Nice fab work, does it work good? It looks like that turbo has a waste gate on it, you might make sure its either stuck shut or you need to wire it shut. That turbo is either the later ATS kit or off a factory IDI turbo.So this ATS turbo is the same as Ford's other then the waste gate.
ATF is a naturale deturgent, and a lubracator but, it will foam up in a turbo examlpe: put atf in a power steering system and drive it, you may think you have good steering, stop and turn the engine off and remove power steering resevoir cap you'll see foam or alot of little bubbles, that means your steering box is not getting enough lub and your pump is gettin too warm and not enough pressure to float the gears properly. Due to the smaller space that confines the brass barrins, if those oil lite barrings dont get the proper lub they get warm and losse form, and if you have ever changed the filter in an auto trans you will see normal clutch disk prticals in the pan and if they bypass the filter witch they due, your turbo will catch those particals and cause damage and if you put a prefilter on it that will reducue the bad but will also reduce the lub pressure.I have talk to a Transmission builder and others about this and they said the bearings are made like want is use in Auto Trans and the only thing is the added heat for the trans and I have plans to install a large Trans cooler.
The turbo shaft just ride on the oil on the brass bearings.
I could be wrong but no one has told me why; so Tell me why you think I will eat up bearings?
Very good i was hopping you would pic up on my pointRebel you have made the best argument I have hear.
As for the power steering system, it maybe bubbles because of the compression of the oil but the Turbo don’t have compression but a flow of oil over the bearings. So the ATF should not be foaming because of the turbo. It might foam because of the trans. pump but I have never heard of a foam problem in auto trans. before.
As for the partials in the oil: would these not also hurt the trans. moving parts?
:thumbsupSome good points.
Ok, I'll give you credit on where you put the turbo good spot but, i used to have a 1990 f-350 7.3 idi diesel and it was not the original motor, the owner befor me put a 7.3 idi out of a bus in to it and it had a turbo but he sold that and put it back to N/A. The engine had a turbo pedistal style manifold and the driver side, if you contact a navistar dealer they should be able to get that for you, if i can find my old pics i'll show you what i'm talking about.I'm getting a better picture of were you are coming from.
I still have a hard time understanding how the bearing will be hurt by ATF over motor oil. I'm still working on that.
I do see the problem with the higher pressure from the trans than motor oil pressure. That for sure will have to change. The 7.3 oil pressure is 30pis on the high side and the trans will be well over 100psi.
Good point :thumbsup
The one point we have not cover is the fact the piping was going to be hard after the Ford 7.3 turbo "Y" would not work on a Interntional truck. So this seen to be the best place. but with the turbo so low on the truck the oil could not be drain back to the motor so this is where the Trans came into play.
I'm going to see how they oil the Corvette rear turbo.
I still not buying the ATF vs. motor oil I'm Probably wrong but I don't see it.
Thanks keep me thinking
that will work, and your welcom and could i come over some time to check this out?:thumbsupAfter thinking about the flooding of ATF in the turbo I was going to have to do something. So I'm changing this over to Motor oil and I have bought High performance pump for the Corvette rear turbo.
I'll never know how it will work off of the Trans. but I'm being safe and not taking a chance of breaking down.
Thanks for the input:thumbsup
