Even though the freshly unveiled Porsche 911 Turbo S leaves the Stuttgart factory with more ponies than a horse farm (530, to be precise), it's still not enough to satisfy German tuning firm, Techart.
Its team of engineers crafted a new power kit that increases the flat-six engine's output by 90HP and 120Nm for a total of 620-horsepower and 820Nm (604.8 lb-ft) of peak torque. The boost is achieved through a reprogrammed ECU, a free-flow air filter, a new manifold and a sport exhaust system.
