Manufacturing Capabilities

We can produce high volumes of engines at a consistent, repeatable quality that exceeds
automotive-grade standards and customer expectations.

Cutting-Edge Tools

PSI’s high-volume, precision machining center uses eight CNC machines to maximize product performance and durability. The flexible and agile block line can be repurposed to adjust to customer demand.

Quality Processes

Our quality control processes include CMM measurement and testing, and key metrics within each production area are tracked at regular intervals. All engine blocks undergo rigorous prep processes and testing to ensure their durability and prevent issues that could cause damage.

Assembly Solutions

PSI’s manufacturing processes and technologies enable us to produce high volumes of engines at a consistent, repeatable quality. Our production lines use industry-standard hot and cold testing and an electronic Kanban pull system, as well as automated foot pedals that ensure no-fault forward, zero-fault assembly.
