Porsche 911: The Porsche 911 Turbo TRC 91 by 9ff is the world's fastest cabrio

9ff is giving us some great Porsche news lately, and today is no exception. Please welcome the Porsche 911 Turbo TRC 91 which comes with 910 bhp in the coupe and 780 bhp for the cabrio! And it's nothing less than the world's fastest cabriolet.

Porsche specialist 9ff has dropped its potent 4.0L biturbo flat-six into the Porsche 911 Turbo Cabrio, and in doing so has created the world’s fastest convertible. Developing 780hp in the Cabrio, the modded 911 drop-top can reach a top speed of 381km/h.

To achieve this level of performance, engineers took the standard 3.6L biturbo motor from the regular 911 Turbo and added their own custom turbochargers, a sports air-filter, larger injectors, modified cylinder heads and a stainless steel exhaust system with special manifolds as well as high-performance catalysts, and finally, an extensive increase in engine displacement to the tune of 4.0L. To make sure everything is in check, all the modifications are controlled by means of a reprogrammed ECU.
