Copied from Italian Ducati engine, nothing new.

@TheHiryder When you say nothing new, I am wondering where you might point to another example of a desmodromic valve train system being used in an American V-8 engine?

The desmodromic system is new to me and very intriguing stuff! Have you tried your system on comestic OHC engines? Also how do you achieve proper valve-seating without valve-springs?

[EmpEntTV]

@eddiesautoworks, check out this other link on You Tube, Look up EmpEntTV and you will see our other video that is related to an OHC system.

We have done this for OHC engines as well. Valve seating is achieved through a cam system that both pushes the valve open and then pulls it shut.

that valve train requires a lot of maintenance. more problematic. cup cars run around 10,000 rpm with teal springs. pneumatic valves would do better than steal and these decuir things

@swoopp How would you know that? how many hours have you spent on the dyno proving your point?

you cant reinvent the wheel , this is not new technology ... change the title of this video to >>>> "desmodromic valve train system" . come on now , are we supposed to thank Decuir Engine Technologies for this system ? NOT ! this ain't news to me . patents for this design were applied for in the 1800's

just saying ...

[EmpEntTV]

@lolahavasuaz I believe you have missed the point, what makes this new is that it is a desmodromic system for an American V-8 configuration engine. Can you point to any other valve train system of a desmo nature for such a style of engine? Its quite humorous how comments from people with no invention of their own are able to make fairly uneducated comments about this system....just saying

Ignore all the naysayers. Have a few questions comments though. I used to have a rev kit (additional springs that seat at the bottom lip of cylinder head valley overhang and seat on top of the lifter) on a sig erson billet roller cam 778 lift in addition to triple valve springs in a chevy small block. I could see how this would save/conserve horsepower. Do you have a way to measure how much horse power is consumed by having to push open the valve springs?

How much horsepower is saved using

@ifixipods LOL, hope you like the expense that comes with floating valves as well.

[ifixipods]

...but I like floating my valves :(
