Why different mixtures of methanol

[Charged Performance]

Hot Rod posted a link in another thread on the toxicity and handling of methanol. My short cut is to treat it like gasoline (try not to get contact with skin, breath the fumes, drink it, etc.)

Tuning is pretty close to like water injection in general except now that you are adding more "fuel" through the water injection you can lean out the gasoline mixture a little bit where you are injecting the mixture.
