As the flagship model of 9 1 1 automobile series, 9 1 1? Turbocharged? S has no less fighting power than GT series, but also takes into account the comfort of road driving. It can not only get off the track on weekends, but also commute on weekdays. It's an ideal car. And Turbo has always been the technical pioneer of 9 1 1 car series. Turbo is to 9 1 1 what 9 1 1 means to Porsche.
As early as 1905, Alfred, chief engineer of Sulzer Brothers R&D Company? Dr Buechi put forward the concept of turbocharging and applied for a patent in Germany in June of that year. Subsequently, the first world war officially put turbocharging technology on the historical stage. However, due to many technical problems, it was not until the 1960s that turbocharging was applied to automobiles.
In 1970s, due to the oil crisis, turbocharging technology entered a stage of rapid development, especially in the field of racing. 1973, turbocharging technology passed the test of motor racing with excellent results on Porsche 9 17/30. The maximum power of this convertible two-seater car reached an astonishing 809kW, which left all competitors in the CanAm series in North America behind.
For Porsche 9 1 1, the engine compartment is not very spacious due to the rear-mounted rear-drive layout, and the engine compartment of competitors can accommodate V8, V 10 and other large-displacement engines, so turbocharging technology has become the best choice for Porsche to improve the performance of 9 1 1 vehicle.
At that time, the biggest problem of this technology was that the powerful power generated by the turbocharger was usually accompanied by the greatly shortened engine life, extremely high throttle sensitivity and more willful handling performance. Therefore, most people think that turbocharged engines cannot be "tamed".
Porsche engineers control the boost pressure through the wastegate valve, which overcomes the shortcomings of turbocharged engines, such as power and acceleration at low engine speed. Until then, this method was used in the competition. This complex control system allows the turbocharger to be designed to build up pressure even at low engine speeds, thus simultaneously generating greater torque.
9 1 1? Turbocharged? 3.0(930)
1974 At the Paris Motor Show, with Porsche's brand-new high-performance sports car 9 1 1? Turbocharged? With the launch of 3.0(930), turbocharging technology has been formally incorporated into the Porsche production car system. Maximum power 19 1kW, maximum speed 250km/h, 9 1 1? Turbocharged? 3.0 was the fastest road sports car in Germany for a long time.

Turbocharged? 3.3 It was almost invincible at that time.
The 930 series has been mass-produced to 1988 with little change, which has laid a solid foundation for the success of turbocharged models. The production of the second-generation 9 1 1 officially ended in 1989, and these sports cars code-named 930 are still legends. Because the 930 is too big, many people like to regard it as the code of the second generation 9 1 1 instead of the G-Model.
9 1 1? Turbocharging (964)
1988, the third generation of Porsche 9 1 1(964) came out, and then 199 1965438 9 1?

In 2004, the sixth generation 9 1 1(997) came out, and in February 2006, 9 1 1? Turbo(997) shocked the whole world, because it was equipped with a turbocharger with a variable geometry turbine (VTG), which means that the guide vanes of the turbine can have multiple angles of attack. When the engine speed is low, the angle of the blade relative to the exhaust gas flow is small, so the response speed is faster.
Although this technology has been implemented in diesel engines, 9 1 1? The variable geometry turbine developed by turbocharged gasoline engine must be started from scratch. Compared with diesel engine, higher working temperature means that many new materials from aerospace industry are needed. Therefore, Porsche became the first automobile manufacturer in the world to combine gasoline models with variable geometry turbine technology (VTG).
