Hey guys, first post here but I have lurked for a while. I drive a 2006 Subaru WRX that is pretty modified hehe but anyways I should be getting a Honda Fit here soon so I can feel more a part of this site. Water injection or Methanol injection is a great tool for extracting more power from cars, especially turbo charged ones like mine. The octane boost, latent heat of evaporation, air and cylinder cooling effects can be enormous with alcohol injection. This has been seen since Turbo Buicks started doing it many moons ago. I have read some hints here and there that methanol actually reduces emissions drastically- something like 30% by keeping cylinder temps down, ensuring a more complete burn etc. Does anyone have any information about this? I am very interested in finding ways to mechanically improve my mileage. I have already used a very lean map for my car on my commute and it has helped drastically. I use logging software and I can measure air/fuel, MPG, fuel temp, Intake air temp etc etc it is pretty trick stuff!
