I know is has something to do with a thin layer of oil that is constantly pumped around the shaft. Can someone please expand on this a bit more.

No thats okay man, i dont need to know that bad, Thanks though!
Don't worry, Bruno is just trying to find out what it is so he doesnt make hisself look like a dumbass *runs for his life* J/K, hes probably sleeping, but tomorrow he'll be on while hes SUPPOSED to be doing his real job :P Which is of course moderating TCC.

Thanks again red90DX!

Naw, I did see it last night.... but quite frankly I'm not a big fan of doing other ppl's homework. I've done enough of my own homework in my time. I figured I'd leave it for someone else or Jacob just do his own damn research - lord knows there is enough info out there.

Thanks to all who trust I know what it is.... and ye who trust NOT shall search

Ok, whatever....

there are several key components of a turbo...

compressor, bearing, turbine, and control (wastegate usually).

A turbocharger compressor has a compressor wheel, diffuser, and housing. Air is drawn in by the compressor, accelerated rotationally, yada, yada, yade, finally it hits the diffuser which slows down the air so that both pressure and temperature rise. The diffuser is formed from the backplate and part of the housing. The backplate is just part of how a compressor of this type works - it forms the diffuser to slow down and compress the air.

In other words it's got nothing to do with the fluid bearing for the shaft

you can skip the intricate details of a turbo, it'll just put most ppl to sleep, and that doesn't make for a good project. Use a clip out of F2F2 in order to raise interest 1/2 through the presentation or whatever you gotta do.
