Thanks for your detailed explantion Llew.

Thanks for that.
so is this a step in the right direction for a UK system.

Actually Llew the US pumps are more often ge-rotor type with the older brands like Weaver, Barnes etc sticking with spur gears. But now Peterson have gone over to the rootes type blade pumps. The spur gears don't have anything like the scavenge vacuum of a rotor and a rootes types has the best of them all.
he problem with the UK pumps are they are of poor design and leak as they often have no o rings between stages and the fitting well they are just disgraceful. Also the US pumps have higher volume stages so you don't have the problems with fluid volume at big rev's with large clearances like the pommie pumps and the US pumps pull more vacuum so you can actually slow the pumps down for less drag again

Thanks Guys, but anyone have anything to say about the OPI system?
Also, with an external pump, how does the under piston squirters work on a YB?

JP

[wayovermyhead]

Yes your right Danny, I was just using the spur gear as an example of the differences compared to a geroter. The Roots style is just a variation of a spur gear with a different gear profile, but same pumping principles. And I think your showing your age here a bit Danny peterson and pretty much all other mainstream US manufacturers have been making either spur or roots style for the best part of the last ten years!

JP, The OPI looks a hell of a lot better on paper/pictures than the other offerings. But, who knows?? try one and find out, or if you want peace of mind as to what your getting go with something like a Peterson or Dailey (the dailey's really are extremely well made)

The oil squirters just feed off the blocks oiling system, no need to feed them direct from the pump if that's what you were thinking?
As for weather the pump will have enough capacity to feed them, it would be very unlikely any decent pump will be not capable, and if you found pressure dropping off at high revs/temp then you can adjust the pump speed to compensate, providing that doesn't lead to cavitation.
Basically pump speed is a trade off between oil flow demand, cavitation and efficiency (you only want to run it as fast as you need)
So it's a totally tunable system. Pretty much every off the shelf pump will cater for all but the most extreme setups as they are all bigger than they need to be. some manufacturers will offer custom sized stages, but they are more suited to huge drag motors with massive oil demands.

WRC or YBP oil squirters tap in to the main oil gallery that runs from front to back of block.

[jpayne]

Thanks guys, are the squirters an engine strip to have machined in?

JP

[jsa]

It would be difficult partially assembled.

[jpayne]

Well that seals that. it can wait till it needs a rebuild in 20 years! Not pulling it apart at this stage.
Thanks Guys

Well that was painfull, but its done now!

Just need a place to live now! with shed and the build can continue. I will be too old to drive it! but Daughter is alomst 4 so only a few years from trying! Better get myself into gear

back to Scotties?.......

[jpayne]

Pretty much, mate.
Though a house with a decent garage is on the cards rather than the workshop in golden grove. But I did like the workshop!
But it was 35 minutes away every time!
JP

[jpayne]

Bought a house,
moved in
bough a volvo,
modified it
haven't built the shed
spend half my working week in Brisbane
sat this next to the Escort

You wont regret it as I have the SDL and it's sensational and theres not much difference apart from the plug

[jpayne]

way too long between doing anything.
first time in over 20 years everything I own is on the one property and country!
Moved the escort home a while ago, still awaiting planning permits or the garage but It just had to come home.
Been collecting parts again rather than lie under it plus working from home with a 5 year old leaves no time for playing.

But stopped the bloody bonnet hitting me on the head every time I bumped the original bonnet stay

Was digging through some boxes and thought id fit these as I'm planning the wiring loom...why oh why is one a different colour!

have ordered up boost hoses, radiator hose components, fuel pipe, hose and fitting. still cant find anywhere to mount the oil cooler and played with my floor mounted pedal box!

JP

[jpayne]

Ohh this is going to be tight...might not fit as the clutch foot is pushed sideways by the strering column, but if I only need minimal accelerator movement it might clear the roll cage forward bars.

This should be easier, time consuming but easier as the DBW throttle body wont fit which cuts down on 6 wires

Oh discovered what the grinding sound was when rolling it, outer ball joints are rubbing on the brake disk in the built for the escort brake kit!

Ive forgotten the pain of new parts not fitting!

Sometimes your lucky.
camshaft position sensor trigger bolted into the camshaft with no modifications. Im guessing Mountune just do it!

Lower hose modification, still a bit of hose and aluminium trimming to go

Running through ECU wires and plugs and having cam cover machined for the cam sensor boss. Little steps!
trying to work out wheer to mount the oil cooler as its full in front of the engine. probably behind left headlight at this stage.

Post is slow! but they finally arrived, could only get them in blue at the price I was prepared to pay. Also got clear indicator lenses and a cosworth sandwich plate oh and rack end extenders

And had the rocker cover machined for this so Distributor delete finished. Anyone need a brand new Cosworth distributor!
