From conception to perfection: A spotlight on the engineering and manufacturing facility at Integrated Engineering


At the heart of a true engineering firm lies some of the most unique machinery and processes you can feast your eyes on. From 3D scanning and printing to CNC manufacturing and stress testing, we are taking you behind the scenes of our engineering and manufacturing facility at Integrated Engineering.

Starting with a simple idea, our development team lays out a plan of attack for each product that we develop. Feedback from every member of our team is taken into consideration before the engineering process begins. We look into the feasibility of manufacturing, which includes looking closely into material selection and required processes. Estimated sales volume, part cost, expected retail cost, and distribution are plotted out beforehand, providing us with an idea of the amount of resources that should be allocated to each project, as well as helping determine batch sizing.


Our team of highly qualified engineers begin the designing and engineering process with use of advanced CAD software and other high-tech development tools, such as 3D scanners, thermal imaging cameras, and custom-built test apparatus'. Once the part has been designed, we can 3D print prototypes, which are used for test-fitment and, in some cases, actual use on a running engine. We take note of fitment and design, then reevaluate the solid models in the CAD software, making any modifications needed.

If the part needs testing done on an actual engine, it gets outfitted for use on our in-house engine and chassis dynos and put to the test. This is extremely important for intake manifold development, as it allows different runner lengths, diameters, and plenum volumes to be real-world tested. The data gathered from dyno testing, along with the Computational Fluid Dynamics (CFD) flow simulation software, allow us to manufacture the best performing intake manifolds in the world.

Once the design process is finalized, parts go into production. Billet machined parts are sent back to our in-house machine shop, which features an arsenal of CNC machining equipment. Whether it be a simple turned fitting or a complex surface-milled part, our machine shop is fully capable of pumping out all of the parts that we offer. Connecting rods are also finished in house on our top-of-the-line Sunnen connecting rod hone and rifle drilled with our EDM, setup specifically for the long, narrow holes required for connecting rods.

For products that require configuration and assembly after machining, we use our custom-made fixtures designed for each task, making for repeatable results. Even a task as simple as clocking a compressor housing on a turbo is done with a fixture.


Parts like our high pressure fuel pumps require break-in before packaging, which are performed on a custom-built dyno that runs the pump in the same conditions it will see installed on a car. This test rig is outfitted with pressure, speed, and flow sensors so that we can keep a close eye on each and every pump that we run.


Machined parts receive a multi-point inspection to confirm all critical tolerances. They also go through a tedious visual inspection process to make sure that no parts leave our facility with flaws. For parts such as intercoolers, we use our custom pressure testing station to pressurize them before shipping. This is to confirm that no welds leak and there are no pores in the cast end tanks.

We take as much pride in our packaging as we do with the rest of the process. By utilizing custom foam, boxes, and poly bags, we securely package each component for our shelf, then each order into its shipping box.

  • Wow,
    Just read the "Conception to Perfection".
    Very impressed, and humbled that my home-made stuff is pretty small change. But I appreciate the details of what I can hope to someday achieve.
