Techart GTstreet R is a meaty and vocal Porsche 911 Turbo image

Techart’s GTstreet R take on the Porsche 911 Turbo not only ramps power to 711 hp, but also utilizes a high-tech exhaust system that makes for a great soundtrack.

Because the aftermarket specialist probably likes to showcase its prowess, it has also opted for a fancy looking carbon fiber bodykit with active components in the front spoiler and a two-tiered rear wing. The replacement parts in carbon fiber are available for the front and rear bumpers, slotted front fenders, side skirts, and engine cover. And Techart is not only delivering visual goodness, it also has a mind for actual improvements. The front spoiler lip actively adjusts airflow into the radiators while the double-piece rear wing also raises and tilts up to 15 degrees in Performance mode for increased downforce. The result – 708 pounds of downforce at 186 miles per hour.

The 991.1 and 991.2 Porsche 911 Turbo starts the engine upgrade process with a pack that takes them to 632 horsepower (471 kilowatts) – but customers looking for the ultimate mod will have starting in 2017 an upgrade that takes the power to 711 hp (530 kW) and 679 pound-feet (920 Newton-meters) of torque. And we shouldn’t forget about the bespoke exhaust system with a continuously variable pneumatic valve that constantly works with the back pressure depending on engine load.
