Toyota came out with VVTi-L (Variable Valve Timing Intake Lift) which kicks in at 6,000RPM.

Nissan brought out Neo-VVL (Variable Valve Lift) which kicks in at 5,000RPM.
So can u actually feel an increase in power surge as they say 'kick in'? I've seen some clips on youtube with VTEC supposedly kicking in... the only thing i noticed in acceleration was an increase of sound from 5500rpm, other than that, it just accelerated smoothly to its redline.
