    TBM Grate vs R&D Grate

    Has anyone installed the TBM Intake Grate on there FZ? I am not happy with (as many others have testified) the R&D Grate I have installed now. Just wanting to know how it fits, does it stick down in front of the rideplate like the R&D one does? I had my plate modified by Jim but now have this ramp created by the R&D Grate hanging down right in front of it. That doesn't make sense to me.

    the grate is supposed to hang down, it forms a step which actually improves performance.

    I have my TBM grate sitting here waiting to go on the ski. I can tell you the build quality is way better than that of the R&D SVHO grate I had. The R&D grate did perform well so its a solid design performance wise but build quality definitely was lacking. The TBM on the other hand looks like a finished product with a quality casting job, light years ahead of the R&D cast.

    Nice, let me know how the fit is and post some pics of it installed. Be nice to get some comparison test of each grate.

    The grate is supposed to hang down a little lower than the plate. A few people tried making them flush, and it didn't work out well.

    Correct! it will actually slow the ski down.... I have to admit it... I was one person that tried making it flush only to realize a speed loss

    I'm guessing that little lip right before the plate creates a litte air pocket (creating some lift) and less friction which means more speed...?

    Yep, it's acting like a stepped hull and reducing drag.

    When you're going 70+ I can see where that really comes into play...
