After wondering which is better (wet or dry bearings) and surfing the net for answers, I finally answered my own question: which is better and why?

It appears that wet bearings add some extra safety when shutting the car down. If you let the car cycle down properely, then dry bearings are just fine.

Now remember you still have oil running in the turbos so I don't mean bone dry! I was just thinking that by removing the bearing/turbo heat from the coolant system that might take some of the load off the coolant system and give it more margine. You also have to figure that the oil system is going to get some increase temperatures, but the fact that you are only spinning one turbo instead of two might make this a wash.

If anyone else has any more concrete data they would like to pitch in I would love to hear it. I just thought I might post so if anyone else had the same question I did they might learn something too!
