Thread: Letting the puma turbo wind down

HI Muzzy, in my opinion that is very good practise, especially if you have been driving fast or otherwise working the engine and everything is hot. I give mine about 15 seconds but a little longer won't hurt. Cheers, 130man.

Good idea, on not a long period of time.

Often discussed based on driving technique - eg. take it easy as you arrive at destination to help cool the turbo down (last 500 mtrs is often enough).

If towing hard / working hard / hot weather then a little longer wont hurt.

Often 10-15 seconds is all it takes in normal driving.


When all else fails, read your manual - it should say something.

Our work LV's (TD HiLux) just get turned off: no-one cares and they go a good 150,000km without problems.

This has been discussed in days gone by and the consensus was that 10 secs is generally enough.... any longer and you are just glazing the bores....

But yes it definitely is a good idea to give it a little time before shutting down, especially if you have just come off the motorway into a servo or something...

That's why they invented 'turbo timers', don't know if they're legal any more though ?

Deano

YES.

It also gives time for the rest of the engine to stabilise (temperature wise) especially if its been working hard.

For a car turbo, "any" amount of time is better then none. I used to drive the last lap quietly, and idle for 30 seconds or till the Wife complained, whichever came first.

The habit has stuck, can't do a 'zero-zero' landing anymore...

I have just sold my diesel freelander with 270,000km on it and it was always just turned off - never hurt it. Usually just turning into my street and then into the drive would have been enough for it to wind down.

They have never been legal.

And were from the dark old days of rubbish quality turbo units and poorer grade oils.

They're also a waste of money .

Take the last leg gentler (not slower)
Pull up
Turn on park brake
Undo seat belt
then turn off vehicle.... Open door and get out...

Thats all it needs!

Turbo timers themselves are not illegal last time I checked. What is illegal is getting out and leaving the car while it is still running. So bit of a waste of time, you may as well just sit there and wait.
