this has to be the biggest lego vacuum engine in the world,
it has 4 huge 6by6 pistons each with a 8 stud stroke .

can you make a tutorial on the first one please.
it seems like vacuum engines run better than pressure engines, at least steam engines. is it because the ratio of atmospheric pressure to low pressure is greater than a steam engines pressure ratio?
Great job, is the blue or red faster I can't tell
the blue on sounds like a diesel
I think your gonna need a stronger vaccum lol
