The Boundary Billet back plates use advanced CFD simulation and exacting 3D precision milling to create a blend of engineering and manufacturing that produces less leak by, less aeration, less cavitation, and more high RPM flow.
Plate is cut from billet steel, 5 times as rigid as aluminum, reducing blow by and air ingestion
Plates features MartenWear surfaces for long life
Increased volume and reduced foam increases engine bearing life
Utilizes surface grinding to create the ultimate pump seal
Includes high pressure o-ring seal to eliminate leaks
