Also know as contact reduction grooves, these grooves limit the   piston\/cylinder contact during high temperature and RPM.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eAccumulator Groove\u003c\/em\u003e\u003c\/strong\u003e is a V shaped groove machined in the 2nd ring land to collect excess   blow-by between the top and second ring. This groove collects residual   gasses during combustion and alleviates top ring flutter while   increasing ring seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eCP groove\u003c\/em\u003e\u003c\/strong\u003e stands for Constant Pressure Groove. This groove works as a channel on   the lower part of the top land that equalizes pressure to the back of   the top ring groove.\u003cbr\u003eWhen used in combination with lateral gas ports, the CP groove helps   keep gas ports clear of carbon build up. In addition, the CP groove   prevents the top land from smudging into the top ring if the land rubs the cylinder bore.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eDouble Pin Oilers\u003c\/em\u003e\u003c\/strong\u003e in conjunction with our dual fed reservoir add twice the amount of oil from the cylinder wall to the wrist pin.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eX-Forgings\u003c\/em\u003e\u003c\/strong\u003e are designed to minimize friction and reduce weight without   compromising strength. With the use of bracing and ribs, the forging is   configured by adjusting the weight balance between high and low stress   areas. This design enables the use of a shorter pin for added strength   and weight savings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eRadius Domes\u003c\/em\u003e\u003c\/strong\u003e are used to maximize quench while eliminating possible hot spots that promote detonation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eCam and Barrel:\u003c\/em\u003e\u003c\/strong\u003e Extensive research and development has been done to find the optimum   skirt shape for each piston.
