This weekend I achieved a new world record, just shy of 15,000 RPM with a Lego engine, no doubt it got up there at one point but my tachometer is too slow. Thankfully it didnt blow up but that’s because I only let it go for a few seconds. There was no friction damaged surprisingly so i didnt bother adding that into the vid but let me know if i should do a durability test.

Check support @LucasDynamics and see his world record run with no glue.
I’ve been working on this for a long time so y’all better not say I copied him😅
