Think this depends. As I mentioned, I was able to be more aggressive on ignition timing with 50/50 without Kr. Water just does a better job absorbing heat. I do agree that it is application dependent. If I were racing the car and counting on consistent ET's or 1/2 mile times vs. street use I would use 100 percent meth. Same if I were high boost.

Yeah, but an automatically regenerating supply hasn't been done before as far as I know. I thought that was pretty cool. Bmw is working on that for future models.

The new M4 GTS (should be out very soon) comes with factory water injection, too. Though it has a reservoir that needs to be filled. I'm not sure if it'll be water or something else, though.
