It depends on if they are sold as components or as a assembly. Garret claims to VSR balance their stuff which means they balance it as a assembly. I wouldn't mix and match those parts without rebalancing it. I have had brand new Garrett's checked for balance and had them be out by quite a bit. BW's stuff is component balanced only.
Huh? LMM Turbo Shaft Question.....

a teaspoon of oil goes a long way, like blood. I will keep my corrosion protected aluminum surfaces, thankyou! The pcv reroute, IMO, is the swiss cheese airbox of the new millenium.
Larry, my reference is about overreaction. Blood, oil,...
each seem to emote the same silliness. The idea that a PCV reroute is beneficial in any way is fiction.

what about removing hot air, part of the pcv re-route is removing hot air from the turbo, also gives you the ability to somewhat improve the air flow by plugging the hole flush that the hose used to dump in.
Here's my thinking: The center shaft is machined, and very small diameter. Whatever inbalance there could be in the shaft on the compressor side, it would have a really small effect as long as the shaft is true. Bent shaft, all bets are off.
I'd be surprised if swapping compressor wheels would affect the balance if the shaft runs true.
Pretty easy to test your theory. Run it on a dyno with it disconnected and connected.
I tend to agree, whatever effect PCV gases have should be small, but I haven't watched the outflow at 500+ rwhp.
Who's going to test?
Adam, are you pulling my chain?
show me a peace of alluminum that has "corroded/rusted" away without any friction...
freious metals will do that... allum will do it IF there is rubbing or some taking the oxidation off the surface to get a shiny spot on allum.
show me a peice of all that has "flaked" from corrision
and we are not talking about current flowing throught each one
:hello:
Postive Crankcase Ventilation is srticly an emission device that was implemented by the EPA in the late 60s... porpuse to route combustion blow-by gass back in the combustion chamber and out the exhuast system. to reduce emission
The shaft might be balanced but it doesn't mean the turbine wheel is. Out of balance from end to end can also destroy turbo's just like the components being out of balance. It may not destroy a turbo if run in a mild application but it can when a turbo is pushed to it's limits. This is part of the reason when a shop balances a turbo they do it as a assembly.
The oil vapor can and does form a paste going into the motor. Mix it with small amounts of dust and dirty that get by the air filter and you can have an abrasive paste. If you doubt this pull the cast intake off of a LLY-LMM (my LMM had 500 miles and the paste was already there) and dig a finger full of it out. Then rub it between your fingers. It's not something I'd want to go through my motor over a long period of time. Reason enough to reroute it .
.
the intake exposed to exhaust gas recirculation?
EGR soot. No soot, no goo. It sure as heck doesn't come through an element with a 99.3% efficiency for particle filtration.
By the mess that is left down stream of my vent tube, I'm gonna say that the there is quite a bit of chit blowing out!
