    Water routes with External IC, what is concensus

    I have an external intercooler.
    I have the capability of having 2 water lines (stock and one from pump) and I have a pisser on the side of the ski.

    I use to have split water ways one going to the IC then a pisser.
    The other stock one going to the engine/exhaust.

    I've lost 2 superchargers from the 2nd line from the pump loosing flow (different reasons).
    My major requirement now is I need some sort of alerting if water to the IC faults and it's a no brainer if someone else was riding my ski (kids). I had a cheap temp alarm which just had a sticker external probe. It ran out of batteries when my last IC explosion happened...


    I've also tried doing a T fitting from the stock and it didn't provide very much flow or pressure to the IC (put both meters on it). This was using the stock yellow washer on the pump.

    I saw the groco install in the How To and they were doing T fitting after the groco. I've tried this before and unless you open up the washer you aren't getting much water flow.

    I've now gone to stock water going to a groco (with arrow pointed in right direction) to the IC and the IC exit going to the engine/exhaust.

    This will let me get a "overheat" alarm if I get a water pinch or lack of flow but I have a little warmer water going to the engine.

    I've thought about opening up the washer and doing a T fitting (I think I tried this already). Thought about also running both my separate water lines into one big one then splitting it into 3/4.

    I know water travels to the lease resistance.

    Use your opas feed line for your intercooler and leave your pump incoming line alone for your exhaust. Your opas fitting has a screen in it to help with debri getting into your intercooler.

    IMO only use a water strainer for the IC only

    when it gets plugged (it will one day) you will only have high IAT
    and not have a melted exhaust

    This is what I thought was the most efficient, however when my filter clogged up and I had a slight pinch in the opas hose inside the ski it ended up overheating my IC and blowing a core then the mist blowing up my SC. I'd like an alarm somehow if the flow minimizes.

    This is what has me leaning toward having the exhaust inline because it will alert if too hot which has me leaning toward modified washer and either T or inline..

    Don't want to loose my X charger now...

    the IC can not damage a SC
    also you can not over heat a IC
    yes you can get it very hot, but it will not hurt it
    what will damage the IC is too much water psi (like from a pinched hose)
    also when the IAT sensor sees very high intake temps the ecu should cut timing or throw a error code

    So you can run an intercooler with no water and nothing happen ??
    I believe the SC can push about 200 degrees air right ?
    What if you had the intercooler with no water for 20 minutes with SC pushing 200 degree air and the metal was then around 200 degrees then 70 degree water went through it ?

    The core would handle it ?

    aluminum melts over 1200*
    so 200* isn't shit
    what destroys a IC is excessive psi or corrosion

    I have 6 skis running water from the pump support plate to the back of the intercooler out the front-- feeding the exhaust. A bleeder out the top to fill the intercooler and an identical fitting used as a "dump" to clean out any sediment that may be coming into the system to prevent core contamination-- this is at the low point of the cooler. The bleeder and dump are y'ed together and exits the rear at a 45 degree angle as a monitoring feature. The water is filtered with the stock oem filter of the pump.

    This setup is very simple and has worked without issue on my skis that have ran up to 87 mph. Keep it simple...

    a lot of sand goes though the stock "filter"
