    Nice run. One question though: you hit the I/C spray while you're in the middle of your run sometimes?
    I only do it in between runs, but does it noticably help if you press the button while you're WOT between gears?

    Think about it this way. Wet your hand. Hold your hand steady in the air. Now wave it around. Which feels cooler, steady or waving?

    The latent heat of evaporation (vaporization) is greater with a flow of air over the intercooler. This makes a greater drop in temp for the same amount of water spray.

    Another way to think about it is if you spray onto a hot surface that is just sitting there, you get a steam cloud that interferes with cooling the surface by retaining an area of heat just above the surface. Now if you have a wind to blow away that steam, the surface is allowed to produce more steam, thus cooling it even further.

    just my perspective

    No, i didnt get to hit my IC spray. I would think though that the difference wouldn't be so substantial, but very minimal.

    IC spray when the IC is gettin air across it AND the turbo is pushing lotsa hot air into it? YES YES YES!

    IC spray could very well give ya 30 hp during a run...well, 20 lets say.

    It drops the intake charge alot, that is denser air. It helps with detonation, and the computer will see that and advance timing more.

    I know the newest F-150 SVT Lightening(sp?) sees 50 transient hp with the a/c triggered sc-cold air dump. Thats FIFTY hp, for a period of 30-45 seconds, until the a/c system recharges. Its pretty similar to what a IC spray does.

    I got to ride in one and it felt kinda bulky...I can see why you're glad to be rid of it.
