Turbo Coolant Line Routing
I know it's been asked over and over and there are many different ways, I just want to be clear on a way I haven't seen yet, as simple as it sounds to me....
With my new turbo set up can I just weld two an fittings to my mishimoto radiator, one at the top and one at the bottom? Then just run both lines directly to turbo...I mean this sounds very simple and it seems it would have the best cooling efficiency just because it's pulling coolant from the coldest spot in the cooling system.
I would use the block plug on the back of my Y8 but I will be installing a sandwich adapter with sender units and lines going to an oil cooler and the only way it clears everything back there is if I have it turned in a way that the lines block the coolant plug.

Re: Turbo Coolant Line Routing
i do not think there will be a pressure differential if you plumb them both to a radiator.
you need a source of vacuum on the return. i have it plumbed from the intake manifold coolant outlet and back into the thermostat housing, after the thermostat, where the pump creates negative pressure, pulling the coolant through the turbocharger.

Re: Turbo Coolant Line Routing
There isn't anything in the turbocharger that circulates your ethylene glycol or coolant like a water pump does. If that's what you were thinking.
On my set up I would plumb the lines as Ash said. That would allow coolant to be drawn thru your turbine case at all times the engine is running.
Now, when you turn off your engine, thermal convection takes place. The high heat absorbed from the turbocharger causes the water to move up while drawing in cooler water from its lower water source. This is why most people plumb their lines to take advantage of this benefit.

I agree, take proper precaution when choosing your coolant line design. Here is an 'oldie but a goodie' when it comes to turbo optimization...
