Vtech is company that makes phones and other electronics.
VTEC is the technology used in Honda's and Acura's. It's the same thing as BMW's VANOS system and Toyota's VVT-i system. What it does it monitor how the driver is inputting the gas, and will adjust how much gasoline is allowed into the engine by controlling the angle of the pistons and how much room the pistons actually give way for the gas. It does help with horsepower and mileage.

Is glass half full? half empty?
One can see VTEC as improving power. The other way to see it is it does opposite. If you have this switch that gives you more horse power when you turn it on. Then why don't they keep it on all the time? It saves gas, but rob you of extra horse power.
Other way of looking at it is in normal driving condition, the engine behaves normal. Until you push the car and keep the RPM high, then gives you extra horse power.

In hondas, it does one of two things. It can add a boost of horsepower at high RPMs (6,500-7,000), or it can detune your cam for fuel efficiency.
I don't know what that 1st guy is talking about, but it works on oil pressure. When pressure increases, the lobes on the camshaft become more aggressive, causing the valves to stay open longer. This is how you gain horsepower, not by incresing fuel. But, since more air is entering the motor, more fuel is commanded in too.

No, v-tech is some kind of custom blend of additives but they will not add power to your engine. Only a significant increase in octane will help your performance.

go read wikipedia about it
i wouldnt say hondas vtec is just like toyotas vvt-i just because honda was the inovator, toyota copied
it uses a bar to lock rocker arms together so they open longer when yuo are at high rpm... dont take it as high performance... at high rpm its 'normal' at low rpm its restricted to use less fuel.

yes it does. this is variable valve timing. it has the ability to advance and retard cam timing which can increase low end torque and also increase horse power in the higher rpms.

Here is a short video of how it workshttp://youtube.com/watch?v=AcT_ZyY3F0k.
