Custom 5-Axis CNC Machined Billet Aluminum Oil Pump Housing for Automotive Engines
Description
Custom CNC Machined Dry Sump Oil Pump Housing – For Motorsport & High-Performance Applications
Our precision-engineered dry sump oil pump housing is designed to meet the extreme demands of motorsport, high-performance racing engines, and specialized lubrication systems. Crafted from premium billet aluminum (6061-T6 or 7075-T6) using advanced 5-axis CNC machining, this component delivers uncompromising strength, lightweight performance, and exceptional fluid dynamics.
Key features include:
- High-precision central bearing bore for reliable pump shaft alignment and reduced friction
- Optimized internal flow paths to minimize turbulence and maximize oil delivery efficiency
- Multiple threaded oil ports for flexible inlet/outlet configuration
- Strategic lightweighting through precision-machined cavities, without compromising structural integrity
- Precision-machined mounting holes for secure, leak-free assembly
Ideal for use in:
- Professional motorsport engines (Formula, GT, rally)
- High-performance street and track vehicles
- Custom dry sump lubrication systems
- Aviation and industrial high-performance applications
Each housing is manufactured to tight tolerances (IT6–IT7) and undergoes rigorous quality inspection, including CMM verification and ultrasonic cleaning, to ensure consistent performance in the most demanding environments. Whether you’re building a race-winning engine or upgrading a high-performance vehicle, our CNC-machined oil pump housing is engineered to deliver the reliability and efficiency you need.
