1440 rpms v8 LEGO engine via Jalopnik. The maker writes -
I upgraded the engine to a double cam setup and voila, promptly got 440rpms more. For now i’m running the engine completly unlubed. If i optimize it a bit further i think i can make it to 1600 rpms. I wonder how an inline 4 would go….. (insert manical evil scientist laughter here…)
where’s the instructions and parts list? I’d buy the kit right now!

Your vid is old.
Have you tried measuring how warm the plastic bearing surfaces are getting? Especially the crankshaft would seem to have the greatest friction forces on it, so might show the greatest temp rise. Very impressive!
that is absolutely amazing
Please please please please sell this kit!!! I would buy one in a heartbeat.
