I have methanol injection on the turbocharged Hemi. It only comes on past 7 lbs of boost(or whatever you set it to). It is about 120 octane and will last forever if you never go past your on boost level. Because it is on a turbo setup it is wired to not allow you to go into high(7+, 15 in my case) boost if you are empty. It is wired to the dual stage boost controller as a safety margin although it may be ok to go past 7 lbs without it.

Since it is high octane it allows you to add more boost without detonation and/or add more timing to your current boost level. It will also work in NA applications by allowing you to add more timing also.

It also helps cool the intake air charge depending on your water/meth ratio. More water = more cooling whereas more meth = more octane. I was at a 50/50 mix but will be going to a 70/30(meth/water) mix.
