We'll be putting together a package and adding it to our website.



Injecting just water will only improve knock resistance. The methanol will lower intake air temperatures more than just water alone in addition to having a higher knock resistance than gasoline. Jordo and I had a good discussion in a different thread that went into more detail.

If you are doing water/methanol or just straight water, you MUST use DISTILLED water! Any dissolved solids will clog the injectors over time! Think about how often you have to clean/replace the aerator screen in your faucets at home...especially in SoCal where we have nasty, hard water that is barely potable. You do not want that dissolved lime and crap in your motor do you?



Like Nix said, we Americans rate our fuel on the conservative side. Our 91 octane is comparable to your 95 octane and our 93 octane is comparable to your 98 octane.

As far as how it would impact the S/C kit, you would run a little richer on higher octane fuel as it would have less propensity to fully combust. Therefore, you would have a conservative tune for your conditions...nothing wrong with that.
