In a dry-sump system, the oil still falls to the base of the engine, but into a much shallower sump, where one or more scavenge pumps draw it away and transfer it to a (usually external) reservoir, where it is both cooled and de-aerated before being recirculated through the engine by a pressure pump. The sump in a dry-sump system is not ...
LS3 engines found in manual transmission-equipped C6 Corvette Grand Sport models also received a dry sump oiling system similar to the one fitted to LS7-equipped Corvettes. From April 2008, Australian performance car manufacturer HSV adopted the LS3 as its standard V8 throughout the range, replacing the 6.0-liter LS2.
Oil delivery 9 litres (2.4 US gal; 2.0 imp gal) oil, dry-sump, via two-stage controlled suction pump (250 litres (66 US gal; 55 imp gal) /min), a pressure pump and a 12 litres (3.2 US gal; 2.6 imp gal) external oil tank; Oil cooling External engine oil cooler in the front
Until the introduction of LT6 engine in October 2021, LS7 was the most powerful production naturally aspirated engine made by General Motors. In addition to the larger displacement engine, the Corvette Z06 has a dry sump oiling system, and connecting rods made out of titanium alloy.
Dry sump engines in some drag racing cars use scavenging pumps to extract oil and gases from the crankcase. [18] A separator removes the oil, then the gases are fed into the exhaust system via a venturi tube. [citation needed]. This system maintains a small amount of vacuum in the crankcase and minimises the amount of oil in the engine that ...
During the development process for the 997.2 generation of 911 engines, Porsche built out this engine oil sump rig to test its new integrated sump system. It't a crazy bit of equipment to watch in ...
The new model was an LS3 equipped Z06 with a steel frame instead of aluminum. It retained many of the features of the Z06 including a wide body with 18x9.5 and 19x12 inch wheels, dry-sump oiling (manual transmission coupes only), 6-piston 14-inch front brakes and 4-piston rear, and improved suspension.

Later systems collect oil in a sump, from where it can be collected and pumped around the engine again, usually after rudimentary filtering. This system has long been the norm for larger internal combustion engines. A pumped oil system can use higher oil pressures and so makes the use of hydrostatic bearings easier. These gave a greater load ...
