This Slow Motion Footage of a Valve Spring in Action is Mesmerizing!

Posted by: Jesse Kleib on 11/17/2021

Naturally, as an engine runs we don’t really get to take a look inside of it but I’m sure that a good portion of us have seen what it looks like when valve springs are firing away, compressing at hundreds of times per minute, so fast that you can barely see what’s happening.

This time, however, we get the chance to see a valve spring in a very different environment as someone has taken the liberty of filming such action but then also adds another plot twist into the mix in which they slow it all down so that we can see the spring vibrating frame by frame.

It might sound like a pretty simple undertaking but when you watch it down in the video below, it actually ends up being quite mesmerizing. Without a slowed down video like this, it’s really hard to visualize all of the motion and vibration that these springs go through on a regular basis.

Valve Spring Dynamics Movie – The Enterprise Edition of Engine Analyzer Pro lets you enter details about the valve spring(s) you are using. It will actually import files from the Spring Wiz discussed in Item 1. It will then run the spring(s) in the Engine Analyzer Pro's valve train dynamics model and see what the springs are doing, if they are going into resonance, allowing the valve train to go out of control, etc. The Enterprise Pro's calculations are much more detailed than the simple Spring Wiz. And it does not say if a particular combination is good or bad. It just shows you what is happening and then you must decide if you want to use it.Please follow this link for further information about the Engine Analyzer v.3.9 Pro in The Enterprise Edition; long time customer of ours sent us a high speed movie of a valve spring pack in operation at high RPM. Here you can see the coils oscillating and the outer spring actually breaks during the movie. It really gives you an appreciation that things are not always under control, even in the most well built race engines. Please watch movie showing actual valve spring dynamics (and spring actually breaks)You need the Enterprise Edition to be able to simulate valve spring dynamics, which is a $250 add on to the Engine Analyzer Pro v3.9 B. Many customers likely own the Engine Analyzer Pro v3.9 A. If so, the 3.9 B update is $95 (with many new features, engines, etc) and the Enterprise is another $250, for $345. However, we do a package update/upgrade for $300, a $45 discount.To email us about updating or upgrading or call 248-473-9230.
