advantages of DRY SUMP:
1. Engine always has a constant supply of oil. In wet pump oil splashes around and can incorporate some air. Air is not a good lubricant
2. The dry sump supplies from an oil tank and as a contrast is not affected by the vehicles acceleration and the tall height of the tank increases hydrostatc pressure helps force oil back into engine. Thus, it keeps always constant oil pressure.
3. Much more adjustable because of the oil pan
4. Reducing the height of the overall pumo the height of the engine is lowered. Since the engine comprises of almost 150 pounds of the 500 pound vehicle it might be very helpful.
5. The scavenge pump creates a suction in the engine case when they pump the oil to the external tank. This suction creates a negative pressure in the crankcase which has been shown to potentially increase power. This results because the pistons are no longer compressing any gases when they are moving downward. This decreases resistance and nominally increases power.
6. Also the oil is no longer open to the engines hot environment thus it can cool down a bit after passing through the hot engine
7. The dry sump allows oil capacity to decreased by 25% which offsets the additional weight of the dry sump
