Better check out the vacuum theory and suck on the exhaust too!)

I've heard about the turbo spin with the exhaust pipe but it doesn't really hold do to the valves in the engine and think about the fact you maybe have a 75 mile per hour wind at the exhaust tip.
I've seen people who told me the truck ride ruined their turbo but the turbo looked like it was whipped from use long before the truck ride! Seals were leaking before and bearings were way to weak for a twenty mile ride to have been the cause.
The chance that I was going to load something onto a truck that was going from NY to California I'd probably tape it! The chance of someone starting it up without removing the tape and causing excess stress on the turbo from not having a outlet for the exhaust and bending the fin's and stressing the bearings do to the added heat, while just another thing to blame a part failure on that might not mean to much either!

That's what I call the 'true-true-and unrelated phenomenon. In other words it is true that the tractor was just hauled somewhere AND it is true that the turbo is now malfunctioning BUT the two are unrelated and you can tell this by seeing a used up, worn out or abused turbo that was destined for failure long before the trailer trip.
This is a common logical fallacy that people fall into. Two events seem to be related but no proof of the relation is or can be established.
I often use this (extreme) example: 92% of people diagnosed with lung cancer ate carrots at least once in the year prior to their diagnosis. Some people would read such a statement and assume that carrots cause lung cancer. There is nothing silly about the statement, just the conclusion.

pretty good discussion here.....my intent in posting it was to relate what my service manager said he experienced with 3 machines at his dealership in Texas. Just some advice to err on the side of caution....what's interesting is that even for a simple subject within a free exchange of ideas, there are those who seem to get an attitude and have an agenda.....would be great to discuss then move on good luck! bb

Well, you have to admit, when you really think about it it just doesn't compute. And when you hear advice that sounds good but doesn't make sense, it makes you wonder and think about it even more. And I don't think that just because someone might disagree with me that they have an attitude or an agenda. Just think of this discussion as a collective 'thinking out loud'.
Several people have cited good reliable sources telling them that this is a potential problem. But several people have pretty well explained how the physical reality doesn't jibe with that advice. I've been in the sciences long enough to know that things don't always make sense at first. Maybe those of us that doubt the advice are missing something. Who knows.
One of the things you look at when you examine any given medical intervention is what is the potential harm. Even if an intervention can prevent something deadly, if the intervention could possibly kill you then its not a good intervention especially if its preventive potential is if-y.
In this case, covering the exhaust can provide other benefits like keeping trash and moisture out. And there is virtually no risk associated with it (unless you really plugged it). So, despite all the agendas and attitudes, the advice is still good even if it doesn't really have the specific desired effect.

The only reason I can see to cover it is to prevent dust or dirt or water from being fired up into the exhaust and into the turbo. The weight of the particles could get them quite a ways into the exhaust, think of a sandblaster pointed into the exhaust tip. This would extremely on those engines with unmuffled turbos with straight pipes.
HOWEVER:
It will not pinwheel unless you have a major manifold leak, there will be some air movement but at low velocity and probably not in the same direction enough to turn the turbo. All the air entering has to leave the same way it came in.

OK, I'm the one with "attitude".
What some person of unknown credibility said happened somewhere....
ongoing mumble mumble, but no take apart details - - so the sky WILL fall and we had all best duck and run for cover.
If it doesn't make sense from a mechanical, physical, engineering point of view then it doesn't make sense.
As N80 said; You might be able to show correlation, but that doesn't prove causation.
Someone put up a NEW urban myth - PLEASE ?!

This is an easy myth debunk or prove... put a tractor in a wind tunnel. Case closed.

OMG!!! I had carrots twice this weekend!! Thanks for the bad news George!!
BTW I close up my exhaust and I don't even have a turbo!! I don't want my engine pinwheeling!!
AND I even have an enclosed trailer!! So there!
