im gonna back up darron on this one.
just dont go WOT to 100mph, skid to a stop and turn the truck off.

A little more explanation on what they said... Some turbos are cooled only by the oil passing through them. If you just shut the truck off while it's hot, the oil sits in the hot turbo and cokes. A turbo timer idles the engine for a while to keep the oil circulating until the turbo has cooled down. Our turbos are water-cooled, so the oil doesn't absorb as much heat, so coking isn't really a problem.
Adding a turbo timer will only help, but it isn't as necessary on our trucks as on some other turbo vehicles. My Sy has about 134k (60k in the last two years) and the stock turbo is still in great shape. Honestly I drive it like I would any other vehicle, I just shut if off when I get where I'm going. If I've been hard on it right before stopping, I will let it idle for a bit first, but that's about it. I just leave it running while I gather up my things or whatever, instead of shutting it off then getting my stuff.

I use my HKS timer only in the summer, and thats for a minute only

I hear people say "oil-cooled" a lot. I believe oil is there more for lubrication purposes than cooling ones.

djs,
I have alot of experience on whether the Turbo Oil cokes on the GN, which has no H2O cooling. I have always used synthetic oil, and never had any coking problems on my GN turbos (3 by now). I always heard that U had to change out the turbo oil supply line. I have observed them, blown thru them a couple of times, and have never seen any pluggage. But then conventional oil has a T rating about 100 Deg lower than synthetic, so all bets R off on conventional oil.
I will have a PTE-63 - a GN style Turbo w/o cooling, on my rebuild and I don't plan on any Turbo timing. Altho' I may put some kind of a Prelubing device on, and if I go w a pump system, I will probably get the turbo Postlube option.

whats a turbo postlube?.....exactly what it sounds like?

Mr. M.,
the Preluber has a control module where U can program the amount of time that the supplied Oil Pump stays on at startup. With the PostOil added option, U can also have the pump come on for a specified time period after U turn off the engine. The pump went bad on my system after only about 5 K miles, and when I called them about it, of course it wasn't covered.
So, for $550., I didn't get a whole lot - just another failed experiment. I've had more of those than I'd like to remember - enuf to make a sane person quit. This system used to be carried by Summit, but I don't see it any more - maybe that's a clue.
I do like the idea of prelubing, and may consider one of these systems from ACCUsump for $180. Not sure we need postoiling w synthetic oil, unless someone can show me evidence to the contrary.

yeah, that sounds like a really good idea. post lube would be nice for the cooling effects, although i highly doubt cokeing is a massive problem on our trucks but its just one more step to take to save the life of the part. wouldnt there be a way to make the pre lube also work as a post lube?

a question - and probably a dumb one - but bear with me...
now, our turbochargers are oil and water cooled. is the water a proponent of the stock air/water intercooler, or is it routed from a separate source? if the water IS from the stock intercooler, would a timer be vital on a truck upgraded to an air/air intercooling system, or how would that work? just curious.

The turbo coolant lines go to the block. They're a part of the engine cooling system, not the intercooler system.

Mike,
Not a dumb idea at all ! To do Turbo oil cooling U will need a pump to turn on & off. I guess w the right hardware and controls, one could switch the water source for the Turbo from the radiator to the air/water IC system. Then U could turn it on & off as needed to give cooling after shutdown.
It would take a whole system design, and I don't know if it would be as good as keeping the Oil running thru the Turbo.
