Vacuum Pump: Description and Operation

Vacuum Pump

Similar to the current 911 generation, the new 911 Turbo also has a mechanically driven vacuum pump that uses rotary vane technology. This replaces the conventional vacuum amplifier to provide the vacuum for the brake booster and for activating various switching valves. It is located on the cylinder head of cylinder bank 1-3 and is driven by the corresponding exhaust camshaft.
