Hi i'm new - but have water injection - advice needed

[Gadget]

Hi Guys

what a great site !!!

I used to use water injection because my ACT's were getting too high and my ecu was retarding the ignmition - however it seemd to loose me a lot of power and in the end i used a large intercooler instead

I now have a spare water injection system and wondered if it could be used to get more power by filling it with methanol or something else

Is methanol dangerous to use particually the way it corrodes aluninium ?

My next questions is Propane Injection

has anyone on here used propane injection - i'd consider using this as am eans of geting more power - apparently it works like an antidetonant anyway slowing the burn ?

any opinions on this ?
