and for ryandriftingfat, I agree with what others posted about your setup, with all due respect you need some form of pcv. Every auto manufacturer of every engine in the world has included a functional pcv system with their engine that Im aware of since it's benefits are realized. removing it is not a good idea. This is about having a cleaner healthy engine.
some good info about POWER gains while using vacuum pumps in this thread:

gearhead does bring up a very good point about trying to go for too much vac in a wet sump. Because the oil and the pump are in the pan, the depression works against the pumps ability to make pressure. There is no atmospheric pusing the oil into the pump, and the pressure relief valve/spring is missing the atmosheric pressure as well. Kind of like why you need to up the intake spring pressure on a blown deal, except in reverse. The pan depression is actually allowing the relief to blow off at a lower pressure on the gauge, which is reading oil pressure differential to the outside atmosphere. Also, with a depression in the pan, the oil had less pressure to work against in escaping the bearings. It easier for the oil to flow thru and out of the bearings in a vacuum. Again, lowering the oil pressure you see at the guage, and thats actually a better scenerio than what really happeniung in the pan. If the guage could read pressure against pan vac, the pressure would read even lower.
You need to be aware of this type of stuff when setting up a wet sump deal with a depression lower than about 12-14 inches.
Dry sumps only witness the bearing flow thru phenom because the oil and the pump are outside the pan and uneffected by the depression in the pan.
