What are the internals of a Porsche M97?
Porsche M97 timing internals. The M97 engine uses a mechanical vacuum pump instead of a conventional sucking jet pump to provide vacuum for the brake booster. This design enables a consistent level of vacuum supply in difficult conditions such as high altitude driving or driving on a track. Figure 5. M97 mechanical vacuum pump.
What kind of vacuum pump does Porsche M97 use?
The M97 engine uses a mechanical vacuum pump instead of a conventional sucking jet pump to provide vacuum for the brake booster. This design enables a consistent level of vacuum supply in difficult conditions such as high altitude driving or driving on a track. Figure 5. M97 mechanical vacuum pump.
What causes smoke at the start of a Porsche 911?
The smoke at startup can also be caused by a air oil separator (AOS) that is going bad but not completely failed yet. The M96 and M97 engines are famed for cylinder scoring – deep gauges in the cylinder liner, usually associated with a knocking noise and eventually catastrophic engine failure.
Why does the M97 engine have an intake?
That being said, there is still a good envelope in which M97 owners can enjoy better power delivery and performance. Intakes allow the engine to bring in more air. When mixed with the appropriate amount of fuel, this can create more power. The key to improving the intake on the M97 is enhancing the flow characteristics and air velocity.

When did Porsche start using the M96 engine?
In 1997, the M96 was then placed for the first time in the 911 as a 3.4L flat 6 making around 296 BHP. It would later get a displacement increase to 3.6L which would be the biggest production version of the engine to come from Porsche. This engine would also go on to power the next generation of 911, the 997, as the base Carrera’s power plant.
