This in my theory would mean that both intake and ehaust recieve the exact same added lift/duration. Even the diagram from howstuff works theoretically suports my theory. Is there any facts about how vtec can only engauge on the exhaust (i heard intake sometimes too) side.


I dunno, but im still thinking about this one...
