An American tuning firm from the heart of NASCAR country has upgraded output in a 911 Turbo Cabrio to 660 horsepower. With the launch of the all-new 991 generation 911 Turbo set likely to take place next September at the Frankfurt Auto Show, aftermarket tuning firms are still making power and handling modifications to the outgoing generation, the 997 911 Turbo, which remains on sale until the new one arrives in showrooms. One of those firms is Charlotte, North Carolina, based GMP Performance who has just completed some custom work for a client on a one-of-a-kind 997 Turbo Cabrio.
