I am pondering this for 2 reasons. 1st is in regard to idiling down the turbo beyond 60 seconds under normal driving. 2nd has to do with one of the things I see here a lot where people recommend higher viscocity in a turbo application.
1st, given that the turbo is liquid cooled on top of oil circulation wouldnt it be safe to say idiling it down to cool it would be no more necessary than idiling down a naturally aspirated engine? Youd be getting high temp deposits/coaking regardless.
2md, if the oil is not being subjected to temps it would under non water cooled applications why the higher viscocity to protect the high temp areas of the turbo? Same logic as above, if this is necessary under a liquid cooled turbo applications where the oil temps average the same as the coolant then why not for naturally aspirated ones? Is this because of the temps in the turbo, while heat is being mitagated, is still higher than the hottest seen in the rest of the engine?
What, if anything, am I missing?
Thanks all
