Using proprietary Speed Flow™ technology, Dart has developed more efficient port designs with improved velocity and flow capabilities. The combustion chambers and ports have been redesigned for greater breathing characteristics and more controllable combustion. Casting walls are cleaner and more consistent, resulting in better control over flow and heat.
