Cam at 14k rpm

[Bonnewagon]

Unbelievable. Watch as this cutaway valvetrain operates at 14k and the valves cycle 118 times per second. Your eyes can't keep up.

Pretty neat!!

Notice the valves rotating.

If the cams are turning at half the speed of the engine that means the engine is turning at 28,000 RPMs
Unless overhead cam four stroke is different
