In this case a square has more area than a round tube and attracts oil, via surface tension, to the pickup area. Or you are distributing the p; /html/land-speed/2008-12/msg00231.html (8,273 bytes)

Re: [Land-speed] Dry Sump (score: 1): Author: "Jim Dincau" <jdincau@qnet.com>; Date: Wed, 31 Dec 2008 20:03:07 -0800; External screens are conducive to proper maintenance whether integral with the outlet on the pan or in line. The screened pickups require the pan be dropped, the windage tray removed and in some cas; /html/land-speed/2008-12/msg00232.html (6,681 bytes)

I've pretty much decided to go with the 'status quo' of screened-boxed pick-ups. Actually found the very u-weld pick-up kit i; /html/land-speed/2008-12/msg00233.html (10,065 bytes)

Heard a story, BS or not about a Pro/Stock team dyno testing the bottom end for least oil windage. Best HP 1380. Then one suggested filling the oil tank and; /html/land-speed/2008-12/msg00234.html (7,551 bytes)

Hence my question. It appears that the actual numbers are hard to get or nobody has them (w; /html/land-speed/2009-01/msg00006.html (10,139 bytes)

[Land-speed] Dry Sump (score: 1): Author: "Elon" <saltfever@comcast.net>; Date: Fri, 2 Jan 2009 16:55:26 -0800; Skip, after you raised the question I went out and put a torque wrench my 4 stage, Moroso, gerotor pump. The problem with quantifying ''dry sump'' is there are too many variables. HP will vary with,; /html/land-speed/2009-01/msg00020.html (7,491 bytes)

If nobody has the numbers, I think that I will start by measuring the torque used to drive my BBC HV oil pump with the drill for preoiling.

He even built a clear plastic oil pan about 3 feet deep. His justification for dry sump was it could remove almost all of the air fro; /html/land-speed/2009-01/msg00046.html (9,676 bytes)
