    Anybody done or thinking about doing a water/methanol spray

    Don't believe water compresses...might not be good thing for a blower

    Liquids do not compress. Water does expand at a ratio of approximately 1/1600 so a little water would go a long way.

    What was the cause of that supercharger exploding a month ago someone posted from Facebook?
    Be careful and do your homework/research

    Can you let us know the results?

    Water/meth injection is popular for racers that have supercharged/turbo engines. The meth is high octane and cools the air intake...the water is mixed in for safety...cant remember the safe point but around 50/50..

    I used water/meth injection on the 2006 SRT10 I supercharged. Worked well but to get any real advantage you need the engine tuned for it. Mine was and it was good for about 3 tenths off my qtr ET.

    If you have it tuned correctly and the correct nozzles it will add HP..disadvantage is if something happens to the injection system (ie pump) it can cause a lean out condition while at WOT which can lead to a blown engine..

    I did it on my Cat, tried a Snow stage II kit. Had a 50/50 mix, dual nozzles, and it did very little, like maybe 5 HP gain (at best). I took it off, it is on the shelf.

    It is called running the blower wet, when you inject before the blower. HHP briefly played with it on my set up, Josh and Top Cat are not fans of it, I took it off.

    Overall it's a great safety net if tuned properly, centrifugal supercharger applications use it very successfully injected downstream. Pooling may be an issue injecting it upstream though.

    The only advantage I could see is "IF" and its a big if, you are unable to get high enough octane; better to use a Nitrous setup as you get the same cooling effects and the added bonus of more fuel to burn. You still need a custom tune, and cooler plugs with shorter electrodes to aid in preventing pre-detonation.

    I've played with water a bit on my diesels. We rarely used it for power, but the cooling effects were incredibly. Heat soak was eliminated. The water/steam will raise your compression ration slightly and on a supercharged motor, will make the charger more efficient. Will raise boost.

    On a dyno run, not much is gained, but I would bet a road course, there would be incredible cooling benefits.

    I haven't played with it on my car yet, so this is all just from general knowledge and previous experience.

    On our diesels we ran 100% water for cooling.
    At 75lbs of boost, you'll take all the cooling you can get your hands on. Heh
