would you add water to my set-up?
~1.9l
8.5:1 static compression
11.5:1 AFR
261whp/252wtq @1BAR
I've considered adding water and leaving the tune where it is just for cooling and safety benefits when running the car on the track.
I'm not sure where to draw the line on safety and being reasonable.

Paranoia, big destroyer!
I thought you already put a conservative afr AND conservative timing in your tune?
How many gallons do you think you would go through during that many hours of boost? Are you willing to add that much weight? Would you run out in the middle of an event? Would that bother/distract you?
I wouldn't give myself another distraction from the other mechanical aspects of the car yet. There are plenty of places that will deserve inspection and attention on your first track day. You probably want to focus on running what you've got and learning how it behaves before adding additional complexity or failure points. If you have a problem with the WI, yeah, it won't stop you from running, but it will aggravate you and cause you additional worry unnecessarily.
I know, I know, it's not like you to worry about things, but try to keep from adding points of aggravation to the mix. It makes it easier to relax and enjoy the moment you have worked so hard to realize.
Enjoy yourself.

I'm the one that suggested he do this yesterday and as usual he questions everything and seeks everyone's opinion. Fair enough. So your argument is it adds complexity and more failure points. Ok. But why don't you think about what you just said for a second.
Even if it fails, it doesn't matter. He's running it to have a safety cushion. The motor will be tuned to run SAFELY without it. The WI just acts as a buffer. Peace of mind. If the WI fails, so what. Why people worry about WI failing so much I don't understand. You could just as well have a fuel pump get weak during a session. **** happens. That doesn't mean you carry 3 spare fuel pumps though.
For hustler, he's not even gonna do map switching or boost changing. All he needs is a simple kit. Whenever he puts the car on the track he fills the WI tank with water. When he gets ready to race he arms the WI system. Now when he makes say 5 PSI his pressure sensor closes and the WI comes on. If you wanted to get fancy he could add another pressure sensor that Tee's into the line hooked to the nozzle and hook that to a light or something so he sees a light when he's got water. Then if the light stopped coming on he'd know something was wrong.
WI systems aren't often troublesome as they are relatively simple. As long as he does a good job installing it he'll be fine and it will do what it's intended to do. Telling hustler about how something could break and making him worry more is not the thing to do.

given that u want this for the track where u will be running 14-20 mins max prob in boost i would go with about a 1 gallon tank and at your power lvl probly a 320 cc/min nozzle at 100 psi. That should be maybe 4-7 lbs for the water tank 2-3 lbs for the pump and 1 lbs or so for the lines etc. so maybe 18 lbs.

I have never really though of WI that way for whatever reason. That exact reason above is why I have never run one on any forced induction, I was too hung up on the " I have to watch the tank and keep it full or I blow up". Never thought about it enough I guess. What kind of time can you get out of a tank (say the washer fluid res.) of water/meth running spirited street driving? Days? Weeks?
Whats a good diy kit/system? Does MS have any kind of output for aux. like WI? I forget.
And wow, I just realised we had a water/meth section... shows how observant I am.

can someone in the know confirm that spraying water (not meth) will lower EGT significantly? The more I read about lowering egt, the more I see that people discuss water and meth synonymously.

I do not see how it cannot. It is just a matter of how much. I'm adding an EGT to my manifold and spraying water so I should have some real-world data in the next month or so once I make it to the dyno. I planned on looking at this anyway.
If anything I would think water would reduce EGT more than meth since it is not adding any more heat to the combustion cycle, just absorbing it.
