Turbo car over heating
To get all the air out of my GTO I pulled it up on those plastic ramps. Then ran it with the cap off until the thermostat cycled a few times and temps got to 208F(heat blowing full hot). A crap ton of air bubbled out when it hit about 205F after the thermostat cycled a couple times. As it heats up, some fluid will overflow and trickle on the ground.

i have a lt1 with a turbo, and it sits very close to the radiator and coolant hoses.
i have to 1000cfm pusher fans, and a radiator similar in size to yours.
i dont have a hod yet, but my car has NEVER seen over 200 even in 105 degree heat, in stop and go traffic.
on the highway, it will never get over 165...
i bet you have a bubble in the system.

hmm, i am also thinking my fans might be wired wrong or something. i noticed it when i bought it but the guy i got them said they worked wired like that for him
there is a blue and a black coming off of each fan, so you would think blue would be the 12v and black would be the ground for each fan, or the other way around.. Well the previous owner of the fans had them pre spliced with a black wire from one fan and a blue wire from the other fan.

it sounds like a bubble in the system. i just delt with these same issues on a large turbo'd cobalt.
we set a large funnel where the radiator cap goes, and filled the funnel up with coolant. we then started the car up and let it run while squeezing the radiator hoses. the extra weight and fluid height of the coolant in the funnel helped push it through the system.

Def. try burping it again. put a hyrdolic jack under fthe front end and jack it up so the rad cap is higher than the engine a few inches, this will help the air that may be in the system travel up and out of the rad. cap.
With the rad cap off and the defroster/heater on full heat and high fan setting. Start the car and let it run it may spew coolant a couple times while it is pushing the air out of the system.
But let the system cycle the thermostat a few times, a 185* t-stat should be better, becuase it alows the coolant to stay in the radiator longer and cool down so while you are burping your system try running a fan infront of your radiator, to simulate driving.
Also do you have a Front mound intercooler? If so it could be blocking airflow to the radiator not allowing the coolant in the core to cool down before being cycled cack into the engine.
Second, I have not seen pics of your car so how is the availibility of airflow to your Radiator, do you have any extra vent tubes made to direct airflow to your radiator. being that you are turbo charged, that turbo will create a lot of heat under your hood.
That being said you will need as much cooling as possible. I have cooling issues with my Eclipse turbo right now, so I feel your pain.
I know most of this was said in earlier post but there was not a lot of explination detail in most of the post. Hope you get it fixed man that is quite a large turbo you have under the hood there lol.
