  1. here is the overhead valve video I mentioned this one gets revved to over 14k rpms https://youtu.be/nsa6kq-qqIE

  2. try crushing cylinder head valve springs racing springs have a dual and triple spring design may be harder to crush but might be worth a try! no one else has tried it I dont think.

  3. Sure thing anytime. Lots of neat stuff out there. Hope to see you make one in 4kHD would be awesome. And who knows maybe you'll catch it on video dropping a valve like yours did in your supra. Still surprising tho toyota engines are usually built for high rpms.

  4. Oh I like that sounds very promising! Now I really can't wait to see how that looks on video. And remember under high speed you will be able to see everything the spring is doing unlike those other videos I showed you which only used pulses of light to slow down the frame rate. (Old technology) I think we will get a much better understanding of what really happens to a valve spring under high rpm loads. Imagine a nascar engine and the stress those go thru. Running at over 9000rpms for 500 laps around Daytona! Not to forget they're a pushrod engine too. I'll bet if you're able to capture a valve spring in action with high speed it might just give race teams a better idea of what happens during a race and maybe help lead to better valve spring technology!

  5. And trust me valve float is no joke!

  6. Same to you you're hella cool! I will be sharing all your new videos for sure very interesting stuff and I love it! Keep up the good work! Look forward to the valvespring video soon! Thanks! : )

  7. Yes I subscribed and will be waiting for this video for sure! You may want to see some of the videos of what happens to a valve spring under high rpm loads. They will actually spin. There are many videos on youtube showing what happens to a valve spring at 6000 rpms and above. It's quite neat to see but still they will rattle under those loads and the valve locks can only handle so much. In fact an old school way we used to remove them without a spring compressor is to use a socket on top of the valve and smack it with a hammer one time and the locks will pop out and u can remove the spring and valve assembly. But yes do try the valve spring in the press and see how much pressure it will take before it fails! Should be neat to stress test a spring to its limits!

  8. Yea I just posted the link to that video I was mentioning check that out they actually narrate the video and tell u what rpm the engine is running at and it looks like slow motion but I believe they're using a strobe light on the spring to slow it down so u can actually see how it acts. Really wicked stuff that the springs can actually handle

  9. Wow I'll bet they're quite brittle from heat treating. How about a valve spring? Actually what I originally was thinking to see if the spring would break under extreme pressure or if it would spring out and go crazy.

  10. +Warped Perception nice! can't wait to see that! Absolutely loved the Heineken bottle!
