The RB26N1-OPG throws away the weak asymmetrical rotor design and replaces it with Boundary’s own race-inspired symmetrical gear pattern. It is designed to be tighter sealing and created to be a higher volume so it will have a slight uptick in idle pressure and mid-range pressure up to the relief valve limit. It also has the designed crankshaft interface which reduces wear on the crank surfaces and eliminates the need for a crank spline drives. This is a huge benefit as you can simply put the gears in the housing and run them as a stock replacement.
