Power through Deletion. 2015 WRX TGV Delete Kit, Part 3: First Prototypes

We’re back with another quick update on our TGV delete project for the 2015+ WRX. After designing our initial models and then 3D-printing a prototype for test fitting, we worked up a couple functional prototypes for on-car testing.

Check out a few images of our functional prototype deletes!

As you can see, we have two different prototypes. Although the shape and design are the same, these prototypes are composed of different materials. The polished unit is a CNC-machined aluminum piece. The black prototype is machined from Delrin, a thermoplastic material.

We want to explore any differences in intake temperatures provided by the alternate materials. As you can imagine, thermoplastic has very low thermal conduction properties, meaning it is less likely to heat-soak and is more resistant to heat transfer. That said, the surface area that actually comes into contact with the internal airflow is quite small. So what will be the impact on temperature in a warm engine compartment? This is what we want to find out.

Coming up – Testing

Next we need to tap these delete prototypes for temperature sensors and then start collecting data. Check back next time for a look at our testing rig, explanation of the process, and the results.

Thanks for reading!
