Yes, Amont makes valves like this for larger engines. We have them also for exhaust systems with specific aftertreatment for cold weather extended idle periods. We also have them implemented in the new Tier 3 products coming.Volvo model.. don't know. Maybe I dreamed it. Anyway it could be done with "off the shelf" boost or temperature controlled bypass valve, w/o electronics (my fav way), in the raw water CAC piping.
If I were doing my old engine, I might operate a ball valve bypass manually to test the idea then boost controlled so there would be no charge cooling at low power regardless of engine temp.
