Seems like it would take an awful lot of exposure to some really cold water to create enough temperature gradient to surpass the iron's thermal capabilities. TTI has a bunch of bottom mount systems on the market without issue, I've never seen a cracked housing from some water splashing on it.
Water vaporizes at 212F which makes it very difficult to quickly drop the temp of the housing.

in other words, they aren't in an area where they can be sprayed by rain and so on. I wouldn't want my turbos getting sprayed by water considering how hot they run...
but, if it works for you then more power to ya.
