I had a brain wave the other day but want to check with someone in the know...
As I have a manual the oil cooler in my radiator is not used. Would it be suitable for using for a turbo oil cooler? Ie oil from motor into top or cooler out bottom into turbo out of turbo into sump? Or are these not designed for this sort of pressure or is it a waste of time all together (doesn't help turbo life)? Cheers, Tim

It'll do the job o/k.. Just be aware of oil supply on start up..
If cooler is lower ? Then it should be full all the time... There won't be too much pressure through cooler as the turbo is open on outlet side.. A 2.5mm restricter pre cooler will take pressure away on "ball bearing" centre. If full oil "sleeve bearing" ?? No oil restricter is required...

Hey buddy...
Yeah its only a sleeve... So pressure is not an issue with these (you would be right to i imagine, big open body in them so pressure wouldn't hold, just needs volume not pressure?) The oil cooler in the radiator is probably just lower than the turbo but its part of the radiator so it is in line with the engine. maybe the top of it would drain back through the side of the block (back the way it came when it was running)? Is it a big deal for the couple of secs it takes to get pressure? So having not much pressure in the circuit would mean you wouldn't blow out the oil cooler into the water would you... And would it actually do anything for the turbo? Would it be better to put before the turbo or to put after the turbo to cool before it goes into the sump?

I'd just get a proper oil cooler.
the idea is to have a nice large free flowing oil return, the moment you extend the lines and put a restriction in that line (the cooler) it may start backing up oil in the turbo.

If i put it before the turbo?
or its pointless there? I hate having coolers everywhere, i just though this is there unused, if it can be i will use it, if not I wont worry about cooling the oil... It is a small turbo, just though maybe it'd prolong the sleeves? Thanks, Tim

Oil coolers are a good idea, i've got one on my turbo EF.
if you plumb the cooler in before the turbo then you need to consider the oil pressure (~15-70psi) and use lines and fittings that won't leak.

out in the country here buddy... I can get anything made up... heaps of places here that make high pressure lines for headers and other farm equipment... no worries there
 the high pressure in that internal oil cooler, wont damage and leak into the water part of the radiator will it? as this was my main concern, or transmissions have high pressure too? Thanks, Tim

haven't installed anything yet... was just brain storming one day and though oh I wonder if this works...

I would run a longer tube to turbo ??
Like some cars with power steering.. They have the pipes going infront of the radiator for cooling.. Being pipe. Thre's very little problems with oil leaks and cooler damage... Subaru and Falcons have these coolers.

Yeah I have seen that... thats not a bad idea... and that would be very pressure proof (right fittings of course)
Thanks for that idea... I might do that when I finally get my shed built and have the time and space to put the temp motor in and sort out the issues with the turbo...

something else you guys in the know might be able to help with...
If I run a big in-line pump and 24lb injectors, is it worth only triggering the big inline pump with a pressure switch so it clicks in when on boost to get good fuel economy when driving on the open road? Or with big injectors it needs the extra pressure all the time (in that case I'd go for a bigger in tank pump)... Or will this make two thirds of stuff all difference to fuel economy? only reason I ask is i notice capa's included inline pump works this way for their supercharger kit a pressure switch clicks it in and out, but they probably don't have bigger injectors... Theories guys? Cheers, Tim

I wouldn't do anything untill you know what oil temps you have.
Running through the the rad cooler would at least help to get the oil temps up faster. Cold oil is bad. But if you are using good oil, so long as the oil temps are above 95 and below 110 there is no need for cooling. |

oh thats right because cold oil doesn't run as well does it? Its the wrong viscosity...
Yeah ticky might be doing more worse than good...

Yeah ticky might be doing more worse than good... it's not a bad idea to think about this stuff though, You can get cooler setups with 'oilstats' built in. IMO is the best way to go on a street car, as %90 of the time you dont really need a cooler. But it's that %10 that can do real damage. |
