I just got my 2.0 heads back from Len (Hoffmann automotive) and they are beautiful. It'll be weeks before I am ready for them but photos will be forthcoming.
In the meantime, I muse about valves...since fuel injectors can be precisely controlled in timing and range of movement, with stronger electronics of course, could not intake and exhaust valves be moved electrically thereby allowing variable timing and maybe even reach. Yes modern cars have variable cams but wouldn't electrical valves be infinitely varible? Surely engineers have considered this. Enlighten me if any of you know. Thanks. |

QUOTE(Ductech @ Nov 10 2012, 01:32 AM)  Oh make it desmodromic whilst your at it ! You could reverse polarization to reverse the direction at anytime. No spring return necessary. It would be by definition desmodromic in function as there would be no return spring in the configuration. |
