Whoaoo!! What a load of Awesome info. Learn something new everyday. Resonant frequency of the springs? Never thought that was an issue. Now I know. Good luck this year Rod and the rest of the team.

Yes indeed. The mass of the spring itself can cause it to lift out of the pocket or drop off the retainer when pushed to the limits of valve acceleration/decelleration at high rpm. Geometry and wire diameter matter alongside spring rate. Conical valve springs are bringing new limits to valve control previously unachievable.

Physics! Newton, Hooke... This makes it crystal clear why it is so important to understand the difference between a symptom and the underlying problem. The discussion around valve springs is a perfect example of this.

Don’t forget about that 60psi of boost and that explosion of the combustion engine going on. All have effects on the Valvetrain thru pressure and harmonics

I know that Steve Morris, running smaller engines for similar purpose (drag and drive), says that he always runs a very gentle cam profile and that most people run too much lift for it. Asymmetric profiles too. He can make however much power he wants by adding boost, but making it last requires the right cam. I wonder what his profiles are like compared to yours.

- Great! Thanks, very interesting! ".. resonant frequency", this is what I've been telling folks. Spring resonance has got to be immensely important for power I thought some years ago after lifter bearings went. Pressure lowered 150lbs; - Wow!

Wow what an informative video. It's amazing what you learn with this technology. But when you see it explained it clicks. So if you did a regular compression test on a engine just say you get 200 lbs average. At 8000 rpm depending on cam of course you might be getting 100 lbs of compression. So valve float is basically the engine not building up enough compression to fire fully or at all. I know you don't have the rotating assy in but it would be interesting to see a compression test through the rpm range to see the same results. Poor man's spintron??

Very informative video, thank you. Can you tell me what the engine is? I seem to recall it being a 5.300, and heads look to be semi hemi, what are bore/stroke?
