If it does your engine won't be too happy.
That is true to an extent, but only if you tune for it...we never recommend tuning for the Meth, because if there is an issue with delivery or you run out etc, you can run into an issue. However if you use it simply as additional cooling, you wont run into this issue.
There are also failsafes made that can be run with the water/meth system that can prevent issues from cropping up.
