Mike Zeranski Jr.: "Windage trays work great in providing a few more easy horsepower when installing a high-performance oil pan. Canton designs its trays to complement our pans and the engines they are designed for. They help pull away oil spinning around the rotating assembly and keep oil in the pan from splashing up into the crank. In both cases they help free up the rotating assembly from the drag created by oil mist. Whether or not you think the hp gain is worth it depends on what you are trying to accomplish. When you're looking to squeeze every bit of horsepower from an engine, a windage tray is an important piece of the puzzle. They can often provide that little extra that is needed for an engine builder to reach a certain horsepower goal on the dyno. Of course, for street cars and other more recreational applications, the extra horsepower that the windage tray provides will not be noticed from behind the wheel."

Dry-Sump Oiling
Thor Schroeder: "A dry-sump oiling system consists of the dry-sump pump itself, which can have anywhere from one to six stages. The stage designation refers to how many scavenge and pressure sections the pump has. A single-stage oil pump has one scavenge stage and no pressure stages. The oil pan would have one externally exiting oil pump pickup and the oil pump would be outside of the oil pan and driven off of the crank. Since there is no internal oil pump, a full-length windage tray can be used to free up horsepower, and the oil pump can be easily adjusted outside of the engine. The oil is stored inside the oil pan like a wet-sump oiling system. "A four-stage oiling system has three oil pump pickups in the oil pan itself. Each one of these pickups are plumbed to the three scavenge sections of the oil pump. In this type of oiling system, a full-length windage tray can be used inside of the oil pan, and the oil can be stored outside of the oil pan in a baffled dry sump tank. They're popular in racing classes that allow them; especially where low chassis height is important for good handling. Horsepower gain is maximized because there is virtually no oil in the pan and no internal pump, allowing the windage tray or screen to run the full length of the pan. Other advantages of a dry-sump system include a remotely mounted oil tank for increased capacity, the ability to easily add remote oil coolers, more consistent oil pressure, adjustable oil pressure, improved scavenging, and increased ring seal due to greater oil pan vacuum."

Oil Temp
Thor Schroeder: "Oil longevity decreases exponentially as temperature increases, but oil doesn't flow freely when it's too cold. It's a balancing act, but there isn't an easy answer when it comes to the ideal temperature range oil should operate at. Optimal oil operating temperature can be different for different engines depending on engine tolerances and the type of oil used. Automakers often make engines run on the hot side for emissions at the expense of other factors. Hotter oil produces lower oil pressure and lower viscosity. Optimal oil operating temperature is also dependent upon water temperatures. At lower temperature levels, in the low 200-degree range, we have seen a 10-degree difference in oil temperature make 2 percent more horsepower on our dyno."

Mike Zeranski Jr.: "We recommend an oil operating temperature of at least 215 degrees, and build our oil cooler thermostats to operate above that temperature. By keeping the oil temperature above the boiling point of water condensation that may accumulate in the pan, it ensures that the water in the oil will evaporate out. Water significantly reduces oil life, and oil temps that are too cool will not allow the water to evaporate, especially if a motor is run for only short periods of time. Also, at this temperature the oil should achieve its intended viscosity and perform as designed, flowing and lubricating the engine most efficiently."
