1.1 General

The engine in the new 911 GT3 has been completely redesigned, adopting classic 911 GT3 components, such as dry sump lubrication with a separate engine oil tank, high engine speed concept, titanium connecting rods and sports exhaust system, as well as including totally new components, such as valve lever control for the valves.

In addition, the new 911 GT3 engine also features direct fuel injection (DFI), an electronic demand-controlled oil pump and an enhanced high engine speed concept. As a result, the engine delivers a maximum power output of 475 hp (350 kW) and power output per liter of 125 hp/l with a displacement of 3.8 liters.

In addition to the mechanical and thermodynamic enhancements, it was also possible to significantly reduce the engine weight compared to the engine in the previous model. The weight reduction of approximately 55 lbs. (25 kg) was primarily achieved by using a new lightweight cylinder head, a new oil pan with integrated oil pump module, a smaller engine oil tank, a plastic intake manifold and aluminum camshaft controllers.
