Custom Sumps - Ideas and Inspiration

[takai]

Ok, so maybe this wont be as popular as the quad schlottle body thread, but i need some inspiration for my new sump. Currently thinking a fairly standard winged jobbie with internal flaps for oil restriction. Kind of like this one:

and


Anyone have better suggestions, or advice?

windage tray
skirt around oil pickup
sump flaps and install fixed baffles

[ed]

note the uni directional pressing

[takai]

4A has a seperate windage tray which is sandwiched between sump and block.
However, with that last picture you have posted it looks like they have installed a hinge in there for some reason and then welded it down.
Any reasons?

[ed]

its not welded down, its free to swing. note that it swings forwards - this is a drag engine sump - lots of g's under launch - trap door is for preventing slosh to the rear of the sump.

edit - im reassesing trap doors...

[takai]

Oh i see now, i thought that the lines across the bottom of the trapdoor were from where they had bent the metal. Rather it is two seperate pieces.
Understand now.

Why are you re-assessing trap doors?

[ed]

i initially disliked them...

but reading some stuff just now whilst looking for those pics, im beginning to be sold on their specfic use in winged and otherwise increased volume sumps. *shrugs* guess im just used to fixed baffles

id be wary of gunk and resin making them stick shut though

also, if youre playing with sumps, consider how youre ventilating it:

Far out, you post a hell of a lot of stuff on v-eight. +rep for you, when i can find enough other people worthy of having rep.

After talking to my head guy about his sump designs he highly recomends the pressed steel mesh, his reasons are that as oil flings off the crank in all directions, it hits the mesh and it directs it down to the sump

Lock thread!

have you seen the ARE sump for sr20s? the pick up "swings".the idea is it will move as the car leans, thus following the oil.

i dont know about moving parts in the oil pickup, but its a noval idea.

[roadsailing]

a few tips from a book i just finished reading:

make sure the pickup is between 9.525 and 6.35mm from the sump floor, to prevent surge and not restrict the pickup.

it also suggests a horizontal baffle with a hole cut in the middle just big enough for the pickup to go through (so you can fit the sump) the edges of the hole should be flared/funneled down to allow oil to go into the sump and prevent it coming up the sides.

just drysump it

you have vented both cam covers on your race engine haven't you? you might be able to run two inlet covers for that JDM tuner look (i need to confirm you can do this on smallports)

[gearb0x]

Is there any reason why the book quotes such precise figures for the distance between the pick up and the sump floor? just seems a bit wierd :S

[Dimitri]

theyer conversion from imperial 6.35mm is 1/4" ect..

[roadsailing]

dimitri is on the money, should have just written them in imperial i guess.

check this site for horizontal pickup plate pics:

had a look at my spare engine, the inlet cam cover does seem to fit on the exhaust cam. probably a good idea to grind down the sparkplug cover bolt lugs on the side, but they are useless anyway.

i think i'll use two inlet cam covers on my next engine.

Has anyone ever done an electric dry-sump setup?

What I mean is say 2 moderate pressure, decent flow efi fuel pumps, to the oil tank, and a flexible steel oil line from the oil tank to the side of the sump, and another flexible line internally to the normal fuel pump.

Assuming there was some sort of detection for if the pumps died with a big fuckoff light. To warn the driver, do you think it could work?

Yeah, one of my problems there is that i actually use the spark plug cover bolts to mount the SR20 coils. Ill probably end up cutting of fthe stock PCV and welding it up and instead welding a pair of Speedflow bosses on the covers and doing everything that way.

I currently have an ST205 sump lying around that i would like to use later on, i'll probably be getting a windage tray as well (similar to the one TurboRA28 has) but was curious whether some trap doors would be of benefit. keep in mind this is for a FWD layout.

I may also make up a plate to cover the lower part of the sump pan so that it encloses the pickup.
