Water/meth injection works, I would have blown-up or melted my motor years ago if it didnt. I test my system once a month with an ohm meter, air source and air pressure regulator. I also have an indicator lamp to let me know when the pump is operating. I have e85 local to me and I have thought of using it but I dont need it! I have ran up to 20psi. in my ford on 93 octane w/iron heads.
2 things I wont do again... buy race gas or build a high compression engine.
