Stupid Question: Meth / Water 50/50 injected after IC

[bwhinnen]

What inherent dangers will I see with this mix. Given that this is prior to the throttle body, prior to the externally venting BOV etc. I've read that a 50/50 mix should not be flammable (well able to sustain a flame anyway) is this correct?

On a WRX with a front mount, nozzle is mounted about 600mm from the throttle body.

Thanks in advance for answering a stupid question.
