Here is a break down of a Dry sump vs Wet sump, for some of the new guys who may know what it is but not really. (I got this out of Canton Racing Products Catalog)
"In a nutshell, the difference between a wet sump system and a dry sump system is where the oil is stored. In a wet sump system the oil is stored in the oil pan itself. The oil is pumped to your engine using an engine mounted oil pump usually in the oil pan. A dry sump system stores the oil in a remotely mounted tank. The oil is scavenged or sucked out of the pan and also sometimes from the lifter valley. This goes thru a multistage dry sump pump and is then sent to the storage tank. It is then pulled back through the pump and pumped back in to the engine. Along the way it passes through a series of filters, oil coolers, yards of stainless braided hose and occasionally has a short layover in Pittsburg waiting for a connecting flight. (Still awake?) Dry sump systems are more complicated and costly than wet sumps. The average dry sump set-up has the ability to scavenge 2 to 4 times the volume that it pumps into the engine. This causes "negative crankcase pressure," which gives you horsepower. Dry sump systems also offer a more stable supply of oil in all conditions since there isn't a rapidly spinning crankshaft located right above the oil. In a nutshell a dry sump cost more but works better. Big nutshell, huh?"
