Reading online now about proper burping procedure. It appears there is a strong probability I have done that wrong every time I've added coolant.

 

On my car with a reroute, I leave the car level. I pop the radiator cap off and fill it as much as possible. Then pull a heater hose and fill it till the air is out of that end. Then a turbo coolant hose and do the same. Then reconnect, top of radiator once more, and there is no air.

What kind of front ducting? I didn't find any pics in your build thread.

Speaking of that, is your Turbo heat shield same stuff as your tunnel shield, but double layer: adhesive sides stuck together?

 

I have the oem ducting, i do have a large and a small spall fans on it, it may be wrong but i belive that the reason it does not overheat is that i have a small line with a 1/16" hole between the head front water neck and the line going into the radiator , it allways beeds any air at the top of the coong system into the rad where it can ho to the expansion tank ( i will get some photos when i get back home on Friday)
the turbo blanket is a dei aluminum ceramic aluminum material that i stiched together with safety whire.

That's awesome! Solid posts.

Cats incoming when I get to a computer!

 

That's very interesting on the coolant setup, I may have to consider something similar if a standard burping does not help.

Also appreciate the heatshield info.

 

Here is a flow diagram, i put this on Sahabs turbo car to solve the traped air on his coolant rr system and it sotopped having overheating issues, also put it on two of my cars with FI and coolant rr systems and neither would overheat on the street with ac or in the track.
No guarantee but it has worked for me

 

It was great meeting you today man! Hope your flight home goes well!

 

Very nice meeting you as well! Looking forward to seeing more about your car in the comings months.

 

So as those of you who followed the "almost running out of e85 on the interstate" saga in the chat, I have had to drive the miata this past week due to the electric water pump going out on the 335i. I believe I have found the culprit. Found pieces stuck in the blades of the turbine on the pump.




(Should look like this)

 

So ... it dissolved? Dried out and crumbled? What happened to that hose?

 

It has some sort of hard rubber/plastic adapter with an O-Ring that actually attached to the block with two bolts. It appears that broke. I ordered a billet replacement for that portion, and then you can use the same hose with a clamp.
