Prototype Fabrication

After experimenting with some boxed designs in Part 1 of this write-up, it was time to turn our attention to a shrouded setup, similar to what we offer for the 2008–2014 models. We’re hoping we could utilize the piping from our existing kit, which is well designed and has proven power gains. After placing the shroud into position, we found that it would certainly fit, but would require some modification. The fabrication work began! Check out a few shots taken during the process.

Once all fab work was completed, we had a functional shroud that we could use for testing purposes. We could also use this shroud to develop a 3D model for our production units. Take a look!

We could then combine this shroud with our intake pipe, shown below, to capture some performance data.

This pipe features a stock MAF housing, as well as an air straightener to provide laminar flow across the sensor.

Check back next time for a look at the testing process, and the results from our dyno pulls! Check out the teaser shot of this car getting setup on the dyno!
