it looks like an interesting idea, although i think there are a few issues to be resolved.
1. on the valve opening graphs, there is a flattening of the curve near max lift... this would not be good for spring haronics at high rpm... as an analogy, think of clipping of an amplifiers output and it's effect on speaker cones...
2. what longevity could be expected on the components under 'real' driving conditions... that small rod (and the ball ends) seems a little flimsy for the things i would like ti to do...
lets say 9-10000rpm, with seat pressure of 80lbs and nose pressure of 240lbs. at high revs that part would have to be rather stout, especially in compression.
looks like a nice design, but i would like to see a more stout design capable of higher revs, incorporation of more of a roller type design (that stick is a bit wussy), and also not have it as a throttle, but more of a variable lift/duration.
interesting that someone from greeve would send ideas to a car club list.... nice designs tho..
if you want to make a head for a toyota K type enigne i'll be glad to try it
