Let's hope you do not consider it for a sacrilege, but rather for a honour when we compare Porsche with Ferrari. Both companies were until recently ardent supporters of naturally aspirated engines, although they - Porsche since 1974 - had experience with turbochargers. One obviously did not want to miss the emotion by a high speed engine.
The question remains why both companies ultimately could not withstand the turbocharger. Case of the Porsche 911, clarification is not particularly difficult. Looking at the history of this, now 900,000 times built sports car, then the performance was always increased slightly upward, starting with 2 litres displacement and 96 kW (130 hp) up to now 272/309 kW (370 or 420 hp).
It was always a boxer six-cylinder, last with 3.8 litres cubic capacity. And here seems to be something like a limit. Eight cylinders seem impossible because of the position of the engine and larger single displacements jeopardize the concept of the relatively high number of revolutions. Seen so, the changeover of engines on turbocharger was predictably.
It will therefore go on with the performance, even without Matthias Müller as CEO of Porsche. It is interesting to see the future VW boss still in the old
function below in the video. But back to the two devices below right and left, the promise for the boxer engine reduced on three litres of cubic capacity, not only more performance, but also and especially a torque of now 450 or 500 Nm.
Although Porsche was so far the only company that has tried case of the petrol engine with VTG turbochargers, at a closer look at the right charger we find again here a wastegate. But besides that, there are more changes. The drive wheel for the exhaust camshaft adjacent directly to the right charger shows us the here now also built-in adjustability.
Above can be seen the nearly diesel-like, central arrangement of the direct injection. Although the steel piston is not an issue for petrol engines, but with the coating of the cylinders happens a lot. Newly for example, the clamping of cylinders in a frame, in order to avoid warping by the plasma coating.
You could ask of course, why videos with the engine sound of the new 911 become more frequent in Internet. This is the desperate search for the emotion of the old. Porsche offers to that a kind Manettino like Ferrari. Here you can adjust, in contrast to this not only each the complete setup, but also individual functions.
So all on 'normal' and upregulate only the engine sound. Whether it can then ties in on the good old days? Amazingly, the button for the drive mode at Porsche is at the same place as in Ferrari, at the already overloaded steering wheel. By the way, who still wants to order a naturally aspirated engine of Porsche, has to pick up the GT3, but pays then instead of barely 100,000 a little less than 140,000 euros. 09/15
