2 seconds, accelerate from 100km/h to 200km/h in just 4.8 seconds and go from 200km/h to 300km/h in a mind-bending 8.0 seconds.


A heavily modified version of the Turbo's 3.6 litre flat six delivers a monstrous 735kW and an astonishing 1040Nm of torque.

A pair of bigger turbochargers, new camshafts, larger intercoolers, a high-flow exhaust and revised ECU tuning deliver the extra power, while heavily reinforced internals such as titanium conrods and a titanium crank help the engine cope with the stress.

9ff believes the car can push through the 400km/h barrier with some added aerodynamic tweaks, and a beefed-up braking system and sport tuned suspension will eventually be fitted to the car.

Want to do the same to your own 997 Turbo? 9ff says the conversion has so far cost €130,000 (AU$208,600) - almost two-thirds the retail price of the base car itself.
