What does a valve spring look like when it's operating at 8500 rpm?
Thanks to the magic of slow motion, we can see that valve springs move around quite a bit.

That is SUPER cool to watch

Way more jiggly slinky action than I expected, and that's a dual-spring setup!

The algorithm suggested this one to me a few days ago too.

All hail The Algorithm.

Exactly why I felt the need to share, definitely a lot more movement than I would expect from a valve spring.

Looks like we both have good taste in YouTube videos.

Lotus has a piece of software that calculates the motion of all the individual coils of a valve spring, since that's pretty critical to determining valve float.

Wow! So much jiggle and so much rotating!

As the bishop said to the actress

Can someone please explain why it's rotating so much? I'm genuinely curious and can't really figure it out. I assume vibration but then why wouldn't it just find the 'heavy' end of the spring and stay there?
