That's pretty phuckin cool. Only question I have is if it's so great, why haven't more people tried it? According to that video, valve spring companies should be out of business by now.

around since the 60s.

Sounds like a good ass idea to me. Not only more power, but not having to replace springs every season !

No prices though, hurry up and patent that thing dude!

Im with maliboost, didnt look like there was much oil coming out of those rockers...but kinda makes sense b/c with the springs gone you wont need as much oil there to cool them down...just enough to keep the rockers moving.

I talked to the guy responsible for that system at PRI. He is a ball buster. He had some other cool ideas like the internal supercharger. They are looking for people to invest in the deal. I think it could work.

F1 uses pneumatic valves; The only way you can achieve 20,000 rpm for extended periods of time. I think I have also seen systems that use electro-magnetic-actuated valves. Ducati has used the Desmodromic system for along time.

F1 uses conventional cam followers to open the valves, and pneumatic springs to close them. They do this because at extremely high rpm there is so much energy stored in conventional metal springs that the valves literally "bounce" off the seats when they slam shut. Electromagnetic valve actuation and pneumatic poppets were basically banned from the sport before a feasible system was ever fully developed.

This system is much more like the Ducati Desmo system, as was noted earlier in the thread. Until I see them buzzing it to 9500 on the dyno, I'll stick with springs.
