Frequently Asked Questions

Every assembly starts with a complete de-burr inside the pump. Each housing is stoned to remove high spots on the sealing faces, then thoroughly cleaned. Every component is checked for form, fit, and function. From there we create a quality record listing all critical clearances in the assembly and package a copy of that blueprint with the product. Once function is guaranteed, we lubricate every component inside the assembly to minimize priming time and wear. Finally, we apply any required sealants, Teflon, or thread locker and torque all fasteners to specification.

Black Series gears feature a patented Vane Ported design that helps the engine survive beyond 7,000 RPM by increasing the maximum oil flow the pump can produce at high RPM. They are also treated with MartenWear, which prevents the gears from breaking down or wearing. MartenWear was flow-tested on our bench to 12,000 RPM without any wear, ensuring full pressure even at F1 levels of abuse.

The CM-OPG-MUSTANG fits almost every Mustang from 2011–2021. The only exceptions are the GT500 Mustang from 2008–2014 and the GT500s beginning in 2020. F150 fitment is a little more complicated due to changes in the gears over the years:

• 2015–2017 F150 trucks use the same gearset as the Mustang (CM-OPG-MUSTANG).
• 2011–2014 F150 trucks used a special gear set (CM-OPG-F150).
• 2018+ F150 trucks also use the special gear set (CM-OPG-F150).

Be careful with the F150 gear set: it will physically fit into Mustang housings but will not produce any flow or pressure.

The BP-S1 contains a non-VVT gear set inside the housing. This assembly works well if you are running standard engine clearances and planning to stay under 8,000 RPM. The BP-S1 comes standard with 0 shims, which the customer can specify at no extra cost. The BP-S2 contains a unique high-flowing gear set and is the better option when the engine has larger bearing clearances and needs additional pressure to cope with large bearing loads. The BP-S2 comes standard with two shims, which the customer can also specify at no extra cost.

The number of shims you need depends on how much RPM and horsepower the bearings must sustain. The engine survives more abuse with more oil pressure, but drag on the motor increases as pressure and flow go up. Your engine builder’s plan should include a recommendation for the pressure the engine needs to survive at the intended level of performance. As a starting point, use the chart below:

• 0 Shims = 60 PSI / 200 WHP or below.
• 1 Shim = 66 PSI / 250 WHP or below.
• 2 Shims = 72 PSI / 300 WHP or below.
• 3 Shims = 78 PSI / 350 WHP or below.
• 4 Shims = 84 PSI / 500 WHP or below with large clearances.
• 5 Shims = 90 PSI / 600 WHP or below with large clearances.
