Thread: Turbo Timer

Hi Duff, those same companies will also tell you that using the wrong oil will do as much damage and is probably responsible for more blown turbos than not letting the engine cool down.
But of cause, you can put a turbo timer on your vehicle and it will stop your cheapo oil doing any damage, it will stop your battery from going flat, it will even stop you getting piles.
My point is not that a turbo timer will not work, the point is that on the very few times that you need to cool the engine because of hard driving where you could just simply let it idle on those rare occasions, just does not make them a needed device.
If you are a serious 4WD driver, you will know on those few occasions, when you have to let the engine idle to allow the turbo to cool.
If anyone out there who does not have a turbo timer on the vehicle, lets hear how often you have to actually sit there and let the turbo cool.
If the manufactures were genuine, they would put something on the vehicle in the first place.
As in One_Iot’s posting, they want you to idle for 10 seconds.
On this point a I am not sure that it is to cool down the oil or just to make sure the turbo is lubricated properly before you stop the engine.
But if it were a problem I’m sure they would do something about it.
One_Iot, does it say why to let the motor run for 10 seconds?
Cheers

Can't really think of an instance when I HAD to let the vehicle idle before shutting down but I can think of plenty of time when I have let it idle for a minute or two before shutting down, but then again I do that with just about any engine I own. Letting it idle for a few minutes allows the temperatures to stabilise a bit (esp air cooled stuff). Generally I find that my style of driving caters for most of the cool down period, down hill run to home - stop in driveway - open garage - idle in - let kids etc out then shut down. I dont know that there are too many places where you couldn't adopt this method.

If I stall going up a hill or somewhere then I try to start again as soon as possible.

Hi Bushie, ignoring the for and against in these treads, would you consider having a turbo timer installed.

No I dont think I would bother, If I've really worked it hard up to shut down I'd just let it idle for a while, cant see the point in spending a lot of money when I can do it myself for free.

Thanks for the reply Bushie, I think I have steered this thread the wrong way, so I’m not going to say any more other than, a good driver can achieve a better result than a turbo timer. Mind you, Bushie I think, actually I know you look after you motor a dam site better than I look after mine. Any way Cheers and Regards all. 8)

The way I understand it, the 10 seconds is just to let the turbo stop spinning. Turbos can spin upwards of 30,000 rmp (don't know how fast the LR ones spin though), so it needs at least 10 seconds while it still has oil pressure to let the thing spin down to zero.

Longer idling periods to cool the turbo down are not as neccessary as they used to be, because modern turbos do not run as hot as old ones, and with better quality oils, there is less chance of the oil left inside the turbo "boiling" or "baking". However I believe it is still good mechanical handling to allow an appropriate cooldown period, commensurate with how hot the engine is, and how hard it has been working. This can either be acheived with a timer, or simply by being patient enough to sit around for a minute or two when neeeded.

Thanks for that Timmo, learn something new every day.
Cheers and regards

That's the way I understand it too.



Don't tell me I'm right for once - my fragile feeling of self-loathing may not be able to take it. :wink: [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img]
