methanol vs Ethanol

[Hemi T04]

Hi i just found this site and its exactly the forum i needed.
Ive been messing with different water injection system for the last couple of years on my turbo projects. Now recently ive been experimenting with staight ethanol(methylated spirits) or 50 % mix with water.
I used methanol initially but becuse of all the messing about and leaks(it is very toxic) i decide to use ethanol instead. Which has very similar octane and cooling abilities i am told.
So i want to ask on peoples experinces with ethanol/water injection.
It has over the years chewed into all the rubber componets and rubber fuel lines etc. but i plan on using a fuel lubrican additive from now on.
In my latest system im trying to setup a direct port water/methylated spirits system that will hande the corrosivness of the alchohol and the water. The problem isnt getting it to work- but to get it reliable for long term street use.
