As with all of my stuff, this has a rwd slant on it :-) its the only way to go i tell you.
I will finish the sump tomorrow and shrink, and upload and label all of the images.
This should be the definitive guide to rwd sumps that are not dry.
dry is the best of course, but a bit of a hassle.
the same principles apply to fwd sumps, but i've never had oil surge issues on fwds i've flogged.
basically give it as much volume down low as possible, distribute that volume off to the sides and infront and behind the pickup with suitable volumes depending on your intended usage.
for me a big rear "wing" would be best (BRAKE!! ;-) )
then, at or below the level of the oil when the engine is screaming (1 - 2 litres upstairs and in the air) you put a sealed plate over the whole lot with 2 holes
dipstick
pickup
thus all oil that falls from the engine swills around on top of this plate till it gets sucked/falls down into the pickup reservoir.
you'd think that was bad... but its not because A the oil wants to fall B the oil is being sucked down by the pump C any time the G direction isnt straight up and down, the oil cant run away... its trapped. the oil from the wing that is now up hill falls down to the pickup, and the whole lot is kept around the pickup by the lid
you might think that the oil coming down from the engine will be kept from getting to the pickup by the plate, and you are half right, it will, but if the plate were not there, that oil would just fall to the front (under brakes) anyway, and not be anywhere near the pickup
so, what we have then is a buffer of oil for the temporary period when you are pulling some G's (you are rice if you dont pull G's) sooner or later the pump will exhaust this supply and it will be all pooled on top of the plate, hopefully by this time, you are back on the gas hard for the next straight ;-)
pictures to follow tomorrow as i must finish it by then ( with the exception of the turbo drain (which should come down above the plate))
major job one from week one of the 11 week get the ute running hard fast plan nearly complete :-)
