So I am trying to size an oil cooler and I have a lot of questions can concerns.

I want to make sure the flow rate is not too high for the cooler but I don't know the average flow rate.

What are the average / desirable temperatures? 180F

Does anyone use a thermostatic bypass when the oil is cold? If so how did you set this up?

Any idea what the highest temperature oil that the cooler will see?

Seeing as I already have a turbo removing some system pressure how much pressure drop is too much?

Oh, is there anyone using a two circuit radiator one for antifreeze and another for oil?

 

Bump

 

There was a coolant/oil radiator custom made many years ago (by CRS I think) but it is not production.

 

I have seen it in other threads but was not sure if it was ever produced again.
