1.1 General information

The engine of the new 911 GT3 Cup (991 II) is an enhancement of the unit in the road-
approved 911 GT3 RS with displacement of 3,996 cc. New features compared with
the previous Cup engine are the direct fuel injection, camshaft control for the intake
and exhaust valves, and rigidly mounted valve levers for valve actuation. The oil supply
for the connecting-rod bearings is ensured by the central oil supply to the crankshaft.
Also new is the demand-controlled oil pump with integrated centrifuge for oil
defoaming. The engine features dry-sump lubrication with an oil tank mounted on the
engine side. The oil is cooled by an oil/water heat exchanger integrated into the cooling
system.
The Bosch Motronic MS 4.6 NG control unit is used for engine control.
