    I'm running a 20 plate with 3/4 female fittings.
    Water is routed inline after intercooler. Will be splitting the water routing over winter.

    I split the water after strainer and dump the ic water overboard because I do not want high psi in the ic and the heat exchanger dumps into the exhaust
    Sayers how do you like the et 70-145, keeping the slip adjusted

    If you plan to use 1 single line, 3/4" size....use a 30 plate unit, routing on the attached picture...

    If you plan to SPLIT the line, do it after the strainer, and use either 16-20 plate HX that gets water from the IC, and then dumps out the hull...

    IMO one line is a good way to split a IC.. why not dump it after the IC

    10 hrs was still at 19ft.lb. I don't see it as an issue whatsoever. Would take 30min at the most to pull the charger, check slip and re-install. So the maintenance does not bother me.

    So we are all keeping it real mine is an early one and it's more like 70-143. Art had to shave some off an impeller to fit my housing. (had to replace the wheel after sucking up a hose clamp).

    Nice work Danny.
    That's how mine is plumbed. While it is the most efficient I don't think you need to be overly concerned with counterflow on the HX, route your hoses the neatest way.

    So what is any different running it that way or with a stock IC???The water routing Danny uses is almost the same routing Sea-Doo uses on their setups...no IC issues there...Also Danny has monitered temps and pressures and has found this to be the safest setup on a 30 plate HX....

    As i have mine plumbed the same as yours, i was after optimal IC cooling and wasnt/isnt worried about IC pressures to much as there has been hardly any issues do to the HX water routings....

    You have to counterflow the HX, THATS HOW ITS DESIGNED to be efficient...

    I just pulled up my old temp data from 3 years ago, and when setup the way you see in the picture (again, from 3 years ago)...with waterflow as is, thats the most efficient way............When running water/coolant in the same direction, the exit temp of the water was, on average, 20-25 degrees HOTTER than counter. That put the return coolant in the same temp range as the OEM ride plate.........

    When you run counter run, the coolant drops in temp as it travels through the exchanger...When run the same path, coolant will heat up the water, and travel with it until it leaves the HX.......

    Been there, done that, tested, posted

    Negative Ghostrider unless you have a crap IC.
