  • CNC Profiled 4150 Main Bodies

    BLP offers 4150 HP main bodies with oversize venturi’s. The venturi is a profiled radius rather than a straight bore. This is achieved by machining the bodies on a CNC lathe where the radius can be programmed to start above the venturi and continue beyond the venturi to where the base plate attaches. This process allows you to achieve maximum air flow. The following part numbers are machined only and no polishing or tumbling is done. Add “M” to end of part number when ordering fully polished and colored bodies. Custom sizes available, please call for details.
