This custom 363 XR piston is used in the NMCA Extreme Street Class. It has produced over 1600 Horse Power and withstands the test of time. We have used this applica- tion to develop our piston skirt profiles along with our Patented X Groove Skirt fea- ture. With the X Groove fea- ture we have been able to reduce oil ring tension while maintaining the critical oil control required in a boosted application. The X Groove also greatly increases piston skirt, piston ring and cylinder wall life. Proof of Concept!
