What is a honda vtec engine?
VTEC stands for variable valve timing and electronic lift control. What this means is that when a VTEC engine is operating at higher RPM’s, the camshaft makes an adjustemnt that allows the valves to open and close at slightly different times, permitting the engine to breathe better. What this means is increased power at the top end. VTEC usually truns on at about 4500 RPM’s. You will likely hear the engine get slightly louder and feel an increase in power. The transition is extremely smooth. It only operates when the car is being driven, not when it’s being revved while stopped. The feature is usually present on mid and high level Honda’s and on all Acura’s.
