    BMW Water to Air Intercooler. What you guys think?




    This is IC from BMW X5
    It has 2 of these on a twin Turbo 5 L motor so each one covers 2.5L

    Thinking of using it on my RXP

    Pros?
    Cons?

    For what it's worth; If I owned that intercooler - I would certainly install in into my ski before I'd purchased a different one. It might be difficult to mount and pipe it tho.

    Let us know how it turns out.

    Oh, that's right - your the guy who bought the crusted up project ski.

    From what I can tell you've got some skills tho. Looking forward to some pictures of what you come up with.

    Good luck!! You have a hard work with pipes to connect/install it.

    You'll just have to make sure your hull is flowing decent air? Other than the random piping, I bet it would work....

    One thing to keep in mind using a typical car air to water intercooler setups is that the IC is usually not designed to handle the very high water pressure that we get on our skis. Most car ICs use an electric pump and a small reservoir tank for the liquid, and it generates very low water pressure ... which works fine on cars, but our skis often generate 60 psi water pressure into the IC, and I have wondered how high the spikes are when we go WOT from idle ... might be higher yet.

    So my main concern would be if the IC can handle 60+ psi water pressure. My guess is that most car setups cannot and the IC might swell or split and leak water.
