RE: THIS is how VTEC works!!
Driving around at higher RPM's is going to cause wear on any motor, no matter what technology it has. Why would you even want to drive around at 4500+? I mean, running up through the gears getting on the highway is one thing, but just coasting at 5krpm is, well, silly.

RE: THIS is how VTEC works!!
yes, i know that...... I wasnt talking about coasting at high RPM's, my question wasmoreso directed to when to shift. Is it significantly worse to shift at around 4-4500 Rpms than it would be to shift around say3-3500?
I mean this is probably a dumb question, but seriously I dont know anything about V-Tec (other than what I just learned from watching that video). And I was led to believe that these engines are designed to operate at higher RPM's if need be. Take it easy on me, Im new to Honda!! haha

I know this video is long, but incredibly interesting. It includes a section about the i-vtec system. I may be wrong but for some engines like this is the variable valve timing only just retarding the intake values closer? That's what it makes it seem with this engine.

If you don't care about anything else, the i-vtec explanation is around the 2 minute mark
