V-Tec

[pimrusis]

Can't they set V-tec so it is always active? Or can you get an aftermarket product that would do it?

Do you understand what vtec is?

Variable Valve timing at above 6000 rpm or so. I think.

Read the link. It only works above a certain rpm. The engine must be working at a certain speed to benefit from the valve opening before the intake phase.

So your aware. Basically your switching the cams. A lower cam wont be optimal for a higher speed and vice versa. They are working on constantly variable systems.

The reason hondas dont have low power though is directly related to design of the engine cylinders.
