A dry-sump system is a method to manage the lubricating motor oil in four-stroke and large two-stroke piston driven internal combustion engines. The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil pan) below the engine and a single pump.
When it comes to engine oiling systems they’re generally divided into two categories: dry sump and wet sump. With the exception of ultra-high performance sports car likely to see track use, most OEM oil systems are classified as wet sump.
The main purpose of the dry sump system is to contain all the stored oil in a separate tank, or reservoir. This reservoir is usually tall and round or narrow and specially designed with internal baffles, and an oil outlet (supply) at the very bottom for uninhibited oil supply.
A dry sump tends to hold more oil than a wet sump in an extra reservoir, so that means it works better for sustained cornering since it's harder to starve the engine of oil. It also allows...
At Dry Sump Solutions, we are dedicated to providing the best resources and products available to those wanting a reliable, race proven, oiling system for their race car.
The dry sump system is usually equipped with two oil pumps that are inserted on each cylinder bank and uses a separate oil reservoir that is located somewhere else in the engine bay. Unlike the old-fashioned wet sump system that uses the main sump and an oil pan to pump oil into the engine.
What is a Dry Sump Oil System? A dry sump system is a step up in complexity and efficiency from its wet sump counterpart. Unlike the wet sump, where oil remains in a pan beneath the engine, a dry sump system uses a separate external reservoir to store oil.
Yet dry sump oil systems free up horsepower and keep engines alive through grueling conditions better than a standard wet sump setup. To show how this seemingly magic setup works, Papadakis Racing created a video to show the ins and outs of a dry sump system.
At Dailey Engineering, we specialize in designing and manufacturing custom Dry Sump Oil Pans from billet 6061 T6 aluminum. Our “Signature Series” integral Dry Sump Oil Systems feature an innovative design where the oil pump bolts directly to the oil pan.
Dry Sump Oil Systems. A dry sump oil system is different in that it doesn’t have an oil reservoir in the oil pan under the motor. Instead the oil is sucked out of the motor by an oil pump in one or several locations. It is then pumped up to an oil reservoir.
