Ever since its addition into our product range, the fully externally adjustable billet RB oil pump has been a significant success. There are a range of features that our billet oil pump has separating us from our competitors, as we use years and years of knowledge acquired through our cast pumps and directly apply that to our billet one.
The housing itself is machined from aerospace grade billet 7075 series alloy, as opposed to the less effective and cheaper 6000 series billet alloys used elsewhere. We conducted much research in order to conclude that the 7075 was the superior option. In actual fact, our testing revealed that the expansion rates from the cast housing to a prototype 6000 series housing were virtually identical, and the expansion of the 7075 was virtually zero.
Revised oil galleries inside the housing with tighter clearances allow the pump to be run with greater oil pressure, furthering the capabilities of the externally adjustable valve. The pump also features the option to utilise an external pickup with a -10AN feed into the housing to maximise the oil flow through the pump. The internal and external pickup can be used simultaneously, or you can choose to run the internal or external feeds by themselves.
As with our cast housing pumps, the 7075 billet backing plate still features.
*The oil pump also requires our exclusive Sine Drive collar
