Winged Sumps ?

I've just spotted that further back in the thread cheers. Still no clearer then, I was sold it as an unidentified but possibly rare motors port sump! A load of flannel no doubt.

 

^^ As an Audi 80's engine is mounted north south, that sump is not suitable to a transverse application.
You will find the majority of sumps that appear 'winged' are really in applications that are north south, with a deep reservoir in the front or rear of the sump.

 

Yes Mushy said that's what often happens when it's realy an Audi 80 sump

 

Yeah I can imagine, paid 200 for the blighter :0

 

Ouch that's nearly as much as my awesome oettinger sump stands me at

 

Is this it ... "62"

cylinder block with pistons / 1.6/1.7ltr. / 4 cylinder
cylinder head / oil sump / cylinder block with pistons / 1.6/1.7ltr. / YN,YG,YH,YK,
cylinder head
/ YP,YT,YZ,YY, WY,WZ,WP,WT, DIESEL:CR



Other ... "55"

cylinder block with pistons / 1.3-1.8ltr. / 4 cylinder
oil sump / cylinder block with pistons / 1.3-1.8ltr. / YP,YZ,WV,EP,
oil sump
/ WY,WP,WT,DS, DZ,DT,JU,JV, JN, DIESEL:CR,JK T-DIESEL:CY

 

^^^^^ yes thats it,they were only fitted to the gte models

 

`76` GTE ident below, the first one above is from `79` models where the part number does not reference specific models hence maybe on others ?

41A ---------
no longer available
/ 80GT,GTE

 

I`ll take that a compliment then lol

 

So to continue with my own sump, I have been trying to employ what has been discussed. Initially I gave this a go:

A couple of traditional fences that would have trapdoors on them.



And a scavenge area to return oil primarily to the pickup area.













So in this particular design the windage tray would still serve it's purpose and all oil draining past it would be directed to the pickup area first. Along with this, I thought ti would be a good idea to remove the chamfer at the front of the sump in order to increase the depth of oil in front of the pickup.

I though about the area around the pickup a little more and think a diamond shaped box with 4 trapdoors would be better suited?



Hmmm, maybe a little small. So increased it's size.





The tray would need the middle drain altered to match the diamond box.




Thinking is that a diamond shaped box is a better shape to keep oil near the pickup and the orientation of the box is better for filling up with oil.

What do you think?

Don't think it'd make any odds so I'd go for the easiest to fabricate option

For a few minutes I thought the square would be better the decide probably no difference at all .

 

Maybe a little tight around the pick up ?

Will the trap doors be able to allow the oil into the `diamond` quick enough ?

Only two of the trap doors will `operate` at any one time ?

Make the trap doors half the depth of the `diamond` ?

 

Thanks James. Those are some valid questions to think about.

Maybe a little tight around the pick up ?

I'm not sure tbh but I'll check the area of it. I'm pretty sure its almost the size of the traditional baffled approach.

Will the trap doors be able to allow the oil into the `diamond` quick enough ?

I'll need to test this tbh. There will also be oil draining back in from the tray the drains oil back into the pickup area too. I can't seem to find flow rate info on the pump anywhere. That would help massively.

Only two of the trap doors will `operate` at any one time ?

Yup. Pretty much where ever oil pushes them open which should be 2x doors as you say.

Make the trap doors half the depth of the `diamond` ?

I currently have some ally piano hinges and can get pretty much whatever height I need. But yea, large as possible.

Look forward to the result ... you`re pretty busy with the car at the moment

On the last point ...

Given that the trap doors swing both ways ... be interesting to see how surge affects them, oil in on one side and out on the other, affecting pick up OR would this be countered by the actual sump level ?

... think that I`m overthinking this

 

Thanks James. Not as busy as I'd like to be. I get very little time on it these days but when I do, I like to try and be productive.

The trapdoors will be fitted in a way that they only allow oil in and not out if you see what I mean. They will also be restricted to open less than 90 degrees. Stops them getting held open by oil trying to exit.

Someone on Northloop mentioned that it would be handy to know the oil flow rate of the pump to help work out how large to have the box in the middle.

Hugo recons in post 54 oil pumped at 6-10 ltrs per 1000 rpm

 

Brilliant! Thanks Hugo and Mike.
