Springless Valve System
i was on you tube and came across this......
http://www.youtube.com/watch?v=GXIdO...eature=related
this is the company's website ...... http://www.decuirenginetechnologies.com/
i did a search on TGO for this and nothing came up.....
pretty cool i think...... what does everyone else think? would this hold up on a daily driver? i bet it would be expensive tho.
opinions/comments?

Re: Springless Valve System
sounds like there is a lot of valve train noise. Otherwise I guess I would need to see some serious R&D on the system but I like the idea, and its cool they have it running with video proof

Re: Springless Valve System
in case anyone is interested more in how it works, i found this video on their website. its a video of the ohc version, but its a lot easier to see how the mechanism works. they also show the compession test. they didnt seems to have trouble pulling off 170psi....doesnt seem bad to me at least.

Re: Springless Valve System
i like the technology but i would want to see more in the way of daily drive testing in stop and go. not eveything that runs like a big dog on the track will work well on the street. i would also like to see some hp ratings and some comparisons with current tech especially valve opening and rps. a power curve would also be nice.

Re: Springless Valve System
Positive valve actuation (no springs) has been around for years in one form or another.
