    Intercooler... leaking or not?



    This is a video taken after 20min ride, (blowed all the water out of the IC before the ride) the ski is on the ramp but strapped to the trailer, I put it in a sport mode and it took around 3min of reving it to around 4000rpm to clear the all the water out of IC.
    I'm not sure anymore because my buddy has two more skis and it looks about the same (on all three skis). We ride in cold lake Michigan with very hot and humid weather so to me condensation is not out of the question.

    Is it even possible to be sure if is leaking w/o actally pulling it out and pressure testing it?

    I think that it would take some pretty Extreem conditions to create that much condensation. I bet you can take a few temp and rh readings to find out if the ic is actually condensing the incoming air.

    Not sure what it was exactly yesterday when I took the video but it felt same as today. Now in the late evening we got the air temp in the upper 80's humidity is above 70% the dew point is 69 the lake temp measured by Chicago CRIB... is 63deg! (Lake temperature here depends on winds and currents and varies frequently by 10deg)

    Remove all the water from the air tank with some sort of suction pump then repeat the ramp test. That should give you a more accurate answer.

    There has to be an equation to figure the condensation thing out. I usually get it on tail waters from dams. Water 48-52 degrees outside temp 75-80 degrees. Haven't tracked the due point but I'm sure that's a factor. I'm on a yamaha but the concept is the same. Have had this happen on stock ICs and aftermarket ICs on those same waterways.

    One thing I found that helps is to put a ball valve on the line to the IC and cut the water feed down to half when in those conditions.

    at those conditions it would condensate. but im sure the ic temp isnt the same at the incoming water. the question is would it produce that much!? who ever said the ball valve might be on to something. it would be cool to have something that would automatically meter the incoming water based on ic or discharge temp. kinda like a txv on an air conditioning system. Or have a condensation trap in the discharge line. im fairly new to the 4tec world. how often do you have to worry about the ic condensing incoming air?

    I don't think you have to worry much, I'm just trying to make sure that is not actually leaking.
