Wat is VTEC???

SOrry everyone.....im not much into the HOnda/Acura scene so forgive me pleez. I was wondering wat exactly is HOnda's VTEC and wat is HOnda's i-VTEC???

Look here (http://www.automotiveforums.com/vbulletin/search.php?)

And while you're at it, look here too (http://www.m-w.com/netdict.htm)

just make it easier for him and tell him.

It is good tho to try and search ur topic before posting tho esp something like this one where everyone asks the same question all the time. Since im not that much of an @ss like most ppl try this link. http://www.howstuffworks.com/question229.htm

or how bout you just go here: http://www.automotiveforums.com/vbulletin/showthread.php?t=77265 af's own vtec thread...btw, i used the search feature to find this, it is a useful tool...

Thanks and im sorry i'm not a HOnda fan.

vtec = bwaaaaBWAAAAAH

rahhhhhhhhhhhhhhhhhhh unwahhhhhhhhhhhhhhh aahhhhhhhhhhhhhhhhhmmmmmm blaaaaaaaaaaaaaaaaa

vtec = bwaaaaBWAAAAAH
LOL

vtec = hhooonnnnn....DDDAAAAAAAAAAAAAAAA!!!!...bring ding ding..ding ding...

ok i get it...HOnda damn!!!

Vtec just lets the engine breathe in the higher rpms sustaining its torque through the whole power band.

v tec is a valve trane system that swiches between a low duration cam wich decreases valve overlap so you can make low end power not contaminate the intake charge and idle And a high duration cam that increases valve overlap, and screams at high rpm {scavanger afect}

your all wrong...

im gonna finally set it straight, FINALLY!

vtec is not any of said stuff above. its really magic!

im not kidding. pure magic run by the same leperchaun who is behind that lucky charms cereal! hes running a global pyramid scheme with honda and general mills. no joke

why in the hell do you type honda HOnda everytime?

My bad bro. Honda....better.

YEs oops, yes

No, it doesn't switch between cams, it switches between cam lobes.

In a nut shell a lower duration cam lobe runs for economy under XXXX rpm, when it hits XXXX rpm, the vtec solenoid opens and fills a passage way with oil, which locks the rockers and engages the secondary cam lobe, which is of higher duration, and not economical, but makes more power. That is the magic of vtec (or any variable valve timing system) it (they) allow for normal operation and economical fuel consumption, while maintaining a sporty top end.

If it switched between cams we'd have quadrouple overhead cams. :icon16:

i didnt say cam shafts i said cam. a cam SHAFT has lots of cams on it. ie cam lobes 1 DOHC vtec cam SHAFT has 12 little cams on it thats why its called a cam shaft. out of thoes 12 little cams 4 of them are high duration.

Technically yes, but for practical purposes when saying a cam 99.99999999999% of people are refering to the camshaft as a whole, as in " I bought a CTR intake cam", that doesn't infer that I bought one cam lobe, now doesn't it.

i agree 99.99999% of the people do refer to a cam shaft as a cam
but beleve me i am awair that b series engines are DOHC engines QOHC
i have a dissasembled vtec heas at my shop rite now

True. When people say cam, they mean cam shaft.
