This LEGO Flat 6 revs over 1600 RPM
This LEGO pneumatic Flat 6 engine is designed to be integrated in a LEGO Porsche 911 car in the near future. Yes, I know it is not a boxer and the crankshafts are not 120 degrees apart. However, LEGO only makes crankshaft pieces with 90 degree increments so I had to deal with it. I modified the fake engine pieces to be airtight and hold a valve core which lets air into the cylinder accordingly. Soon after building this engine, I realized that the engine blocks and 2x2 bricks come in a trans-clear color. I may rebuild this engine with clear elements so that way you can see what is happening inside the engine.
The engine runs 100% off compressed air, and no electric motors of any sort power this creation.
Minimum idle is at about 300 RPM or 20 psi, maximum RPM is 1600 at 50 psi, it probably could go faster but I was not risking going any higher pressure.
Build time: ~ 40 hours
This is a custom engine design by me, but to modify the engine blocks, I used the following guide from LEGO Technic Embodiment:
