    DIY: Shaving RBC intake manifold

    I'm not done yet but a member sent me his RBC and asked if I could shave it for him. Of course I was up for that challenge :thumbsup:

    Here is what I started with



    my weapons of choice, cut off wheel, grinder, sander, 80 grit disc

    started with small things like these


    then cut down


    then sanded smooth


    then also did a bunch of misc ones


    smooth



    the big one I'm working on though is eliminated the sensor ports. Started worth:


    started cutting


    kept cutting


    smoothed it with sand paper to see how it's coming



    I'm waiting to weld up the holes but here is my so far end result




    I really enjoyed this manifold so if anyone else wants one shaved let me know :thumbsup:

    Nice, looks awesome! Will you cut out the 'bridges' between the 1-2 and 3-4 runners? Or leave those in? And what color will it end up being?

    Ok so more updates on the RBC

    I put my throttle body on to compare the edges


    Marked it with a marker


    and cut it down



    First I hit as much as I could with an 80grit disc wheel





    Then to test to see how it would work I did a small section in flap wheels



    It was looking good
    Then I used flap wheels 60, 80, 120



    obviously I am far from done but taking a break for now.

    Wait, one of the ports you removed is a vital vacuum source from the IM. Now what?

    So went out to the garage for an hour and kept shaving on this manifold...

    decided I didn't want this here


    so I cut it off


    and smoothed it out



    also cut out this area so we can put the vacuum hose barbs



    and sanded down the welds (need to redo two of them though... )

    Decide if you are going to cut out the webbing or not?
