If you are actively racing then you will notice that from time to time your oil pump will not have enough oil, because it is going in all directions when you are braking, accelerating and cornering. This can happen with cars that do not have that much power. for example with autox cars. It is a logic thought to check how to make sure this does not happen.
Baffled sump
This one is most known. The principle is simple. Put some sheets in your carter that make sure the oil stays near the oil pump. More complex systems have trap soors that make sure the oil reaches the pump but cant escape anymore. This way your pump is ensured of an adequate supply.
High capacity sump
Another method is increasing your carter by welding an extra resevoir to it. The thought behind this is that when there is more oil in the system you can supply it better. This might be true in theory, but practically it has some problems. Most of the time this are space problems when you want to increase the depth or width of your simp. Also the pump usually gets the oil from the lowest point so lovering it even more might have some negative effects for the supply.
Dry sump
As you might have read here is that one of the low profile racers has a dry sump system. As we have promised back them we would continue about it this time. A dry sump is a cover instead of a sump. At the bottom of this cover there are some oil lines that feed the oil to a separate resevoir and an improved oil pump. This pump will not be the limiting factor in oil pick up and can be made sure to have oil all the time. You can have it mounted to the crankshaft as a regular oil pump, but you can also choose for an electric one. If you so that you can make sure to have oil running through the block before the engine starts. Another advantage is that you can put heater elements in the oil resevoir. this way you can have oil of the right heat running through the block before the engine even has started. Also you can place the engine lower as a dry sump takes less place than a regular sump. The biggest downside is the price, which is usually several thousands for a dry sump kit.
