Turbo water temps ...

[ranj]

Now the summer and hot weather is here everyday my car runs slightly hot when given big boost... i am running a gt28r roller bearing turbo and its this that is heating the water so much and causing my temps to rise ... i have a double capacity rad to fit yet .... not sure how effective that will be ... When i let the car cool down and switch off i still can hear the outlet pipe from the turbo cooking the water .... Where does the water flow after the outlet from the turbo .. ????? Water pump and then into Rad ????

Is it normal for these turbos to really heat the water up ????

I doubt the turbo is heating the water that much. I think it's just your cooling system being below par.

depending upon which cooling circuit you have the return is either to the header tank, or to the water pump.

i run a GT28RS on an F7P and the coolant hoses to the turbo are forever boiling when i turn engine off, sounds like a kettle! :laugh:

been doing it for over 3 years now, no ill effects.

Ideally a secondary circulator should be used when the engine is off. This should combat heatsoak and prevent the water boiling which comes with its own issues.

clios come with aux water pump that comes on automatically, problem is the sensors in the stat housing and the hot waters in the turbo, so it doesnt know!:rolleyes: :laugh:

may relocate the sensor :)

It really does boil the water that much when you switch the engine off .... when running on the road the temps go upto the 11 o clock line and when off boost ... drop down to 10 o clock line.

Saw a car at the pod day running the same turbo but he had disconnected the water side of things and just relied on the oil to cool it. He had no cooling issues since dissconected......He was running 15psi ..... I run 20psi and didnt really want to go down that route as i am unsure as to how safe it would be ... dont wanna screw up my expensive turbo !

Would dissconecting be a very risky move ???

If so i will have to run a small rad between the turbo outlet and water pump to help while im driving on boost ..... What type of circulator pump could i use to help move the water when not running ?
