Yes, and no. The kit on our website is the basic kit. The one we'll be adding has the additional tees, nozzles, etc.

I definitely understand that you need to run distilled water only, but like I said, that's available anywhere and it's cheap. Meth mixes aren't.
Another consideration is the fact that meth is a fuel so *I believe* you have to tune the fueling more than with just water. With multiple maps this may not really be an issue, but I strongly prefer simplicity.
I do realize that you don't have the added power potential when you run just water and no meth, but my goal with a water injection system would be safety margin, not additional WHP. But that's just me.
In any event, congrats on the awesome build!

Yes, injecting water does lower IAT, but meth does it better. True, water has a high heat capacity, but methanol evaporates faster and it's the change of state from a liquid to a gas that absorbs lots of heat (methanol boils at a lower temperature than water).
You don't necessarily *have* to tune for it, but it is beneficial to do so. Anyway, water injection is perfectly fine for what you want.
So, when are you going to be doing this build?
