    If there isnt a rough build tutorial atleast, im going to cry

    I'd make that crank 180 degrees. That way you'll have a smoother running engine, the primary forces will be balanced. A vast majority of production engines will have 180 degree cranks with their firing order being 1,3,4,2

    Im not into lego at all but this thoroughly impressed me. You sir have gained a new subscriber😎
  • Heyy, you can make some intake manifold with pressure chamber, plus runners for each cylinder. I believe it will add some more response and effiicency

    Wait so is the vacuum blowing? If so itd be cool to see a supercharged version of this somehow if its possible to run it off the crank or something

    So its basically a pushrod 4 cyl Sickkk
  • How do you connect the slide valves to the crank? Brick-to-brick connections aren't strong enough for me.

    wouldn't it be smoother with a flatplane crank tho?

    How competitive is this scene? I used to do R&D for Shark vacuums and I have many thoughts and feelings.
