Has anyone any experience of doing this rather than use the small bore std pipes ? Is there a limiting size of bore before the turbo gets "too much " oil or is that not an issue ? If youve done this , what did you use on the Oil pressure block as an adaptor as i believe its 1/4 bsp ???

does it not need to be smaller diameter, to the flow is under a greater pressure??

i run -6 from my remote oil housing to the turbo

Your engine should be producing 50-60 psi at full chat so i dont see it being a problem , im mainly concerned about the turbo core having that much oil in it that it cant drain it quick enough and it starts to blow through the seals ???

I presume it's not a pressure issue, but a flow issue.

Personally, I'd not be too bothered about the pipe being restrictive when the actual hole feed into the turbo is fairly small!

Ian M

the size of the hole in the turbo oil feed line adaptor determines how much oil the turbo gets. if you open that hole up oil cannot drain back to the sump quickly enough and is then forced past the seals resulting in clouds of blue smoke.

Ive got the Turbo fitting but the other end on the block that screws into the Actual engine is a funny thread and has a convex fittment unlike a JIC one . Just want to know if its worth doing really and has any benefit for turbo lubrication .

I dont believe you actually need to run any oil through the turbo Maybes thats where Im going wrong?What do you think mate!

Ian M

the hole in the turbo fitting is a calibrated orrifice. so no matter what size pipe you fit it will only get the same amount of oil. imho i see no advantage.

Ian M

i am quite sure many people will be able to testify that you do need oil or you will destroy the turbo in less than a minute.!!!!!!!!!!

You REALLY do need to. You may be getting confused with water matey.

Ryan

he's taking the cronic piss mate,

unless you are aswell?

damn its too early im confused

Tony Ryan

Marks wry wit is to cover the shelf of blown turbos he has now assembled ! The fitting in the top of the Turbo obviously needs replacing to allow the use of the Dash 6 pipe , this will adjust the inlet hole size by a fraction only . The reason i want o use a "made up " pipe is to prevent the original type pipes splitting , most are a good deal older than should be used and my new car has had a superficial oil fire from a std pipe splitting , thats why i prefer to make my own one up . My only concern as Ian was adressing , was that too much oil can be as bad as too little in some circumstances, im quite satisfied now that wont be the case here tho .

I have the proper 909 turbo feed pipe off a T34, comes off the remote oil filter and feed across to the turbo...onto a flanged fitting on the top of the turbo...i think thats a -4 ptfe feed....

It's of no use to me if you need the pipe or the fitting...

We have in the past drilled the feed fitting out to allow more oil into the bearing with no ill effect.

DaveEscos

ian, have you a pic of that part at all?

Ryan

dave's ears perk up when the numbers 909 pop up.

Tony Ryan

Ian , i'd be very pleased to acquire it from you , pm some details and we can go from there, i think thats preferable to playing around with a feed from the oil pressure switch block anyway !
Cheers

Tony you are inded correct I do have a dry sense of humour , I need it to see the funny side of blowing up turbos after 5-8 miles! On the serious matter of your feedpipe, the laws of hydraulics basically state that the larger diameter increase flow velocity but with reduction in pressure. Ask me one on internal ballistics or aero/thermodynamics. I was advised by various people at ND to drill out in/outlets but things are not as simple as that. flow maybe increased, good for heat dissapation but at the expense of pressure which is required to keep the bearing out of contact with the shaft. Our friend Giles must have experience in that area! To much pressure= blown seals to little= more blown turbos on the shelf! (PJ does a uprated -? size line with or without filter)

ian sibbert

Tony,

Despatched the item this afternoon...it does have -6 forged stainless ends onto the aluminium adaptor for the turbo and has a nearly new seal..

Enjoy..

hi tony , you should have give me a call mate

i use 1/4 bsp from the block to the turbo, conversion fitting from the turbo thread (m10x1.0 normally) to 1/4 bsp then a loverly piece of pipe witha ball valve in it to cut the oil supply if needed - and a quick release adapter on the feed just before the turbo
