How flexible are the P80, 90, and 93 engines at altitude? The turbo will of course help to mitigate power loss, but the engine will still become overfueled and hot the higher the elevation, right?

It seems like having to go through all the trouble of removing the engine shroud to reach the fuel screw every time you ascend the Himalayas and then descend back to sea level would be absolutely ridiculous.

Now could you kindly please give your opinion on my question posted here? http://real4x4forums.com/PinzgauerBBS/v ... =8&t=10013

Sorry, I really can't answer that question.
I'm no expert on diesels persay (my 718 is the first diesel vehicle I've ever owned) and secondly as we don't have any mountains high enough to affect engine power in Australia, it's not something I've ever really researched.
I'd suggest you join Robi's German/European Forum and ask the question there, as they have high mountains/alps and more TD's
.......I'm sure someone will be able to help.

Diesels do not have a fixed mixture like a gas engine. The engine takes in a full quantity of air on every cycle and add diesel according to the throttle position. Less throttle, less fuel, less bang, lower rpm. More throttle, more fuel, more bang, more rpms. Too much fuel for the amount of air, it smokes. It's that simple. The turbo does help increase the amount of air, as you stated. With turbo boost the effect of altitude will be less pronounced so it may be worth revving a little higher (within reason). If you are short of air the motor will be less powerful and require a lower gear.

So don't worry. Anywhere you take the diesel, from below sea level to the mountains it will work without adjustment.
