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…)
