LS1 coolant flow - liquid cooled turbo?
OK, so I've seen contradicting information on the internet and looked at diagrams that say different things. I need the real answer... I have water cooled turbos and I've got my feed T in the line going to the heater core. I want to return the coolant to the pass side head. If the t-stat is on the inlet side of the motor, this should work shouldn't it? If it's on the outlet side of the motor, then I won't get any flow until the t-stat opens? Is this the right idea? Should I return the coolant somewhere else? TIA

Coolant flows out of the head, thru the block, thru the pump casting (not thru the pump) and to the heater out port...
the pressure difference between the heater out and the head would be almost zero so you would get almost zero flow...
(i.e. heater out and head are on the same side of the pump)
the pressure difference between heater out and heater in (sees pump suction) is significant, you will get flow if you plumb here;
(i.e. you want two points that are on opposite sides of the pump).
Take a look at this flow schematic I drew:

I have tapped the top of my water pump right above the section for the upper hose and am using this as a feed and the lower passenger side radiator as the return. Does this mean I have 0 flow until the thermostat opens?

Bump for this, I'm in the same boat. I'm thinking about splitting the heater core hose and routing the pressure side thru the two turbos then plumbing the return into the other end of the heater core hose I split for the return. I'm just wondering if this will be too much pressure and not flow enough thru the heater core. They are -6 lines. What do you think?
