What does all this give you? It gives you a pump with stability over 9000 RPM, proven in excess of 900whp, with higher efficiency, less friction, and backed by one of the industries best warranty’s. 

Stock oil pumps and our competitors both suffer from the stock oil pump gear design. Boundary started with a blank sheet using a design that comes straight from Boundary skunkworks. The new design eliminated the asymmetric tooth profile that puts a huge amount of stress in the root of the teeth. Then we added in a formulation of metal and heat treatment that has been race proven for nearly 2 decades. The result? A gear that doesn't break, what more can you ask for?
