TURBO MAINTAINENCE

[FPV 521]

Hi,

The XR is the first Turbo car I have had and I just wonder weather you guys can give me any tips as far as looking after the bolted on snail.

I have had people tell me I should let it idle for a time after a work out as it is good for the turbo, also heard that the wrong oil in the engine can bugger the turbo.

Also what are the main reasons why a turbo will blow up and have any of you guys done that. I was told the turbo was very good quality and that I shouldnt have any problems with it down the track but you know what salesmen are like

Can you guys help out please.

Gavin

Although I don't own a XR6T (yet), all my cars have been turbo's, and the first thing I buy after getting the car is a turbo timer. They are invaluble no waiting around in the car after a spirited run waiting for it to cool down, and they (if you get a decent one) automatically calculate how long to run the car for dependant on your driving style.

with regards to oil if you are getting it serviced at a dealership you would expect them to be putting the correct oil in. I always use premium fully synthetic on my cars ( I have found motul 8000 to be the best).

The main thing with turbo's is to change the oil regually most turbo cars recomend 5000k's (not sure with the XR) as the oil doesn't last as long due to the heat incurred in cooling the turbo down.

I would assume the owners manual would have the type of oil recomended by ford, listed in it somewhere.

Unless you've been giving the car a flogging & need to pull up just after, there is no need to idle down these turbos!

They're Roller Bearing, oil fed, water cooled turbos, and really there isn't much that can go wrong!

The main culprit for stuffing turbos is old oil, obviously ford have done their research & know the life of the oil in day to day driving!

In saying that if you have powered up your vehicle, you should change the oil more often, (between 5-10,000 k's) as you now produce more heat which will effect the oil!

hey mate... there are heaps of really detailed threads on this subject... no need for turbo timer as the turbo is feed oil after switch off by some flash hot vs cold water system that goes beyond my understanding but that's what these guys said and I for one trust the knowledge on this site more than a ford mechanic... but it is advisable to let it idle for a min if you have flogged it just before you get home , after a few laps of phillip isld or a drag run...

oil fed, water cooled turbos,

Forgive a newbie question, but could you explain a little what that means. I have been told about oil under pressure supplying turbo bearings, but how is the water used? Is there a water jacket that is used to remove heat from the bearings or something?

good advice although I use german OWS oils not as cheap as motul though OWS comes in at $25 per litre awsome stuff

This is cut and pasted from another thread as I dont know how to link... please forgive me...

Ford used the thermosyphon trick..how it works simply,turn off donk,turbo hot boils coolant,boiling coolant rises up the pipe which means new coolant flows in,so you get a flow of coolant moving around and around with out the water pump running.

Pretty neat trick that,good for around town stuff.

If you do a track day and sting the living sh!t out of it,you should let it run a bit before shut down

Cool that answers a question I had as to why ford havent documented anywhere the need to let the turbo idle after some hard driving.
