That was me! :-] VICS= Variable Inertia Charge System. Upper intake plenum has four butterfly valves which are vacuum operated. They open at 5500 rpm to allow more air flow into the engine. which is why we can sprint our engines out to 7k rpm. I love the sound of it myself ;-)

Well, you don´t gotta be a moron about it siragan. I said ´upper´ because not everyone knows exactly where the butterfly valves are.
