    When I ran closed loop to a Garret watercooled turbo, I took the small line off the head, next to the Large one at the back of the head, and ran it to the CHRA of the turbo, then back out to my watercooled wastegate, then back out to the coolant bottle.

    At high RPMs it would run hotter due to the extra heat generated from the turbo. If you had extra capacity, or a larger external heat exchanger it would work better than the stock setup.

    I have since switched to open loop cooling, and everything stays much cooler now.

    IMO running anything extra on the stock closed loop system is asking for trouble, they get hot enough when stock let alone a tuned motor and then adding the turbo.

    2 options really, add a heat exchanger and plumb it as Psycho has suggested or go over to open loop. If you want to keep the stock closed loop, I would personly run the bleed line from your ICer to the turbo, nice cool water...

    Heres my setup which is for sale due to space constrictions. Basically I run a "t" Inlet One side straight into Intercooler then to Heat exchanger and out the door. The other side cools my Header, and turbo system. Not the best Pictures but I try meh.. I definately go low on thermo and like above said heat xchanger.

    Split the water inlet between your IC and your manifold and that will help temps some. Hell it's better for the IC anyway

    My nextstep will be for sure a heat exchanger but right now i'm running as follows:

    -thermo running open all the time.
    -i run the coolant to the turbo with a "T" connected to the hose that the coolant returns from the oil cooler to the thermo.
    -i drain the coolant from the turbo with a "T" connected to the hose that the coolant flows from the thermo to the oil cooler.

    what do you guys think about this coolant routing??

    A BIG THANKS to you all for your advises and ideas!!

    Not sure how its gonna work with the thermostat "open " all the time. The coolant will get very hot from trying to cool the turbo. Go for a 30 plate heat exchanger, might help some.

    Breon, had a 30 plate HX, and had fabricated a larger coolant tank out of aluminum, that worked ok, but anytime he had a problem, in the hull, he couldnt reach in to fix it till it cooled compleatly. Way too much crap in the hull, from closed loop, and it was all red hot.

    open loop cleans up the engine bay LOTS, and everything stays plenty cool. Just flush everytime u ride...
