BMW S1000RR Technical Video - Valves in Motion High RPM (14,200 RPMS)

Thats ridiculous. I thought it hit the redline at least 3 times before it did! I find it very interesting how the spin changes based on RPM.

i couldnt help but squint because i thought something was gonna fly off and come outta the screen LMAO....

I was also waiting for something to fly off and break the camera lol.

Watching this makes me wonder how the cams don't wear down. Clearly oil lubrication, but I mean this is just such basic technology its surprising it has lasted so long and works so well. I would think the move to EM valves would have happened already...though there are plenty of problems w/ EM valve tech. as well besides the cost.

I can't believe how fast they open and close! It's surprising there's any time for air to pass through.

This is why intake/head design has such a large impact. Air flow!

agreed, there is a time well before it maxes out that you stop being able to see what is going on lol

here is the same vid, different perspective:

enjoy

Super crazy. The air must not even feel quasi equilibrium at speeds like that.

I now understand how things like VICS and VRIS make an impact.

I'd love to see how fast the piston would be travelling.
