GTM Stage 2 S/C on Meth 507whp/357wtq

Just to be clear, my understanding is that injecting water should improve knock resistance and lower IAT as well as allow you to (in theory at least) run a leaner AFR since you can replace fuel with water for cylinder cooling. Water has a significantly higher specific heat capacity than any sort of fuel which makes it phenomenal for cooling (as compared to say gas). 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!
