E-Series VansTechnical discussion of topics related to vans powered by any of the Navistar engines. This covers a broad number of years, but there isn't enough demand to split it any further.
What has the experience been with a non turbo 7.3 at high altitudes, say above 8 or 10 thousand feet? Or even above four thousand feet for that matter.
Am going to (thinking? ) about converting to a camper and considering installing a turbo for high elevations. Keep the boost about one psi. Have not read anything about a turbo causing cavitation. IMHO, since cavitation is caused by expansion and then contraction of the cylinder wall, adding additional fuel will put more force into the explosion causing additional expansion and contraction. Anyhow, cavitation is something I do now want, even if it is free.
Think the cost/performance/benefits might be worth the install in the Rockies and Cascades Mountains?
Lets hear!! Good, bad, indifference.
This is also being posted on the 7.3 non PSD web site. All imputs appreciated.

All OEM except for air conditioner. Oh, some maintenance items have been replaced.
How many miles on this rig? If you have over 80 or so, forget it. Just my opinion. Yes, in the mountains a turbo is the thing to have.
Do turbo's cut the IDI's life? Some say yes, some say no. The real reason the turbo is a good buy is the performance you receive for your$$. If you have more then 80k, or you just don't want to lay out 3k plus$$ for a turbo, contact Stan's Headers. No, you won't get the high altitude performance you would with a turbo, but from the Emails I have received, Stan's products are a big improvement in power for the $$. You'll get other opinions I promise!
Me? My van is stock other then a three inch bank's exhaust. I'm bucks down and can't afford a turbo, nor do I have the $$ for headers.
I am mainly looking for high elevation performance in the Rockies. When I convert to the camper, will not be in a hurry to go from point A to point B. May drive slow so can sight see and other people can blow their horn at me.
Mileage on van is around 63K. Have tried not to lug engine.
Van is completly stock. Except have taken out the bench seats for the van pool.

My PSD has incredible power in the mountains. I could hardly tell the difference between 1000 and 10,000 feet. I would say it is definately worth it. You must have been mistaken when you said you wanted to keep the boost around one psi. How about 10 psi, that would do the trick. I believe the new PSD's run 15 to 20 psi.
