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 Features. For optimum oil pressure stability across the engines entire RPM range. Roots Scavenge Sections. Lower Center of Gravity. A thin oil pan design allows for a lower C.G. resulting in better handling characteristics. Windage Control.
TLDR; 1) The low profile pan in a dry sump system allows the engine to be lowered in the chassis for better handling. 2) No more oil pump starvation issues caused by forces acting on the oil during racing. 3) A properly designed dry sump system can improve engine performance.
In order to have a good understanding of the dry sump system, let's first examine the wet sump system. Wet sump oiling systems are used on 99% of all street cars. They utilize a conventional oil pan with dipstick, where the oil is stored and supplied to the oil pump.
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.
18 Απρ 2019 · Dry Sump Oil Pan and Pumps This particular pump has three scavenge sections, plus one pressure section. The pan actually has five pick-up points, but employing only three.
14 Νοε 2012 · A dry sump oil system uses a scavenge or suction pump to pull air and oil out of the oil pan. This keeps oil away from the crankshaft to reduce oil drag, and also pulls out most of the air to reduce windage and air drag (if the dry sump system has enough suction to produce vacuum in the crankcase).
