You got it Jordo.

Just a little thing I'd like to add about the latent heat absorption of water vs. methanol. While the water has a higher heat capacity than alcohol, at lower temperatures (like those post intercooler), the water won't evaporate as much as the methanol will. Remember that the heat of vaporization is significantly higher than the heat capacity alone. That's why alcohol feels so cold when it's placed on your skin. The liquid isn't cold, it's just drawing a lot of heat from your skin as it goes from a liquid to a gas (thanks to its low boiling point). That's one of the other reasons alcohol motors make so much power: the evaporative cooling from the alcohol drops IAT's well below ambient and you end up with a much cooler, denser air charge so you can add more fuel.

Now, in regards to running it with our Stage 2 Supercharger Kit, we'll be making a post later this week about a project we're doing with water/methanol injection and our Stage 2 Supercharger Kit. So stay tuned for that to get a better idea of what can be done.
