At www.pattakon.com a new Continuously Variable Valve Actuation system is presented, with working prototype photos, plots and animations (even stereoscopic ones).
Any engine, racing or normal, can be improved as the torque can be about constant from very low revs to the top allowable revs of the engine.

Comments? Objections?

Thats a very interesting project, never seen an engine controlled by valve lift as opposed to throttle before.
