VTEC isn't some power thingy, it's for fuel economy at lower revs. it actually retards the timing below a certain RPM. so, when it opens up at 4k rpm or whatever, it feels like it's adding power, when it's really just giving back what it took away. AND, almost every car maker has a form of this in their cars now, so it's not like we're special (from bmw's VENOS system to toyota's VVTC, etc.).
</rant>
sorry to rant, but i wish everyone would shut up about how cool VTEC is. it's nice, but not for the reasons y'all keep mentioning. and yes, i have a 3L VTEC motor in my honda, and my last car was a VTEC civic (1.7L), so I do have some idea what I'm talking about.

Second...VTEC doesn't reduce power...it saves gas mileage and increases the low end powerband (low rpm torque) by providing a low lift cam lobe...once the rpm raises and the map sensor detects the proper pressure and amount of fuel VTEC kicks in AKA...the cam lobe changes to a high-lift profile allowing more air to flow pass the valves and to the combustion chamber and provide better top end (high-rpm hp). Since the engines are small and efficient they are already great on mpg, but VTEC basically cahnges the powerband according to the factors that the ECU measures to activate VTEC. It's a take to make a small engine build more torque when it's best and more hp when it's best. Horsepower doesn't get you off the line...torque does.

First, Toyota has VVTI...yes many other manufacturers now have their forms.

Essentially I shared the same thought in my post above but not as eloquently as you put it.

is vtec then essentially synonomous with a double overhead cam?
ie. do vtecs only come with DOHC? Or can it work witha complex single cam system?

I love good engineering, I need to GRADUATE! It's simpler than it can be explained, but more complex to understand if you are unaware of the design and how the design works.
I'd advise anyone interested in understand things check out howstuffworks.com (the automotive section) and read some books free at Barnes and Nobles. You'd be surprised at what you can teach yourself to do. Take notes to understand exactly what your engine does and when it does it. Even buy a Haynes manual from Autozone and read it. You'll learn things are easier than they appear.

I like the one way system near my university, its very twisty with starights and a variety of corners. three lanes wide!
There are also some nice hillly roads that are pretty intense- so i can understand wher 6th gen is coming from

Vtec is why I fell in love with hondas. If you have a vtec take your car out when it is jsut cold enough not to kick in and floor it. then floor it once vtec will engage and you will notice a HUGE difference. And I am the one that calls my accord a stock sedan beast.
