a TT is NEVER required on anything . . . in fact . . . technically they are "illegal" and a number of Insurance co's wont allow them anyway.

Allowing it to cool down though is important.

Hi there all.

This is in fact an urban myth. Most transport departments don't mind the use of Tubo-Timers, so long as the unit that you are purchasing is installed correctly.

For example, the RTA states "No vehicle shall be left unattended with the engine running unless a suitable locking mechanism is fitted, in order to prevent the vehicle from uncontrolled movement".

Tasmanian and Victorian laws are basically the same, just the wording is a little different.

Insurance companies aren't that affraid of them either, except for your mainstream companies, as most are fitted to rice-burner pieces of crap that get stolen.

The best turbo timer I've ever used was one that I built and integrated into the vehicle electronics. If you put the car into gear (gear position switch on the GU patrols) or touch the brake then the timer releases the ignition and shuts-down the engine.

I personally use my timer more in the winter, as I can safely start the truck, leaving it locked with the engine running so as to warm everything up.

After hard running or highway touring just let the vehicle idle for a couple of minutes before shutting down.
When you enter a town or city if you do run at high revs there is little need for an idle down period.
Research this sit for more detail.

Peter iv'e been a trucky for 32yrs & i always let my turbo cool down it's cheaper than a new turbo. Modern turbo's only need a minute or so to cool down.Regards Bob

Fair comment, and I agree -
But the Nissan sales staff said that the advantage of the water cooled turbo was that it didn't need any cooling off period.
But info supplied to me from Nissan Technical reckoned that you do need to cool it off after a fast run.
Is there a message there about sales staff?

Cooling down is only half the issue. Problem is if you cut the motor while the turbo is still spinning at a rate of knots oil is no longer being pumped through. Having said that it seems the only time you really need to think about allowing things to cool/settle down is, as previously mentioned, if you suddenly pull over after travelling at high speed or doing high revving work. Another point to remember is that too much idling is also not good for a deisel as it can cause glazing of cylinder walls. Like most things it is a matter of finding the balance I guess.

Happy camping.

Peter,
I've got one but as yet haven't fitted it, it as case of getting around to it. I mentioned it to the insurance they didn't seem that phased but where grateful I mentioned it. As mentioned before it's the oil that's the problem more so than the temp being taken away by the water, or so I believe. I had one on my Triton only really used it on longer runs and then no longer than 2 mins. On my GQ after a long run I leave the engine exhaust temp to get down to about 100 degrees C before I switch off, switching the engine off with the exhaust at 400 degrees C can't be good I anyones eyes which is where it gets too when working fairly hard. Our mates in Osbourne Park have ones that connect directly into the wiriing loom which make the fitment really easy. Hope this helps.Keep the shiny side up
