How much oil flow from the turbo?

[EEEK FACTOR]

I was doing a little tinkering, and decided to check the oil pump on my turbo (2010' BD KIT, garret turbo)so I disconnected the top oil line and fired up the machine. The oil was dripping out very slowly which concerned me, so my buddy hooked up a 12 volt power supply to the pump and the oil started to come out on a steady, perfect stream. My ASSumption is that the machine doesnt quite make 12 volts at idle and should start to pump harder once you get in the throttle. Are my assumptions correct or am I simply an A$$?

I have a steady flow on my 09 M8 with the BD kit, at idle.

Ya your assumptions are correct... I was having some issues with mine becaust the previous owner thought it would be a good idea to paint the oil can black with the lid off... And it got all plugged up with paint...

I installed a clear line so I could see the flow, and ya it barely flowes anything at idle... Mine only flows 1 oz/ min when hooked up to 12 volts... Boondocker says idealy it should flow 3 oz/min... Talked to a bunch of bulders and suppliers of ball bearing turbo's and can't seem to get an exact answer on how much the tubo needs... Only that it doesn't need much... Even if it's dripping in it should be good to go...

When you rev the sled just barely above idle it starts to move some oil in... I do this for about 10 15 secs after first starting the sled to make sure I don't idle it for a while warming it up after sitting with no oil in the turbo...

On a two stroke with the Garret, just a drip is plenty of oil. Just make sure there are no obstructions. Having a clear line or a filter works well. Keep an eye on it and check your oil before each ride to make sure you have enough.

I accidentialy left my hose off and ran the sled for about 30 sec. There was at least 3-4 oz dumped out in that time, so I think that slow drip means something is wrong.

I put an oil pressure switch rated for 1 to 3 lbs on my oil line and on start up it flickers alot until the pressure builds up in the line. It will actually flicker when the oil is warmed up as well when I am on low throttle, so it cant really be flowing too much.

 

[ESCAPE TIME]

Yeah, they only need very little oil,I've heard that to much oil can also wash the bearings and be harmful to the seals etc.

I think the viscosity of the oil also makes a difference. Too thin can go threw the seals, but then mayby that's with to much pressure. I'm trying shell sythetic 2 stroke oil and I haven't had any blow threw, but thinking of changing to straite light weight motor oil. I also run a clear line cuz I'm just abit paranoid of the pump quiting.
So is it normal for my ball berring turbo to still be spooling down after 30 seconds of shut down?

Thanks for your help boys, I think I found the issue, I believe (I will cofirm this weeekend) the pump was wired into a AC power supply and not a DC. From what I now understand that would cause the pump to react differently(I didnt install the kit). To answer your question......an actual 30 seconds seems like a long time, but mine definetly spools down for a bit after shut down.

supply pressure

I have read that the supply pressure to a garrett bb turbo should be 30psi. Obviously people are not even close to this and their turbos seem to be holding up, at least short term.

I heard this aswell... But I think in those apps there is a tiny orfice just inside the turbo oil inlet to slow down the flow... I think the kit builders are removing that or just ordering the turbo's without the reducer...

Very important that you get a dc converter if its an 09 or 10 if you hook the oil pump up to the acc plug and its not dc it will take circuit board out.


The boot line is the one closest to engine on waist gate.

We have a bunch od dc power supplies can make you a deal and feel free to give me a call if you need more help..

Thank Kevin
