Cooling Turbo

[hqracer89]

Thanks for the heads up, I'm going to the footy tomorrow so, the first lot of testing can wait until Sunday. I'll try and get the photo up than too.

I don't know why you guys are all shooting this chap down for. He's sharing a modification that he is undertaking, that may or may not benefit us all.

It sounds like a trivial thing, that won't make any difference. But geez, no need to be rude about it guys. Keep an open mind.

Or are you 'old dogs' just not willing to accept that maybe someone else may do something different and introduce something new to the community, rather than yourselves??

I do think that if you can bring the bearing temps down, it will also bring down the charge air temps. Will it be a measurable difference? I'm not sure...

But with a top mount cooler, susceptible to heat soak, maybe Ford have increased the bearing cooling in the territory for a reason? That poor IC could use all the help it could get.

Not Bagging him, Just think at standard or mid power levels is a bit early to be drilling holes in the turbo.

Any way good luck with the mod, let us know how it goes.

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.

OK I'm not going to shoot you down here, but I do think you have been given bad advice, or have misunderstood what may or may not be achieved.

Cooler engine bay - I think not!!! Stop and think about it for a second........ You have a small tube supplying only the centre of the turbo with a small amount of water, purely to keep the bearing housing below a temperature where the oil will carbonise, which would result in blocked bearing housing on the turbo, nothing more, nothing less.

The small amount of water passing through the housing (even if you were able to increase the flow by 50%) will have absolutely no impact on engine bay temperature.

The issue here is if the standard cooling system is doing its job, and with the right oil, the answer is yes, as we would have otherwise seen more failed turbos full of carbon in the bearing housing, something which is not the case.

Will you achieve more water flow - possibly

Will it make the temperature lower - Hmmmm yet to be convinced

Will it have any impact on longevity of the turbo - Probably not

Hope this helps without offending

I do agree that we should have an open mind to whatever people do, but also that some of the 'Modifications' discussed should be criticised if they are of doubtful benefit, as other members look to the forum for advice on useful things to do to their cars to increase performance or durability, and not all advice given passes either of those criteria.

You won't cool the charge air with larger coolant holes - no way in gods green earth. The air flow is way too quick through the turbo and trust me, the coolant already flows through the turbo bloody fast! I learnt that the hard way when doing my turbo swap...............

Not shooting you down at all but I would really focus your attentions elsewhere way before this mod for much better tangible results.

Just trying to help!

Yeah the water is just to cool the bearings/cartridge, not the housings... it would take ALOT of water to cool the housings lol

BUMP

How'd you go hqracer? did this mod set the xr6t world on fire?.......

Didn't get to do anything on this at all. I have lost the temp gun and they are not cheap to buy. Trying to think of another way to test. I was going to try and use a contact temp gauge but I don't think it will give a correct reading. I have now installed a Process West Stg 2 Cooler and had headsex to do the injectors and the tune.

I think the best way to show that this may help any of us, is to get the temp of the Turbo before and after a hard run. But that's all I can think of at the moment
