PWR A/W IC and water-cooled turbo

[Sandeep]

Hi,

I am starting to plumb up my turbo system for my T4 ... I've got the intake system almost completed, just need to sort out where to place the PWR 4" x 6" air to water intercooler and radiator ... I will sort this out but my question has to do with a watercooled turbo.

I have a TD04L-13T from a USDM WRX and it is oil lubricated and water cooled. Since I am using an air-to-water intercooler, can I run the waterlines for the turbo in series with the intercooler ?

I am making things harder than they need to be ?

Thanks

Sandeep

Sandeep i think it would be a lot better if you ran the water from the intercooler to the turbo since the intercooler outlet water temp would be much less than the turbo.

These are normally in two seperate circuits, the turbo temperatures are way higher than the chargecooler circuit, the turbo circuit is normally at the end of the main coolant circuit.

BTW, what is PWR ?

[Racelook]

Walter,

PWR is an company that makes thinks for o.a. racing cars.

They have verry nice Intercoolers (air-air and air-water)(also the one that Ian Swinkels had used)

The turbo system for my T4 was about 90% complete when I started researching the WRX conversion.



I had a motor lined up and then I got some bad #'s from the owner who had really abused the motor.

I got a quote from Kennedy Eng for a kit with clutch/PP that would handle 300 hp and I thought it was outrageously priced.

About that time, some crazy Scandinavian proved with hard #'s that you can get 234 HP and 258 ft-lbs from a stock 2.0 Bus engine with some headwork and a TD04HL-16T

Well, add these up and you can see why I'm going to finish this T4 turbo

I just ordered my IC today. Looks like I may need a second seperate water circuit for the turbo .... wonder if a 12v waterpump for water cooling home computers has enough flow capacity.

Is not the flow thats the issue, its the temperature range of the liquid, most PC watercooling pumps WONT like the sort of temperatures it would see in this circuit.
Eheim 1250/1260 would be the most likely, but they are mains powered and have a lot of plastic...

dude, you dont have to run the water lines to that turbo at all. i reccommend not even hooking them up. the turbo does not need to be plumbed with water, just oil. Infact, I had a stock turbo on my built car for a while, and i ran it with no water going through it. the one thing you just have to make sure of is that you dont run it too hard, then shut it off right away, the oil would be too hot, and would cause problems.

but seriously dont even run water through it at all.

Yeah, they just spend a bunch of energy to engineer a turbo water cooling system for no reason !

no, they do it so you dont have to idle your car for a minute before shutting it off.

believe me. ive done it and so have many others. with not one ill effect.

Quoted for truth. Adding the water lines to the turbo will add complexity to your install that you really dont need. But I would add a turbo timer to prevent coking the oil in the center turbo bearing section. I would also reccomend running a 5w/50w or 15w/50w synthetic, your turbo will thank you. I run it in my STi powered GC8 and I have heard no complaints.

[Sandeep]

Thanks for all of the feedback. I have to run a cooling system for the PWR intercooler so I thought I would tackle the turbo at the same time.

If I don't need it, then I won't mess with it. :agree:

[volkdent]

Sandeep, where did you get your PWR intercooler from? What size did you get? I had talked to a guy selling them off of Ebay awhile ago that I wanted to buy from, but he's not on now.

Any new progress?

Take a look at the modern Tdi engines most have an electric water pump to cool turbos down VW/Audi started using them in the early '80's

[DORIGTT]

Hey Bobtail,

Aren't those just afterrun pumps? I think they just run for a short time after the car is shut down to aid in heat removal from the bearing housing on the turbo section. They were to aid in thermosiphoning (sp?) to keep coking away.

The Most Audi turbocharged cars use them, Volkswagen (post 98) turbocharged cars with the TDI models starting in 99 or 2000. The VR6 Volkswagen models also had them because those motors ran HOT! They were designed that way, but they didn't want heat soak after shutdown.

Check it out folks.
