    Why isn't triple scroll a thing?

    If twin scroll works better for 4 bangers and 6s, would a theoretical triple scroll 6-3-1 manifold pairing 1to6, 2to5 3to4, triple scroll turbo have any benefits? lol I know triple scroll doesn't exist but perhaps it would be beneficial.

    Why isn't it a thing?
    I think mostly because the cylinder count of most turbo cars isn't divisible by 3.
    ie. it would work for 3/6/12cyl engines, vs 4/6/8/10/12 for the twin scroll.

    Sounds cool, but it sounds very niche market. I imagine there are other reasons as well

        No demand, no need. There are quad variants out there but the cost for the smaller hp gain is not worth it from a retail stand point.
