Having run hundreds of tests on the. effect of 2-valve throttle body upgrades on everything from stock to supercharged combinations. (both centrifugal and positive displacement), it is safe to say that throttle body upgrades on the 2-. valve motors are a worthwhile endeavor.
VDC may refer to: In technology: Virtual design and construction, modeling software and techniques to design and evaluate possible construction processes; Volts of direct current; Video display controller, a computer graphics chip; Vehicle Dynamics Control, a means of increasing vehicle stability through a combination of throttle restriction and braking
A virtual circuit (VC) is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data. The term virtual circuit is synonymous with virtual connection and virtual channel.atalink layer and network layer virtual circuit protocols are based on connection oriented packet switching, meaning that data is always delivered along the same network path, i.e., through the same nodes.
