Cooling Turbo

[Ninka]

Mate, don't waste your time and effort. There is nothing to be gained by doing this.

There is an oil restrictor in the oil supply for a reason - the bearings do not require what the oil pump can supply and I am sure Garrett know what size the coolant holes should be. It is the air charge I would be focussing on, not the piddly little amount of coolant.

I concur with the comments posted - WASTE OF TIME

Look at the actual hole diameter in the turbo itself, and you will find they are pretty small as well.

Further there are cars which run high hp with no problem in this area

I was actually thinking about fitting a straight thru hi flow glove box !!!!

should make a huge difference

Why would they run the bigger holed bolts on the Territory's? They are there to add more cooling. This cars do get very hot and the turbo does not help.

There are 2 cars I know of running 500rwkws+ mine is 1 (1 isn't anymore.......) and they/I are/am using the stocko coolant holes - albeit different turbos but still using the same banjo bolts that came out of the OEM turbos.

My car runs as cool as on the road. But then again, it is hard to load it up when you cannot get traction.

sounds like a very nice car mate.

I only reason I have started this tread is that I have been told by some one who I can not name, that this was a big down fall in the turbo design, and when the Territory's were being designed they were getting way too hot. These holes were made larger to cool the turbo more and this dropped the temp down in the engine bay.

Some one who you cannot name? Please mate....Whats next are you going to try and sell us all turbo timers?.

You do you think you are? Just trying to help you guys out.

Just think if your turbo is running cooler your inlet temps will drop there for when the air goes through the intercooler it will cool this even more, therefore given you a cooler inlet charge.

If you cannot be helped, don't touch it, only trying to help!!!

Some of you guys really need to cool your own heads down abit... maybe drilling holes in your bolts may help.

Okay mate. Do some real world testing. Log some turbo coolant return temps and bearing housing temps before and after the mod. If you can prove it makes and difference i'l happily eat my words.

Dont forget the excessive flow doesnt automatically mean more cooling. Its still take x amount of time for the heat to be transfered to the coolant. Sure the bolts in the territory motors may be bigger but what else differs aswell?

Who is you source? Somebody inside ford? what are the issues he told you about that drilling the holes out to 2mm larger diameter will resolve?

How is increase coolant flow going to cool the air charge? the heat in the air charge is a result of compressing the air not the heat in the bearing housing.

If you really want to do something to help the longevity of your turbo run good oil and change the turbo supply screen on a regular basis. 99% of the turbo bearing pack failures in these cars could almost certainly be traced back to lack of supply due to partial blockage of the screen.

Good idea, Ill run the test using a laser temp, this will not give the water temps or the air temps but will give the temps on the pipes running to the turbo. Also I see if the car runs any cooler.

I'll keep you posted. And the person who gave this out does/did work at ford...

Good idea mate, If you going to use a infra red temp gun see if you can get temps atthe bearing housing where each bearing is mounted and coolant out let temps, coolant inlet temp shouldnt change. oil inlet and out let temps would be good to see as well. You could measure the temp of the compressor housing outlet externally but heatsoak would have an effect on this.

bear in mind the the shiny surface on the pipework may affect the acuracy of the temp gun. (I know i use these almost everyday to diagnose faults on heavy earth moving gear and a shiney pipe gives you all sorts of wired readings.)
