I ran a KKK with water cooled center section for 3 years without coolant to it.

Agreed, the only reason Mitsubishi, then KKK and Garrett, added coolant to the CHRA was to help with longevity and to help lower the chance of the oil coking in the bearing assembly over the life span of an OEM turbo which is usually figured as 100,000 miles.
