can someone please explain to me what exactly vtech is, i tried to find out online and on howstuffworks.com but they dont have it.

what is it, exactly, and how does it work?

i cant understand how an s2000 2.0 liter engine NA puts out 246 hp, vtech must be like a little god or something with wires.

sorry if others asked this question, if theres an article or soemthing i can read, any directions to it would be appreciated. thanks all.

This should be rich, really rich.

What VTEC does is increase the air flow to the engine adding power during a certain RPM range. Do some searching on here and youll find your answer.

yeah vtec, i apologize for my idiocy. I don't actually own a honda or any vtec car, im just very intrigued by it, someone said that it increases airflow... but the s2000 is normally aspirated isnt it?

i wont be an ******* because this looks like a legitimate question

VTEC. no H.

VTEC stands for Variable Valve Timing and Lift Electronic Control.

short answer is it increases airflow by changing cam profiles (lift and duration) by using a 3rd rocker arm that gets activated by a locking pin via oil pressure.

Another note: VTEC is not the only - or the first - variable-lift type valve activation system. Ferrari uses a tapered cam lobe system where the actual camshaft moves around in the head for maximum lift and efficiency at any given RPM.

Come on guys. Some of you just don't give people a legitimate chance.

Andrey, here's so good reading material on camshafts:
