Turbo Water Cooling

Wed Oct 19, 2005 10:33 am

OK so I'm stumped!

How has everyone incorporated the water cooling of their turbos into the cooling system of the car?

I'm having enough trouble just getting the standard stuff back in as I can't remember where anything goes! :lol:

Cheers!

take it from the TB pipes.Instead of running it through the TB just extend the pipes over to the turbo,or if you want to keep the TB heater pipes let it go to turbo then back to TB then exit the TB in the normal way.
I never had my TB ones connected as the samco inlet pipe got in the way so i just joined to 2 pipes together and had no problems with it.

Won't the water be very hot after it goes through the turbo? Would it cool the TB any when it is that hot or could it actually heat it? I have no idea what temps are like for either of these or how the cooling is working, It's just something that came into my head and I thought I would post it just in case it is relevant.

A friend of mine had a turbo kit for his integra type-r tho the turbo had conections for water
they recomented that it was not installed?
seemed fine without it tho.

Aston,

He meant by pass the TB all together, use the pipework (extended) to run to the turbo.

My TB water pipes are disconnected too, no real need in our climate for them really.

Alex,

From what I've heard water cooling is not worth the hassle, oil only works fine.

HTH, Mark.

Sweet, many thanks for the replies guys

Will run without the water sections for now untill I can sort out some piping. Won't be pushing anything to start with anyway so hopefully the blowers shouldn't get too hot.

Think the TB heater is just to improve cold running. You see lots of older cars with an air inlet pointing at the exhaust and a temp controlled flap to gather up warm air in cold weather.

No TB heater for me though!

Len if you could, that'd be awesome. Will send you an e-mail tomorrow when I've had a chance to test my current coil pack properly, but the rusty transformer plates and split casing don't inspire confidence!

Cheers guys!

Alex.

Alex,

It's also about time you got your camera out again

do we really need to use the TB heating in the UK, i know that they are there to prevent freezing of the TB.

Think my drive's gonna be a hive of activity over the next couple of days.

Got the man coming to fit the imobiliser tomorrow and a mate coming over to help with the exhaust system. Then mate one and I are being joined by mate two on friday so hopefully someone will bring a camera!

I'm almost optimistic that it might fire up by the end of the week!

It is supposed to heat it stop it freezing.IMO you dont need it in this country.

I would deffinately pipe water to the turbo,if it has water cooling it NEEDs it and will damage the turbo if you dont use the water to cool it.
They are too expensive to melt for the sake of extending 2 pipes to the turbo.

Ok I undertand now, sorry. I didn't realise it was for heating the TB.

I know the Mitsubishi Evo turbos have water cooling but a lot of the guys that race the early ones disconnect it to stop the engine overheating. The earlier Evos didn't have quite as a good a cooling system (radiator, intercooler, etc.) as the later ones so the engines could get a bit hot when used hard.

Someone also told me that it is only really necessary if you don't let the turbo cool down properly before you switch the car off. I don't know how correct that is?

the coolant on the throttle body is a economy thing. the design warms air as it passes the throttle body to get the engine up to running temp sooner.
