    F1 Mercedes split turbo

    Hoover, why didn't you think of this?

    hmmmm.....
    longer center section to house the shaft.
    if the cartridge housing is thin enough, lubrication can still be center......

    less heat on the compressor housing........

    all good...

    What kind of shaft are they using to minimize the torsion losses? Titanium? What bearings do they use in this setup?

    Oh, and obviously, I want one of these!

    The heat exchange is actually negligible. Main benefits come from lack of intake piping, which leads to less lag and better weight distribution. Less lag saves "spool up the turbo" KERS energy to power up the engine. Less piping also allows for better packaging so the side pods are smaller. More air is used for down force less for draging the side pods. Trans is also moved forward, thus better weight distribution. In addition to better car balance from centralized weight, tires heat more evenly all around so they can recover more KERS energy yet again. So splitting turbine and compressor created a number of benefits translating into speed around the circuit. This design is also not as easily duplicated as double diffuser couple years back. Cannot simply drill engine block though to install the long shaft. Need to design engine around this feature.
