This is probably something very little of us do, but has anyone here installed an oil cooler off of something like an Audi or a Saab? I have an oil cooler with some lines running in and out.
I'm not sure where or what to do with it! I thought maybe of Ting it off from the oil feed, but I wasnt sure that there would be enough pump pressure to feed it through it and to the turbo soon enough?

If anyone has done a home made oil cooler setup, I'd love to see pics of at least get some idea of where to install this!

 

how about this:

Thanks alot!

 

good site!

 

I'm dumb. how does an oil cooler help? does it help with the life of the motor or will it give a few extra ponies?

The oil cooler is a radiator for your oil.It will extend the life of your oil by keeping it cooler and there for not breaking down the oil viscosity due to high temperature.It helps in turbo applications becouse as you proabably allready know turbos get extremely hot and they need oil to lubricate bearings and help keep them cool and since a naturaly aspirated moter isnt set up to run such high temp the oil will break down verry quickly.
As for your other question,no it wont add anny H.P but it will help your newly turboed engine live longer.

So cooler oil temp.=longer oil life=less friction=no loss of H.P!

Hope this helps

 

You're right, the hard part is that you need to know if the oil cooler will actually benefit you before you go out and get one. Oil needs to operate at a certain temperature, having the oil at too low of a temperature is almost as bad as having it at too high of a temperature....the solution? know your oil's temperature and get a thermostatic switch that diverts oil to the cooler only at a given temp. good luck!

 

umm thats not neccessary. no thermostat switched cooler. thats just way too much work, the cooler wont cool it to anywhere near air temp and the oil has to be quite cold before its viscosity is high enough to hurt performance.

 

woops, thought I was in the Mclaren forum.

 

LOL...

I was just thinking that tapping the oil presure sender from the back of the block might be too much oil presure and push past the turbo oil seals... A oil cooler would drop the presure slightly between the turbo and the block feed, BUT... Is the high presure really that high ? And even if you were to use that to install and oil cooler, its going to cooler the turbos oil, but by the time the oil comes out the turbo, its going to be hot as hell again.

If the preusre is too high, then the oil cooler will prob. extend the life of the turbo greatly, but not do a whole lot for the engines oil.

If the presure ISN'T real high, then the cooler could possibly drop the presure too much and cause the turbo to die early..

What is the normal presure coming from the oil sender ( kinda a dumb question ) and what is the "right" oil preusre that a given turbo requires ?

Maybe I'll do one on my TD04-13G b/c they are kinda weak compared to most garrett T3 that have much larger bears etc.
