I am running the last few lines to finish up my turbo install and want to run my turbo coolant lines... I eliminated my heater and bypassed the heater core by having the coolant loop as you see in the pic. What I want to do is pull those hardlines off of the car and weld an AN fitting on the ends that the hose that is looping them is hooked to now. Then I could run the AN lines through the turbo. What I want to make sure is that this coolant is flowing all the time and that it will provide sufficient flow to cool the turbo... I think the answer is yes but wanted to check. The dashed lines represent the proposed lines and the arrows point out the spots I would mount AN fittings. Thanks

i dont see why that wouldnt work. i say go for it

 

I was going to ask this same ? as soon as my turbo came in. looks good!

 

Looks like you are going hard core with removing the entire A/C and the heater core.

SO here is what I would suggest.

Tap the lower radiator hose
Using a bosch water pump; pump water to the bottom water inlet on the turbo
pipe the top turbo water outlet back to the top radiator hose.



This provides the most cooling you can get short of running an independent water cooling circuit with its own front mount heat exchanger.


If you cool the turbo this way make sure to get the water lines going into and coming out of the turbo as vertical as possible, and try to keep the changes in the height of the outlet line going back to the top radiator hose as minimal/constant as possible.

What this does is even after the car is turned off there will be a natural water flow induced by the thermal gradient in the water.


When cooling a turbo with water you need to look at two situations.
One is when the car is running and one is when the car is off.

Before I decided to go with the SOT Supercharger I looked at turbos and came up with some nice ideas on how to maximize the turbo life.

This is just one of them.

An addition thing that can be looked at would be to use a turbo timer to continue to run the water circuit even after the Car is parked .

The Bosch pump only pulls about 7 amps during transient start up conditions and about 3.5 amps when running with a full head pressure. So you could run the pump for 10 mins after shutting down and not affect you ability to start the car next time.

 

how would you tap into the rad hoses?

 

any ideas on how to tap into the rad hoses?

jay, the way your looking at doing it should work fine and it would still allow you to bleed the coolant system at the rear line. and it would look clean.

 

yeah its pry how I will do it although the pump idea is a good one. How is your car coming?

 

slowly but surely. i'm going to be at the shop all day tomorrow playing with wires and the soldering gun. fun fun fun
