>From what I was taught about the VTEC System... The cams sit on hydrolic lifters and when the engine hits 5200 RPM (the magic number) the lifts rise/drop (I dont recall as I've had a few drinks at the club tonight) and thats when the engine gets that extra boost. Some say the boost feels like a turbo. It simulates a performance cam at 5200 RPM.
