    I have a set of stock forged pistons from MAHLE The skirts are HUGE. They look more like diesel pistons Cant I mill most of this skirt off flat with the bores? Also that cubic point above the pin bore? Then some crown work? I am looking to get 100 more grams off of the up and down moving parts in total. This paired with the work I have mentioned on other threads about removing a rib on the conrods should get me there. The goal as mentioned in other threads is to reduce stress on the rod big ends.... The pulling forces during open valve. For anyone who is reading my stuff for the first time This engine suffers from mass and oil issues that I am working to correct. The smart choice here would be to run better pistons but money..

    So risky without knowing where the exact thermal expansion rates are on each area.
    Stress riser points.

    I have only seen blueprints of old TRW Powerforged pistons.

    Autotech makes the lowest cost custom pistons.
    Need the right forging blank.

    It was done empiracal testing by TRW.
    Ran them in past.
    Super strong.
    A little heavy.

    You can cut away al the skirts with a Hacksaw.
    Run it and Blow it up.
