holden_fan2005 Posted February 22, 2010 Share Posted February 22, 2010 That video is seriously amazing. It still baffles me how such things work at such a high speed/turnover rate inside of an engine Quote Link to comment Share on other sites More sharing options...
evil_datto Posted February 22, 2010 Share Posted February 22, 2010 Correct me if I'm wrong, at 14,000rpm each valve is opening & closing like 116 times per second, right? Quote Link to comment Share on other sites More sharing options...
hoov100 Posted February 22, 2010 Share Posted February 22, 2010 And just to think, most modern bikes can sit at 14k RPM for a couple hours strait, before they would die. Its hard to believe just how much engines/cars have changed in the past 20 years. They are so close, yet miles apart when broken down.

Tony D Posted February 22, 2010 Share Posted February 22, 2010 I like the rotator function being shown. The stripes on the spring rotate nice at speed... Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted February 22, 2010 Share Posted February 22, 2010 Think about all the resonance frequencies encountered from idle to 14,000rpms that have to be dealt with! Also amazing that there is no valve float, I assume. How much higher can desmodromic heads go? Quote Link to comment Share on other sites More sharing options...
olie05 Posted February 22, 2010 Share Posted February 22, 2010 I'd like to see that in ultra slow motion. Quote Link to comment Share on other sites More sharing options...
letitsnow Posted February 22, 2010 Author Share Posted February 22, 2010 (edited) If you look, the coils on the valvespring aren't all evenly spaced, wonder why that is? They don't move much, maybe it is an attempt to remove 'unsprung' weight. I'd like to see that in ultra slow motion. I was hoping at the end it would do that, but they didn't. There was another high speed/slow motion valvetrain video from something else, I'll see if I can find it.
