Teach & other auto racing fans, keen video of Mercedes turbo

I was reading about the just-finished Formula 1 season and happened across this very well animated video showing how the new Mercedes "split turbo" system works. Some pretty sharp designers there, for sure:

    I wonder what kind of engineering voodoo went on to keep that long shaft lubricated when it's spinning at turbine speed? (20-30K RPM or more) A short-coupled turbo needs several gallons of oil flow a minute to keep the shaft lubed, and it's usually less than 3 inches long.

    Hey Teach, Don't think the shaft is long enough to need lubrication in the middle just the bearings on each end. Super engineering to say no more. :applause: Later,

    Recoil is how you know primer ignition is complete.

    Yeah, pretty keen, eh? Racing (in the big leagues) shows how advancements in general automotive design will later move. Not all the goodies that were first introduced in racing make their way into our street vehicles but the list is amazingly long.

    With the emphasis on fuel management and precision engineering, automotive engineers will continue to find ways to provide considerable horsepower in more fuel efficient and smaller engines.

    I've no doubt that this new turbo design will find its way into the top line of Mercedes cars.
