Sump design
Ok, as we have now trial fitted the engine in the chassis with the modded sump we have, it appears that i may still need a little more ground
clearance.
So, i'm going to bin the ally sump and build a steel one.
Big question is what design.
I will be loosing a fair bit of capacity by shortening the sump so was going to go for a winged/ T shape sump pan.
Has anyone got any ideas on design for windage trays, baffling, or gates........
Some pictures or links would be nice

Here is a link to my thread on this very same subject. Mark Allansons link is very useful. I followed this - worked very well. It extends the sump
forwards instead of putting a wing on the side. This is a kind of baffle itself. The bit we cut off the top was inverted and re-fitted for another
baffle (holes vut in for dipstick and oil pick up).
Have a read and if you have more Q's - fire away.

caterham used foam in their vauxhall xe cars, though believe the foam needed replacing at every oil change to reduce risk of it breaking up and
kernakering the engine/blocking the pickup..

Yup, I'm using a Caterham foam filled sump on my XE engine. Oil depth in it is around 40mm!!
I have heard a few horror stories with foam, but then I recently discovered that a number of single seater racers use it in their sumps where dry
sumping is not allowed, and in PPC mag a couple of issues back they had the sump from a car that has raced for many years with a foam filled sump with
no foam changes and no problems.

maybe it depends on the type/quality of the foam used..?!
manta and other cut/shut sumps use a t-shape/winged arrangement, maybe worth a look/see if anyone can post piccies..
Alternative I guess would be something like an accusump? or add an oil cooler to increase oil capacity?

I fabricated a steel sump for my duratec.
It was well baffled and I fitted 4 off, one way flap plates to allow flow into the pickup area but restricted flow out.
There are some pictures in my archive but not of the inside, I try to add some.
Cheers,
Colin

Heres a few shots of an alloy baffled 5 ltr low profile sump for my 4AGE "Blacktop" 20V motor.
I just bought this from BPJ Services but isn't cheap or particularly light. The factory windage plate is retained.

Mines a bit cruder, but probably a bit cheaper.

CairB,
You made it your self so its a true locost sump!
Anyway looks perfectly decent to me and probably a lot lighter too. I was going to wait for RAW to fabricate from steel but my current sump wont last
much longer from the looks of it.

thanks for your replys
I have already got an accusump that i'm going to fit, and an oil cooler.
The original sump on the alfa is all cast ally, so it will be ditched and replaced with a home made one.
I think i will build it 'T' shaped with horizontal across like the original, and with some of those gates/flap things aswell.
I assume they are made from thin steel, cos i've seen some rubber ones somewhere aswell.
Should i get the capacty of the sump the same as the original or increase it.
It will have the addition oil in the cooler and pipework, and also the 1.5 ltr accusump and pipework ?
Also do they

bimbleuk,
Thanks for that.
I was in the garage thinking mmm lowline sump on the one hand £450, on the other £0 but a lot of sweat... no contest
It doesn't weigh much different to the aluminium floor scraper that came with the engine.
As I've managed to ground it on an unsuspecting sleeping bobby I'm glad I did it with this and not an ally one.
Cheers,
Colin

Yep the partitions and gates are made from steel.
I do the odd bit of computer work for a few automotive companies so I usually get things at trade. Otherwise I would had thought twice about spending
£375+VAT on a sump!

Trev, I suspect your sump will be of the 'Locost' ethics??

ok i now have a the basics of my sump.
Its looks like a big icecream tub.
I have an extra litre of oil to play with, but how should i best stop the oil moving away from the pick-up.
The oil level is only going to be about 70mm, is this too small?
What the best way of stopping it starving.
Having looked on a few other sites, it seem that a box around the pickup with trap doors is the way to go.
with the oil draing into the box.
As I now have a very flat, oblong box to mess around with, has any one got any good ideas
