After evaluating the factory intercooler, our team was prepared to begin designing an intercooler with even more efficiency. The process started as a simple 3D model that included our primary mounting points. This model was then sent to the 3D printer for some rapid prototyping.

Once our tanks were complete, we mated the different pieces using adhesive.

Shroud Fabrication
As you can see the 3D-printed tanks have numerous raised mounting points in place to hold our shroud design. On the factory setup, the base of the engine-cooling fan shroud is mounted to the intercooler, so we will need to replicate a similar setup with our design. In addition to the rear shroud, a front duct system will be incorporated to help guide airflow through the intercooler core. This ducting should provide an improvement in cooling efficiency.
The shroud was first designed in Solidworks. We then use a feature called "Flat Pack,"
