Vvt Vs Vtec -

smooth power delivery, better fuel economy, lower emissions. Cons: It doesn't change how far the valve opens (lift) or for how long (duration); it only changes when it happens.

Modern systems often use cam phasing to fine-tune the engine's response across the entire rev range, while utilizing VTEC-style lobes to provide the massive airflow needed for peak horsepower. vvt vs vtec

Suddenly, the engine transforms. It inhales massive amounts of air, resulting in a noticeable surge of power and that iconic "VTEC just kicked in, yo" sound. smooth power delivery, better fuel economy, lower emissions
