5000 rpm Working Lego Fake Engine

Original design idea by: Lego Technic Embodiment

Today I decided to finally make a video of my working Lego fake engine.
It is built in a 4 cylinder boxer setup and uses modified valves, pistons and cylinders. It does run without a flywheel aswell, but then it runs quite rough at low rpm's, so that's why I'm using a flywheel in the video.

It is capable to rev over 5000 revolutions per minute at 6 bars. Although I have to say I did not measure this engine yet so this number is based on speculation.
BUT!
This is not my first Lego engine, and you can watch a video of Nicjasno, who did a inline 4 engine doing a similar amount of revs and actually measured it. As you can hear the sound of my engine is very similar in frequency, if not higher, so I'm very confident it is at least able to do 5000 rpm's.
If you like this video, maybe I'll do another video measuring it...

I know this is not the type of content I usually do, but I just felt like sharing since I have had this engine for about a year now and modified it very recently... So... Yeah... :)
