Winged Sumps ?

Some pics off the net there used to be some good ones is some Motorsport baffeled sumps in the Motorsport porn thread but they've gone
So a couple with gate both metal and plastic

 

Just found this.

Sounds like a good idea need to look at oil pumps to see if it can be done but seems to make sense when taking into account Hugo's post 54
The above thread dried up so could be a dead end lol

Picture off the net of pressure release valve , so a pipe from here to the pickup area would return surplus oil straight back to the beginning of the oil system

Ipad being stupid so can't post picture but looks possible :

 

A Cosworth DFV V8 pumps 50L / minute against a 6.9 Bar pressure relieve valve setting.


By having a look at dry sump pumps with similar gears we could say somewhere between 6 - 12 L / min
and our 16V /20V oil pump gears pump quite big volume ...lets go as a start from 9L /min at 7000 rpm > 63 L
BUT our pump runs at half speed > 31.5 L / min
OR ca 0.5 L / sec .....it can be more or less... could be a baseline to start with.

The centre box has a 0.6 L volume (100 x 100 x 60 height)
And the 4 trapdoors need each an own oil feed.... L / R corners, brake, acceleration.... otherwise its meaningless

 

Thanks Hugo for your very helpful input.

The box the I have made in cardboard is 110 x 110 x 65 as it stands currently so that has a volume of 786cm^2 i.e 0.786L given that 31.5L/min is 0.525L/s as you say, the box sounds adequate.

So would something like this to create quadrants be ok for oil supply?

With my friendly fabricator too busy to help out with the ally sump, I decided to employ lessons learnt to a steel sump. Time is ticking on and I'd really like to get motoring again.

So I started off by cutting the front of the sump open and kicking it out to deepen it.



I bought a cheap profile gauge from Wilko. This really helped to make profiled plates and reduced faffing time massively. It's not the best gauge but good enough to do the job.



The baffle plates were mocked in card before being cut out of 2mm mild steel. The upper profile was taken from the windage tray with clearance for the oil pickup pipe.



The kicked out section was welded inside and out before testing for leaks. There was a slight weep that was corrected.



I decided to use aluminium piano hinges for the trapdoors. These have been riveted in place. I also punched out the aluminium hinge pin and replaced it with one from a steel piano hinge. This allowed the ends to be bent to act as angle limiters and have the bonus of being ever so slightly thinner giving a free moving flap.





An oil return for the turbo was welded in.



Along with the baffles.







Given that the gap between the flap and the sump floor is important, I reinforced the base of the sump to protect against knocks or jacking.





Lastly some restrictors have been added along the front and back of the sump stop oil splashing up during hard braking or acceleration.



I did the compulsory slosh test with some thinners and the sump manages to control the fluid well, keeping it at the desired location.

This is exactly what I need to do to mine if overfilling doesn't work.

 

I have a Schrick baffled sump like this already:



So I shouldn't be getting oil surge unless the oil level is wrong. I think mines actually underfilled when running due to the oil cooler.

 

Pretty sure I do, but it was 7 years ago now! lol
