Our Answer to running Coolant Lines

Re: Our Answer to running Coolant Lines
All I;m saying is that coolant does NOT flow through the rad when the thermo is closed. We can all agree on that. The coolant would have to wait for the thermo to open to allow flow. I was thinking a good place for feed would be the front drain hole and for a return go after the thermo on the housing. This ensures that coolant is flowing at all times.

Re: Our Answer to running Coolant Lines
I would think going to the top of the rad would be best since the water pump is already flowing the coolant inside the block/head. The coolant comes from the waterjacket via the large drain bolt to the turbo to the top of rad so that it can drain back into the head since the top rad hose is connected to the head.
Or maybe draining into the bottom of rad is okay since the additional coolant from the turbo drain will cause overflow on the top of rad to drain into the had via the top rad hose.
Either way that is a clean setup and would seem to work.

Re: Our Answer to running Coolant Lines
I said nothing about boosting and operating temps in my post. When you car is at operating temps the thermo does NOT stay open at all times. So what your saying makes no sense at all. What your saying is that you should only boost when the thermo is open, right??? C'mon now..

so my logic isnt "boost when the thermo is open" its more like the thermo is open at operating temps, therefore your turbo should have coolant flow at operating temps when you begin boosting.

Re: Our Answer to running Coolant Lines
If i read that picture correctly, you have hot coolant coming from inside the block, through the turbo, to the lower end of the radiator?
You do realize that you're putting hot water into the cool water thats flowing into the engine, thus weakening the cooling capability of the radiator.

Re: Our Answer to running Coolant Lines
I like the idea of putting two bungs on the radiator. One on the bottom that feeds the turbo and then one at the top for the drain. I see nothing wrong with this one. Don't have to wait till the thermostat opens at all. plus you are putting the used coolant in the radiator and then getting it cooled and then it gets fed to the turbo through the bottom.

The water pump is the source of pressure in the system, in order to cool the turbo, coolant that is moving, before the thermostat, must be plumbed to the inlet on the turbo, then from the exit, you need to find a place to releave the presure and send the hot liquid to be cooled down again before starting the cycle all over.

Re: Our Answer to running Coolant Lines
What about this:
Have a -6an bung welded to the coolant pipe on the back of the block and then have a line going to the turbo as a feed line
And then have a -6an bung welded to the bottom of the radiator as a drain source?

Re: Our Answer to running Coolant Lines
The only thing I think is wrong with the Synapse sytem is the return IMO. I would prefer to have the return on coolant pipe on the back of the block right by the water pump.

Re: Our Answer to running Coolant Lines
Is the D Series Freeze plug the same size?
Turbo D gets no love. All these coolant lines are advertised for B series.

Re: Our Answer to running Coolant Lines
I did my lines this way. I left the hose on the back of the turbo off to see if coolant would come out of there. I started putting coolant in the radiator and coolant came out of it which tells me that coolant is moving through the turbo all the time.

Re: Our Answer to running Coolant Lines
i have the same thoughts as stiffdog.
can you feed and return both to the radiator?
i want to feed it off the bottom of the rad and return it to the top.
i am having some slight overheating issues and i figured it would be best if the hot coolant from the turbo dont ever even go to the motor. if its possible i would like to both feed and return directly to the radiator.
