I didn't want to post anything until I took some pics, but I haven't taken any pics yet
I'm currently running distilled water. I was going to get washer fluid but I need to find one that only has water and methanol in it and no soap. I have a very small leak on one of the threads of the injector. I really shouldn't be running it with that small drip but I am anyway. I need to get some more teflon tape (ran out) and secure those threads.
Overall it is an impressive kit. The injector is a set of brass fittings that allow you to spray along the axis of airflow in the intake. Right now I have the injector facing the throttle body, but I may reposition it so that it injects against airflow. My install is clean, pump and resevoir are in the trunk to keep the fluid as cool as possible. I'm running a nozzle that is rated at 2.3 GPH at 100 psi, and I upgraded the pump to 150 psi. Right now I have the system set to engage at about 3 psi of boost.
First impressions from driving it around today: OMG. Performance wise it feels as if there is no heat soak at all. Can't wait to try water/methanol.
I'll post pics when I get a chance to take some.

Oh man this is kool. Let us know ALL the details and pics of course. I'm so glad you got it up and running so quickly too. I'm off to H-T to see what you said over there..hehe.
I think this will make a much bigger difference on the IAT's compared to the EGT's. Time to do some datalogging to see the difference in IAT temps regardless of heat soak.
Their should be a difference in both. Your adding mass into each combustion cycle, but you have the same amount of energy being released (If you don't add more fuel). The overall EGT temps should be lower.
Isn't water injection supposed to work at normal operating pressures, not just boost? Some of these companies aren't aiming their product toward boosted engines, so is it a matter of metering problems?
shark,
check this site out http://www.dawesdevices.com/howto.html
look under "The water/alcohol mix"
it says to use denatured alcohol since methanol is hard to come by and is very toxic

It seems to be a matter of selecting the appropriate nozzle size for the planned power output. I may actually move up to a 3.9 GPH (@ 100 psi) nozzle.

Usually the denser cooler air will require more fuel and the ECU will react in turn by probably bumping up the timing slightly as well. That's why very likely Shark will get some power out of this as well, esp if he's running ethanol as that's combustable as well vs water which cools the intake charge but takes up compression space and is inert. So it shouldn't be the same amount of energy being released.
Here are a few pics. I'll take pics of the injector parts and how they install into the intake probably this weekend.
Here is the tank and pump mounted in the trunk. Yes, I know my back window is dirty

The injector mounted on the intake. The solenoid and clogged nozzle detector are behind the catch can.

The clogged nozzle detector is just another boost switch with the high pressure water line T'd off to it. It is placed after the solenoid, so that when water is flowing, the pressure is high, closing the switch and lighting an LED I have mounted on my Autometer gauge pod. When the solenoid closes, the pressure between the detector and the nozzle drops, and the LED goes off. If the nozzle becomes clogged, the pressure stays high and the LED stays lit. Simple, but very effective.
I should have taken a pic of the LED on my gauge pod, but my camera batteries are dead now

Hrmmm, since the resevoir is in the trunk, I'm thinking any amount of methanol is not a good idea. I may have to just stick with water. Or I may move the pump and resevoir to under the hood after all so I don't have to worry about evaporating alcohol in the passenger compartment.
