When does VTEC kick in?

it's like an afterburner...it only kicks in when you want to go supersonic 
why does it matter? the SOHC VTEC is just for fuel economy and the extra 20 horses or so they managed to squeeze out of that engine. you really can't even notice when it changes over, it just makes a lot of noise.
It's nowhere above 4,300 RPMs... it is 4,300 RPMs. Dyno results have already proven this. Not to mention you can hear it get louder at that point.
The other #s are coming from previous generation Civics.
It doesn't really matter.
ive heard that on the 7th gens its like 2500 - 3000 but search casue i know its on here
The EP3's VTEC is at 2,200 RPMs.
On an EX - from experience and the dyno results posted by another member on 7thGenCivic.com, it's 4,300 RPMs.
VTEC lights have reported #s that somewhat rival where the EP3's VTEC kicks in.
my 5th gens around 4000-4500 area
Even more so is 2,200 RPMs but the D17 is not a D16.
I would think 5,800 RPMs is a bit high for a D16 IMO... I don't see how VTEC would engage with only around 1,000 RPMs left in the powerband. I'm convinced it's the intake manifold doing that as the same thing occurs in the GS-R but I have no proof towards the D16.
Spend a lil' money and put your car on the dyno to see for yourself. See where the engine begins to make more power on a D17 and it's gonna show 4,300RPMs. Or just push the throttle cruising at 3,000 - 4,000 - and 5,000 RPMs in any gear below 4th gear. The car is gonna drag at 3k RPMs - a lil bit after 4k the engine will be louder and it will pull - and at 5,000 RPMs it's not gonna pull as hard... no torque.
This is an ongoing argument... I've read anywhere from 4300-5800. But, if you go here... http://www.turbod16.com/
There's a thread about it and a guy actually has a dyno. But, on the dyno an argument can be made for the 4300 and the 5500 theory? So to answer you who knows, we need some hard facts sheets from honda.
