That is pretty cool. I don't know the number.

A while back, I met this guy from greece that had this theory how to make B series VTEC heads into I-VTEC. Although at first it sounded like a joke I read his stuff and was impressed.

Take some time to read these links

Let me know what you think.


Basically the cam profile seems to be controlled by a movable wall that dictates where a roller will be able to move, which is all controlled by the throttle itself, actuating a roller to alter the lift and overlap of the cam.It allows you to have only one cam lobe that hits a roller, which in turn hits the rocker arms. The position of the roller, however, determines how much the the cam lobes gross lift and duration would actually be seen as valve movement. In essence, infinantly variable VTEC.
