3d profile cams like Ferrari...with a greater range of duration change, Ferrari could implement late intake valve closure. Or we could use a system like the "Williams Helical Camshaft" which is basically like the Ferrari cam except instead of the whole shaft moving one piece stays fixed and the "helical" part moves around it to vary timing. The problem with non variable lift in the second example is poorer low end performance, but something tells me a system like D4S would help. I don't know which one is easier to implement, variable finger follower pivot => early intake closure or this, seems like the first. The improvement would not be that much greater than say Valvematic or Valvetronic or VVEL, but combined with one of those systems it could be highly effective, though probably too complicated. Discuss?
Not gonna see that tech debut in a $20k sports car. Valvematic maybe, and it's about damned time they put it in something worth a damn and send it over to this side of the world.
