I've got the 2.4l manual and I like the fact that it has low end grunt as well as punch from 4500 RPM on. All this with A-1 MPG, couldn't ask for more........except the V-6 six speed in the sedan!

<rant> 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. -s

I test drove a caddy cts last week, a freind of mine, brand new, from the showroom 255 horse power, not sure of the other details, first thing i noticed was the pick up was a lot slower than the vtec, even with what steev was saying about power benn taking awaw before the 4000 rpm level. Now i dont know the official times of thes cars but i know 0 to 60 i could get there faster than this new caddy and that gas some extra horses on engine. just and observation, personally i love the vtec from the first time i drove it. have to aks again though, will supercharege increas my top end speed or just get me their quicker, no problem wiht the latter of course accordlowered 04, so what is in that thing?

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.

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?

VTEC actually only operates the intake valves...I'd say most of us with a USDM F-series or J-series engines has a SOHC...and most have VTEC also. So you don't need DOHC to have VTEC. The cam lobes you can think of as the rocker arms locking together to raise the lift. With DOHC it will lift the intake camshaft only. With SOHC cam the system is designed so that (yes their is only one camshaft that operates the intake and exhaust valves, but can use variable valve timing on the intake side. 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.
