Re: [MBZ] dry sumps
> .What's a dry sump engine? No oil pan? Is this a bad thing?.. > A dry sump engine carries it's oil in a tank next to the engine. There is no oil pan but just a slight depression where the oil pickup for the scavenge pump is located. The main oil pump (likely in unit with the scavenge pump) draws it oil from the oil tank where the foam settles out and is filtered and then sent to the oil cooler and then to the oil galleries. The scavenge pump has vastly more pumping capacity because it's pumping mostly foam. Every aircoooled Porsche 911 engine ever built (since 1964) is a dry sump engine and carries on average of 11 quarts in the tank. Like the 6.9, this all allows the engine to be lower and lighter since it carries little oil itself.

Re: [MBZ] dry sumps
And not to forget, one of the big reasons for a dry sump, is no oil starvation when cornering through longer corners. Other none dry sump cars that are subjects to heavy g loads in corners, will often add baffles in the pan, to stop all the sloshing about, or the oil being thrown to one side in corners. A 911 will hold 2-3 quarts in the lower part of the engine, with about 7 or so quarts in the aux oil tank. Both are drained seperately in an old p car.

All flat six Porsches were dry sump engines (from 1965) for more oil capacity for cooling plus the engine could be lower to lower the center of gravity.
