Has anyone on here managed to come up with any cheap dry sump ideas?thinking of pulling the engine out to change the timing chain,and although i've had no issues with my shortened sump its always on the back of my head this is an expensive motor to wreck when I get it to a track.be an ideal time to drysump it but i don't think the bankmanager would be too pleased if I go down the road to demongeeks!
expensive motor to wreck...locost dry sump...
does not compute!
Many moons ago I had a GB engineering (Geoff Berrisford of grass track fame) dry sump, it was pinto pump gears in a machined alloy block, this acted
as the scavenge pump clearing the sump to tank, the oil pick up was from the tank through a hole in the side of the sump to the original pick up,
this was sealed either side with what I call bonded seals probably known by some other name.
Pump was belt driven via a extra pulley on the crank pulley, worked well.
Lol I guess! I just can't help thinking that us car people get ripped off for what's essentially a couple of pumps and a abit of a tank!there's hundreds of similar systems where I work which are far more substantial and half the cost,unfortunately my strikers not 3 phase!
It was along those lines I was thinking,very easy to get to the pickup on my engine,and i'm pretty fortunate between work,friends works and workshops can get pretty much anything made for pennies too.just sourcing the right pumps etc ideas
I've wondered in the past if a power steering pump could be used for a Locost scavenge pump.
Dry sump pumps are ridiculously expensive! I've been trying to persuade myself I need one but I really don't
you will get ripped off at demongeeks - they do keep the stuff in stock etc...
but they do know how to charge! they even sell caterham bits for more than caterham do 
I just got a couple of odds and ends from Quaife direct (at there normal rrp) and saved myself 20% on demon thieves price 
I say always go direct to the manufacturer whenever you can...

I machined some new pump housings from ali and used 3 sets of MI16 oil pump gears for twin scavenge and a pressure stage. This was all submersible in an external oil tank. Its not installed in anything yet (or finished for that matter) its an experiment really
Accusump is poor-mans dry-sump. I just got one delivered from TRE (same as link) with EPC valve and brackets. Total cost (including shipping and
VAT was £280.
Top tip, if you buy from him on e-bay he has an "make an offer" which appears to have an automatic accept of $5 below the buy-it-now.

Were you having oil surge issues then Matt?
Some good information here :- http://www.oz-clubbies.com/forums/index.php?showtopic=4975&hl=dry+sump
Apparently some of the lads in New Zealand use the power steering pump from a V6 Camry for a scavenge pump. It's a two stage pump - one for the
power steering and the other for a hydraulic powered cooling fan. Pulley sizes are apparently critical to ensure the thing isn't run too
fast.
With this arrangement, the existing engine oil pump is retained as the pressure stage - the power steering pump provides two stage scavenge.
No other details unfortunately ...
Cheers for the replies fellas.I feel afew experiments coming on.as for weeks i'm fully aware the place is a rip off,having said that tho at mates rates occasionally things are cheaper than paying postage etc off the web.not often tho!
Second the accusump comments - I never had any issues with oil surge since installing one.
I paid £45 for my accusump from the good old US of A. delivered.
In fact I ended up buying three.
the first was a gravity one, very simple indeed, the second was a bloody big one, and the £45 one was a brand new one in the box
They seem to use them a lot more over the pond.
A very basic gravity fed one with no bladder, could be made from an old co2 fire extinguisher cylinder.
real locost
