turbo stuff
i was talking to one my friends and he was telling me that a 6.0 has a differient turbo than the 7.3 that the blades in the 6.0 turbo would move into differient angles i guess it called a varible type of turbo.

If that turbo gets rid of lag, i would hate to drive the 6liter otherwise... i feel for a diesel it is lacking on low end, and the wicked wheel is nothing like the turbo in the 6liter. Lacking low end is a relative term though.

That would be an EVRT... Electronic Response Variable Turbocharger... It uses an electrically controlled ring that slides (similar to the variable pitch blades on a helicopter) to change the compressor end blade pitch. The 7.3 engines that Int'l manufactured after the 6.0 was put in the 250/350 have them, but as far as I can tell, there's no way to retrofit one, as there is a computer issue (but wouldn't it be nice!)

From what I am getting from what you said, the EVRT was put on the 7.3??? This was brought up a few weeks ago and no one had heard of that. I asked it over on the 6.0 forum and no one had either. I was just curious as to where you got that from if i am reading your response right.

The computer problem being that the computer that comes in your ford is a joint effort between ford and int'l (int'l handling the engine control, ford handling the interface with vehicle systems, seat belt light, door boinger, that kinda stuff)... The PCM that international could supply you with would have to be for one of their trucks, and wouldn't have the same vehicle interface systems, the same plug, or anything else, for that matter... I'm sure someone with deep pockets and a thorough working knowledge of vehicle control systems could make it work, but for the average joe, we just get to dream... (And, as a side note, the newer 7.3's from int'l also have the split-shot injectors, and are devoid of the computer problems of the 6.0... Kinda makes you wonder sometimes, huh?)

Sounds like too much work for me, I think I'll just take one of Intl's new 7.3L with the split-shot injection and lack of computer problems and put it in my truck. Anybody know how they are comparing to the 6.0L in performance and exhaust emissions? I'll probably go to the international website and do a search on them now, just curious.

confusion on variable turbo
I think there is a little confusion here, the variable geometry does nothing with the compressor or turbine blades. It is moveable vanes before the turbine wheel that open and close to allow more or less air to move through. the more they close, the faster the exhaust moves through, which means the faster the turbine wheel spins thus higher boost pressure. CHeck out bernouli's principal and the vanes will make sense. I believe that the vanes are pneumatically controled, I think thats what I saw at the auto show.

If you remember from physics class, Air moving through a "venturi" or more restricted area moves faster, as does the pneumatically controlled vanes on the turbo, speeds up the exhuast gasses as they move through the turbo, spining it faster making more boost at lower rev's

I searched Internationals website a while ago, when I asked about the ERVT a few weeks ago and didn't find anything about it being instaled on a 7.3. they listed it as being only on the 6.0 and there big 580 cid or something like that.
So I am still wanting to know where this info is coming from, cuz I cant find it.
