VTEC, My friend told me what it does but...

...I want to get a more exact answer. What exactly does the VTEC do and is it really THAT much better than non-VTEC?

[JDMFantasy2k]

vtec stands for - Variable valve Timing and Electronic lift Control, Basically, on the camshaft (or shafts in dohc vtec) there is an extra cam lobe. On low rpms the the lobe is disengaged, however when the engine reaches a certain rpm, the extra lobe is engaged and changes the timing of the valves to produce power more efficiently at high rpm's. There's also different types of vtec ( sohc vtec, dohc vtec, i-vtec, e-vtec and i think there's others) it's all basically the same idea but for different purposes (dohc vtec=high performance, e-vtec=engine economy etc) i think that's basically it.

on our cars I beleive it kicks in just after 4500 rpm, have you ever driven a noinvtec accord?
it feels considerably different, you don't get the same pick up after that rpm range on nonvtec

<---NonVTEC Accord :D I have always told myself "Its better for boosting this way" but will probably never have the money :D
