"With all these features the Accusump works great in a variety of applications. It protects against oil starvation in road racing where hard braking zones and long, high-g turns are the norm. In drag racing applications, it keeps oil pressure up when cars are decelerating at the end of their run. If you have a hot rod that sits for a long time between start-ups, the Accusump provides easy pre-oiling to protect against dry start damage. The Accusump extends the capabilities of a wet-sump oiling system and pushes back the point where a dry-sump system is necessary. Many of our customers see the Accusump as an alternative to converting to a dry-sump system. In most cases, the Accusump can bridge the gap between a wet-sump system's performance and what is needed to go racing. Due to the significant cost difference, stepping up to a dry-sump system is usually only done after significant alterations in the chassis and engine have improved the car's speed and handling to the point where the use of a wet-sump system is impractical."

Breathers
Mike Zeranski Jr.: "Under high cornering loads, oil can sometimes shoot out of the valve cover breathers. That's because when oil is hot, it can flow like water. The best defense against this is having the breathers positioned away from the direct flow of oil slosh. In circle track applications, we put the breathers on the left side of the motor and run a right-side valve cover with no vents. For applications were oil slosh moves in every direction, a baffle will help dampen this effect. A baffle can be installed directly into the valve cover, or a baffled breather grommet can be used. The best solution to prevent oil from reaching your breather is to run a line from the valve covers to a separate breather catch tank. In this situation, any oil that does make its way out of the valve cover will be collected in the tank. In some classes of racing, this type of setup is mandatory if the valve covers are going to be vented."

Windage
Thor Schroeder: "In recent years the term windage tray has been broadened to represent a couple different features. Often, the sheetmetal plate that goes over the opening of the sump, where it meets the body of the oil pan, is called a windage tray. This is actually the anti-slosh baffle, which is important in keeping the oil contained in the sump so that it doesn't get back into the rotating assembly. The windage tray itself is the screened or louvered piece that is either mounted directly to the main caps or in the oil pan itself, and it usually has an integrated crank scraper. At Moroso, our oil pan and windage tray designs live and die by our in-house dyno, outside testing by Moroso, our network of top engine builders, and the racers that test our products. We feel windage trays are important in a proper high-performance oiling system. The effects of a windage tray are more evident in some engines than in others. Static, short-stroke engines with big box oil pans that turn less than 5,500 rpm aren't going to be affected as much by a windage tray compared to an engine that is put through acceleration, deceleration, cornering loads, and quick up and down movements. Likewise, long-stroke engines with confined oil pans that turn over 5,500 rpm will experience more windage. We have seen and heard of windage trays freeing up to 5 percent more horsepower. Windage trays can also help control oil temperature and pressure by keeping oil off the crank so that it does not froth the oil, and put extra heat into the oil."
