not locost! - PACE 6 stage dry sump
Not locost, but there are all sorts on here so worth a post I think. 
I have for sale a brand new PACE dry sump pump, complete with barrel-type relief valve, 78mm pulley on pump, 62mm pulley for driving, and new
Continental 225L drive belt.
The pump is of a modular design, fully O-ring sealed.
With 6 stages fitted this becomes a serious bit of kit, intended for high spec/high speed/large capacity race engines. It was going to be used on a
Ferrari 3.5L V8 powered single seater competing in the EuroBoss Series (£multi-hundred-thousand pound racecars).
I have bought the engine but intend to return to the standard Ferrari dry sump for my project, hence this sale.
The following picture shows how we intended to run the pump on the V8 engine.
A, B, C - Scavenge sump
E, F - Scavenge heads
D - Feed to pump from oil reservoir
J - Pressured oil to filter
G, H, I, K, L - scavenged oil returns to reservoir
This set up will enable not only the traditional benefits of a dry sump system but will also be able to pull a significant vacuum on the
crankcases/cylinder heads which will significantly reduce windage losses, reduce total engine FMEP and hence directly increase BMEP (torque)
particularly at high engine speeds. In some cases this crankcase vacuum can also allow an experienced engine builder to utilise lower tangential force
piston rings which will of course further reduce engine friction.
Overall length ~360mm
Overall housing dimensions 83mm x 75mm
£1100
I have some JIC fittings and a MOCAL remote oil filter housing and filter that I might throw in by negotiation.
More pictures to help the sale:
I also have a custom sump for a Ferrari 355 which is 2 inches shorter than standard. Only really useful if you have a Ferrari F355 Challenge car or
similar though! 
PM me on here or contact 07904061484. Happy to post worldwide.
cheers,

Hi
Sorry that this isn't for me (and I wish it was), but I have a technical question - how would you actually plumb that into the head such that it
scavenges?
Thanks

Hi Mark,
They were to be mounted on the cam cover where you would more traditionally expect to find a breather. (Another advantage of this set up is that it
allows you to remove all breathers, breather labyrinths, and potentially catch tank from the engine)
In any typical OHC engine oil is generally fed to camshaft bearing journals and valvetrain via drillings, after which it just gets whipped into oil
mist above the cams. Normally this oil then collects again in the head and runs down passages or the camchain chest to the sump, splashing onto the
rotating crankshaft assembly on it's way past.
The head scavenges would mount on the cam cover above the valvetrain and try to pull as much oil mist as possible so that drain back to the sump is
minimised. On our typical engine the OD of the crank webs will be doing around 175mph at 7500rpm so every bit of oil you remove that they would
otherwise have to smash through gives you significant windage benefits!
cheers,
Pat

Thanks for that- that's really great detailed info. In the duratec the oil runs are down the side of the block and they drop into the sides of
the sump rather than on the crank. Ford did a lovely job on the design of this.
