		<description><![CDATA[Tweet From a technical point of view, throttle response can be measured by has your engine can build vacuum in its intake manifold i.e. via throttle pressure. The faster and higher peak vacuum is reached in the intake manifold, the higher the pressure differential will be between outside air, and your engine. This pressure differencial forces the air to flow from the area of high pressure (outside air) to the area of low pressure (the engine and cylinders), and the higher the pressure difference, the greater the pressure force, and the faster the air flow into the engine. This is essencially how throttle response works. To improve throttle response several engine alterations can be used to achieve a higher peak vacuum in the engine or a faster change in vacuum per throttle input&#8230; some of these include: 1- Using undersized intake pipes and intake plenum runners to increase the airflow velocity in the intake system, making the engine able to suck all the air out of it faster and create vacuum sooner. 2- Adjusting intake cam timing to open the intake valve as peak vacuum is created inside the cylinder near bottom dead center. 3- Reducing the overall intake system [...]
