Re: Variable valve timing...how does this work? 900 1995

posted by  someone claiming to be Arno Griffioen on  Thu Dec 14 01:33 CST 2000 [RELATED]

VTEC actually brings a completely new cam profile on line (usually much more agressive for power up to 9000 rpm in the power-oriented VTEC types) once it gets activated. It is not a valve-timing system in this regard.

The VTEC cam has a second cam grind on it, but these can be actuated by rocker arms which have a hydraulic 'lock' on it to enable the use of this alternative cam profile.

Bye, Arno.
