WI vs IC
You can make more power with WI at the same boost easily. I made the same power at less boost on a car with it vs without.
I think anyone not running it is crazy. Leaving alot on the table.

And it's not intake temp cooling that makes it effective. it's combustion chamber cooling. you really don't want to drop your IAT under ambient; it could cause water to turn back to liquid in the intake tract and collect.

While an HSV will allow for great tuning, I don't think there will be much gain over a dialed in progressive system and I am not sure whether DO has plans to release one. They have a few other more important products they are working on that should be released soon..
I certainly wouldn't be running without at least a basic system in the mean time.
You don't spray pre FMIC.
My little bro installed a basic system on an Audi S4 today. The phrase that kept being repeated was" It feels like a different car"

I understand the concept of evaporative cooling. Bear in mind the intake charge temp is well above ambient.
the primary purpose of WI in our application, meaning forced induction device pushing hot air through an a:a heat exchanger, with the WI nozzle near the intake manifold, is not so charge cooling as much as it is knock control via combustion chamber temp cooling.
read through aquamists' tech pages. good stuff.
WOT, the HSV will do more for me than that. Consider it will allow me to control the squirt event based on a 3D map (MAP, IAT, RPM). It will also allow me to have only 1 controller in the car (and not have to have a seperate box). Since my controller is a fairly capable ecu, this means I can fully control, monitor, and datalog the amount of spray. It would also mean I could add a WI gauge to MLV and have it appear on my palm. Screw a red LED, I gotta gauge NGA.

With Devils Own's new nozzle coming out that produce multiple droplet sizes, evaportaion and heat absorbtion will be happening all the way to the chamber from where ever the nozzle is.

Yes the below amnbient cooling lowers our BSFC and given the velocity of the intake tract what is not evaped is suspended in small droplets. Kinda like a swamp cooler. Haven't you ever been to a amusement park where they spray water through a fan at people, and notice the cooling effect you get from that. Most would argue this is do to galvonic skin response, but the increased evap do to surface area increase and the calorific holding power of h20 and methanol.

Al, I should have something soon for you. The car and setup will be
90 Miata 1.6 with 60k Miles
Flipside T3 Manifold, T3 S60 with .48 hotside.
2.5" DP and 3" exhaust
Pretty large FMIC with Flipside plumbing
Devils Own Basic system with 3 GPH nozzle.
After his first drive at 15 psi and making no tuning changes he swore he gained 25 whp. I guess we will see on the dyno. He also has spiked 22 psi from a wastegate signal line failure. He checked his logs later and had no knock sensor activity.
