homemade,cheap dry sump?

[x6rs]

hi, im thinking about building some kind of dry sump for my stroker projekt,

ist there anybody who has done it before or have any good ideas? pictures is always nice also

maybe use an external oilpump like the one old saab 99's use, to suck the oil out and use the oem pump to push it back into the engine? any ideas? how does the vac-u-pan work?

My car, non Audi has a custom dry sump setup.

It uses a Pace pump. The pan is a modified item, I believe there are pans available for the I5 but not cheap, really there is no such thing a cheap good dry sump system, inc hoses and a tank you are looking at nearly £2000, even if you use cheap hose its still a expensive modification and needs to be right or you are wasting your time.

Jeffer used to make a starter kit.

Repo and Aelred both make dry sump kits

Dry sumps are very expensive as JB says look 2k plus

I brought my Weaver stage for pump almost need for £300 a tank which was like 3 gallon this had to be modified cost me $10 second hand postage was 6 times that and a brand new paterson in line filter for $20. Pre heaters x4 free

I now am having a CNC'd front blanking plate made and a sump pan flange water cut from the original.

So far it owes me around £600

Pretty good i would say!

But do not for get fittings and then pump screens these will be a fair few £££

[terrybullwon]

In fact if you want a front blanking plate or a flange let me know it will bring the cost down

thank you terry, but im still thinking about using the oem pump for pressureising, i dont think the pump itself is bad, i think it can make both the pressure and the flow i need, the biggest issue is just how to attach it to the tank, and a oilpump from a saab 99 isnt bad either from what ive heard, maybe it would supply enough flow to keep a good level in the tank..

in that case i probably could make most of the parts i need by myself, got most of the machines i need at work and im not afraid of fabricating welding the old sump pan maybe a bit tricky if i try it myself(welded alot with TIG but never alu) but i know a few people who maybe can help me with that. just need to figure out how it should look.

the hoses on the other hand has to be bought, but i think industrial hydraulic hoses would do the trick, i know there is hoses who can handle both the heat and the pressure quite cheap.

a tank i can fabricate myself,but i dont know how it should look, just a regular tank?

maybe it can be done on a budget, i really dont think(or hope) that its "rocket science" building a working dry sump.

but what do you guys think of using the oem oilpump for pressure and an external pump for sucking the pan? would i be able to use the original oilsquirters etc and not change anything inside the engine?

What purpose do you intend to use the dry sump for? I plan to do one, but mostly in order to rev above 8500. It seems that the stock pumps don't like going higher than that. Of course, having a dry sump is good for helping with oil starvation. However, my point is that if you are just using it for oil starvation purposes, maybe an accusump is a better idea for you. If you are doing it to rev higher, then stock pump (in an external app) isn't going to cut it.

Terry, what is the front blanking plate for? I might be interested in some parts to start a dry sump. Most important is the pump. Everyone I've talked to who makes pumps sells them for $1k USD or more! I wish there was a better option. The bodies aren't that hard to make...its the gears that are expensive to make I guess.

What about using a 1stage pump wich take oil from bottom of oil pan, a blind flange istead of oil pump and a inlet at the same place as the oem pump?

[x6rs]

its the oil starvation purposes, want to do a lot of track driving, i dont need to rev beyond 7500rpms yet i think. and also you gain some free hp from a dry sump wich isnt bad either, better pistonring sealing. but shure ive been looking at the accusump to, seems like an easy way of get suffiecent oil all the time im planning on driving my car very hard, would like to try drifting like the norwegian brothers too, so sufficient oil pressure has to be 100%

The BTCC engines run accusumps due to dry sumping not being allowed by the rules. I'm using a Accusump on a car I'm doing as its a cheaper modification that does work.

A friend of mine works on the nuclear Submarines and every hydraulic system runs a accusump for back up so it does sort of show how well they must work as there is no room for error when your a few miles under the ocean !

I wonder if it can be used dry sump and hydro lifters with stronger lifter springs for high RPM - 8500-9000?

[G60Rallye]

Dry sump and cheap just dont go together in the same sentance!

[|CL|NIKI]

Oh- its not cheap at all. But are we certainly need to use mechanical lifters+springs+titanium retainers and dry sump for high rpm?

[terrybullwon]

Depends on why you want to rev that high?

Will your cams match the need for a larger turbo to go that high or is it a punchy race motor ?

Standard cams on a dry sump system will be pretty pointless also
