Moroso: About Oil Pans|
Dick Moroso first pioneered the deep sump oil pan 30 years ago. He discovered that keeping oil away from the crankshaft produced more power. By preventing the crankshaft from "sloshing" in oil, frictional losses known as "windage" are greatly reduced. In fact, Moroso was the first to use an engine dynamometer to test oil pan designs. We even developed see-through pans and used video cameras and strobe lights to track this oil system phenomena. These studies allowed us to design pans that would remove oil from the crank quickly and efficiently, and direct it towards the oil pump pickup. Uni-directional windage tray screens, block-level scrapers and passenger-side kickouts were the result of our extensive research and development program.
Our highly-qualified engineering staff continues to work very closely with the country’s top engine builders and racers to squeeze every drop of horsepower from our pans. At Moroso, the commitment to innovation never ends!
Engineered As A Fully
All Moroso oil pans and oiling components are engineered to be fully compatible with one another. This allows engine builders to select the best combination of equipment to suit their particular needs. It also eliminates the problems that often occur when using components from different manufacturers.
|Moroso offers a wide variety of oiling system accessories including oil pumps, pickups, windage trays and screens, crankshaft scrapers, tanks, breathers, fittings, filters, drive kits, oil pre-heaters, and accumulators. Each is designed, developed and tested to work together as an integrated system with our oil pans. And each is built with the quality that you’ve come to expect from Moroso.|
Built With Quality
Moroso oil pans are manufactured from the finest steel and aluminum available. Each pan is jig welded and block fit to minimize warpage and insure proper fit and sealing. Before leaving our factory, each and every pan is leak tested for the ultimate in quality control. Superior engineering, choice materials, excellent manufacturing and painstaking quality control -- these are the ingredients that go into every Moroso oil pan.
Your satisfaction is our highest priority! If you should encounter a problem, we want to know about it. Call us immediately at (203) 458-0542.
As another example of our commitment to racing and our loyal customers, Moroso is a major contingency sponsor with several sanctioning bodies including NHRA, IHRA, Nascar and NSCA. Moroso posts thousands of dollars annually in contingency awards that racers collect when they win with selected Moroso products and proudly display our decal.

|Wet Sump vs. Dry Sump Oiling Systems|
The use of a wet or dry sump oiling system is often determined by the level of competition and the racer’s budget. A wet sump system is based on the original equipment oiling system, and can be enhanced with certain components to improve oil control and increase power. A dry sump system is designed for the top levels of racing where maximum power and oil control are absolutely essential.
|Typical Wet Sump System|
In a typical Wet Sump system, oil is stored in the bottom of the pan and distributed throughout the engine by an internally-mounted pump. An oil pump pickup, mounted to the pump, extends to within a quarter-inch of the pan’s bottom to "pickup" the oil.
Although a wet sump system is essentially the same system used in production cars, it can be enhanced significantly with components that improve oil control and increase power. For performance street and racing applications, these components include high-capacity pans, extended oil pump pickups, racing oil pumps, windage trays, oil control kits, racing oil filters and other components. In some racing applications an external oil pump is used, allowing the windage tray or screen to run the pan’s full length.
Moroso Wet Sump Oiling System components are race proven, designed to keep the engine properly supplied with oil during the most demanding conditions.
|Oil Pan Capacities|
Capacities listed for Moroso Wet Sump Oil Pans include the capacity of the pan only, measured at or below the normal fill mark on a stock dipstick. Additional oil must be added to compensate for filters, coolers, tanks, etc.
|Typical Dry Sump System|
|Unlike a wet sump system where oil is stored in the pan, a Dry Sump Oiling system stores oil in a separate tank -- leaving the pan essentially "dry." An externally-mounted pump, generally with three or four stages, is used to "scavenge" or remove oil from the pan, deliver it to the storage tank, and send it back through the engine. In a typical setup, all but one of the stages is used to scavenge oil from the pan. A single pressure stage is normally used to return oil from the tank to the engine.|
The primary advantage of a dry sump system is its ability to make more power. With very little oil in the pan, the rotating assembly is not burdened with the weight of excess oil (a phenomenon commonly referred to as "windage"). And because there is no internal pump, the windage tray or screen which serves to isolate sump oil from the rotating assembly, is allowed to run the full length of the pan. Keeping the rotating assembly free of windage allows it to spin freely and make
|more power. In addition, the extra crankcase vacuum created by the dry sump pump helps to improve ring seal for additional power gain.|
Other advantages of a dry sump system include increased oil capacity, more consistent oil pressure, the ability to easily add remote coolers, and adjustable oil pressure. And because the pan doesn’t store oil, it can be relatively shallow in depth to allow lower engine placement for improved weight distribution and handling.
Moroso manufactures a full range of Dry Sump Oiling System components, all of which are engineered to be fully compatible with one another. This allows the engine builder to select the best combination of equipment and avoid the costly problems that often occur when "mixing and matching" components from various manufacturers.
|Note: Oil pan rules vary from track to track. Check with your race track and/or sanctioning body before selecting your Moroso Oil Pan.|
