Water cooled turbo without water (Merged 9-8) coolant lines oil

[JoeGSX]

Just seeing what everyone opinions on the use of water lines on turbos.

 

[Awdboost]

All The coolent does is help keep the oil from getting too hot and blocking off oil passages. But if you turbo time and run Moblie one you should be fine with out it. FP said it really doesn't make that much of a difference.

I feel with a BB turbo watercooling is defnitley needed.

 

[NosLaser]

It's like this. If your car already has the provisions to run a water cooled turbo (which the DSM does) then if you have the option of running a water cooled bearing housing, go ahead and run one. The reason? At this point, it becomes more work to block off the existing lines. You can definately run it either way, it just depends on how much work you want to do.

I say yes...IMO it does help...whatever I can get to help it I would do it...NOw that I have chosen to go with a L1R now which I should have in like 1-1/2 weeks...I will be happy to watercool it to...

#1 Do not run a water cooled turbo without the water. It's designed to get it's cooling from the water it's not just and oil cooled turbo with extra coolant.

#2 I don't really care for water cooled turbos. Just a bunch of extra plumbing for no reason in performance applications. The OEM's wanted it because it may make the turbo live an extra 25,000 miles or whatever. For us...pointless.

#3 I had a BB turbo that was just oil cooled. Beat the crap out of it, but always cooled it properly. No problems or signs of wear. In fact that turbo is now on another motor and still going strong.

might as well
all the plumbing is there, and there are two nice big gaps in the bearing housing just waiting for your sweet sweet juices

 

[Defiant]

What payoff could there be in NOT watercooling it?

Hey guys, I have a water cooled 60-1. And i was wondering is it possible to take off the water lines and just run the oil. But with out modifing to much or what would need to be done. It is a regular bearing not ball bearing or whatever. Thanks

 

[oldman]

If a turbo was design for water cooled then you should water cool it.

 

[Defiant]

Bad idea, but many do it. To what end, we never hear. But if you do make the change, cool it a lot before shutdown.

 

[FireyIce01]

Basically the only purpose of the water cooling is to cool down the turbo... duh! But seriously you can run it like that, it'll be fine - but if you do, I highly reccomend getting a turbo timer, because if you want it to last, you need to cool it down every time you drive it... that's the other reason they water cool turbo's... so the daily driven car can just be shut off and it won't ruin the turbo bearing.

 

[hybridkid]

The car is turbo timed every time i drive it. So If i take it off it will be ok. But thanks guys

More to keep it cool than to "cool down".
But as you say, "duh".

A water-cooled spool is arranged so that the water takes away most of the bearing area's heat. An oil-cooled spool does this with a greater oil supply and more oiling area. Removing the water and replacing it with air isn't the best of ideas.

 

[hybridkid]

Is there a place that could make it oil cooled or a mod that i could do. Thanks Jay

 

[gasguzzler]

I agree with Defiant.

At least on the water cooled turbos I'm familiar with, they have a restrictor fitting in the oil supply and get MUCH less oil than the oil cooled center sections. I highly recommend water cooling if the turbo was originally designed as such. No, the turbo probably won't fail right away, but it's life span will be much shorter.

What do you have against water cooling? If the lines are on there now just leave them there. Even if you're having fitment problems, it would be easier to fab water lines than to change the center section housing if that's even possible.

 

[Gamble97]

So from my understanding the stocker t25 is water and oil cooled. I'm upgrading my turbo to one that's only oil cooled.
Should I cap off the coolant lines that were there for the t25 OR can I just connect the two to each other? <-- Would there be any downside to this?

 

[bmwisthekey]

I would just connect the two water lines together.

 

[diablos991]

since water is just running in the turbo from one line and out the turbo from the other. I would suggest connecting them. If you capped them, I would imagine that it would impede the flow of coolant.

 

[JayRolla]

Yea I agree connect them if you can. Remember to cool the turbo everytime before shutting off even if not ran hard.

 

[Gamble97]

Yep, I got my turbo timer in as well.
Now all I need is my motor back from the machine shop.

Thanks guys for the help

good luck to ya
