Dry sump oiling on wet sump block?
I am building a small block chevy, i bought low tension oil rings for reduced friction and that little extra power, i want to puck a crankcase vacuum pump to help aid ring seal at higher rpm's, and reduced windage. but i've heard that a dry-sump oiling system introduces vacuum into the crankcase as well as increases oil control. I have looked for parts, and they are not cheap, but i found parts for an ls7 dry sump oil system for real cheap from sdparts.com, aside from an oilpan what else is needed to convert a wet sump block to dry sump oiling? and would the engine still benefit from a windage tray, crank scraper etc etc?
thank you fo the help!
Well you need to have a multi stage vacuum pump that is belt driven off of the front of the crankshaft, then you need a reservoir for the oil that the vacuum pump pulls from oil pan so that the oil pump can get a continuous supply of oil.
Really the only point of this is for stupid expensive drag race engines (you're building a sbc engine so you don't qualify) or for track cars that are cornering so hard they can't keep the oil in the bottom of the oil pan.
If you really want to see who uses this technology in drag racing, check out these people.
