Porsche 911 Turbo

Porsche 911 Turbo Accessories

The previous 911 Turbo was no slouch. When you thrust the pedal to the carpet in this new car, it surges forward effortlessly with little lag. The new Turbo's pleasantly muted engine noises are accompanied by the rising whoosh as the turbochargers breathe massive life into the car. Porsche's 2010 911 Turbo is equipped with the direct-injection flat-six engine recently debuted in the normally aspirated 911 Carrera range, but with twin turbochargers-quipped with variable-geometry vanes to optimize boost-which help increase output.

This new 3.8-liter turbo engine produces 500 hp and up to 516 lb-ft of torque when equipped with an overboost function included on Sport Chrono models. Regular models have 480 lb-ft between 1950 and 5000 rpm at the usual 0.8-bar maximum boost ceiling.

The engine received numerous upgrades to deliver the increased output, among them a compression ratio increased from 9.0 to 9.8:1, a higher pressure fuel pump, a low back-pressure exhaust system and two additional oil pumps (for the turbochargers, there are already four in the integral dry-sump system). Active engine mounts using magneto-rheological fluid are included with the optional Sport Chrono package ($3470), and the dual-clutch, seven-speed PDK transmission ($4550) is available for the first time on the Turbo.
