Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

  • Steel pistons are coming

    Found this article on Mahle making steel diesel pistons for passenger cars - apparently will be in someones production cars in 2014. Smaller lighter pistons will result in smaller engine blocks or to start with lower friction losses with longer conrods.

    I think it's meant to be behind a paywall, but you can see the first two pages in the preview.
    System Comparison of Aluminium and Steel Pistons for PC Diesel Engines - Springer

    There is less information on the Mahle web site.

    Amazing that significant engineering progress continues even with such basic parts as pistons.
