turbo bearings

Roller Bearing: More $$$, better response, most are water-cooled.
Journal Bearing (AKA plain bearing): Less $$$, can be oil-cooled, more lag.
I've run both kinds, and to be honest, it's not a biggy. Seems IMO, the roller bearing will take more abuse, but others say the opposite. I've kill a few plain bearing chargers, but no roller bearing chargers yet.

I have some 125,000 rpm bearings that I'm going to try out on a few proto chargers.. but it takes some precision machining to get the cartridge ready to convert them over.
IMO the biggest advantage with ball bearings is that they don't need a thrust bearing. The thrust is usually the first point of failure on a journal bearing type charger. Once you overcome the film of oil on the thrust bearing surface, you get metal to metal contact and it's all over.

I think you are right. Journal bearings have been in chargers for a long time right? Ball bearings more recently? Its kinda like in 1970 if I told sombody I was going to machine steel at 30,000 rpms and 100ipm they would laugh me out of the shop. It seems the same would apply here.
I could see that being a true statement since they run on an oil film, but you have the thrust bearing to worry about at high rpm also. So I'd say that the thrust bearing problems at speed outweigh the advantage.. but I'm no expert.
Correct me if I'm wrong but in the past BB turbos couldnt be rebuilt and the center sec was a throw away unit? I do have an Inovative turbo that I was told could be rebuilt if needed. Still new in the box tho.
what is a Inovative turbo? im not looking to re build a stocker, just trick one out. i have a small machine shop and can make anything.
They make turbos...like precision, garret, holeset exc. From what I have been told your need a very expencive balencer to work with turbos
balancer? I might have that covered. I'm just trying to be different there must be guys out there messing with stock turbos
there must be guys out there messing with stock turbos
I was not mocking your spelling. i was curies about what type of balancer they are talking about. if it was not for spell check i would sound like a idiot.
