hey guys, before I make a hole into the upper radiator, I just wanted to double check whether the following would work.

I think the coolant nipple on the driver side of the rear iron is supposed to be output going to the heater core. I don't have heater anymore, so I had capped off. I plan on using this coolant outlet to cool the turbo core and return the coolant to the upper chamber of the radiator.

would this work? thanks!

 

Would it function yes, I take it you have an EWP

 

I currently have it returning into the throttle body return nipple on the water pump housing, and it looks bit messy. I just wanted to clean up the bay little while I wait for a dyno time.

 

Ideally it would run to a low pressure port on the pump inlet.
This would promote better flow past the hottest part of the cooling system.... the spark plugs.

The downside would be introducing hot water beyond the radiator so some type of small radiator would be required.
Maybe an aluminum trombone like the power steering cooler.

 

that sounds overly complicated just to increase flow. I can always add inline EWP to help out if flow is the issue. I don't have issue with cooling right now, but I bet the line size is the bottle neck for most. My lines are only 1" because those AN fittings are so darn bulky..

Now if you suggest having a separate water cooling system for turbo, that may make sense if you're having temp issues.

I was thinking of going air-to-water intercooler and water-to-oil heat exchanger to clean up the bay little further. it would also allow some clearance for cold air intake rather than sucking air right behind the radiator.. but I wonder if 26x19x3 inch radiator can keep up with all the extra heat. has anyone done this successfully for street driving in a hot climate?
