Did you notice the valve spring spinning?

 

[HuskyDude]

I was just waiting for my PC to blow up...

Ya watch the valve springs how they rotate up at the higher RPM.

13000 rpm divided by 4 = 3250 opening and closing per minute.

325o divided by 60 sec. = 54.2

195,000 Opening and closing each second is that right?

You divide by 60, so that would be 52.42 times per second.
