I've kinda got to that point in my own mind too. The car has a factory standard oil/water heat exchanger anyway but I'm trying to cool the turbo more than it is cooled at the moment.
The turbo is air cooled only but it's on the back of the engine so there's sod all airflow - typically French design.
Would it be worthwhile using a coolant additive (purple ice?) to aid oil/water heat transfer in the meantime? |
