water mixture help?

[white90]

i went to the track today. i melted the electrodes on some plugs. not bad just back a little. my question is, would the mixture effect this? i was injecting 60% alky, and 40% water. if i run 1/3 alky and 2/3 water would this help? if not i will have to pull some timing. thanks for the help

also should i switch from alky to methanol. im running the 70% alky isopro solution. which would have the best effect and what percent. thanks again
