Flex-Free Cornering. Fiesta ST Trunk Brace R&D, Part 4: Testing Data

The testing of our Fiesta ST rear strut brace involved three different driving conditions. Cornering: 30–40 mph, slalom Braking: 50–0 mph, stop with ABS engaged Acceleration: 0–60 mph, full-throttle run Each setup (with and without brace) was tested on the same day on an identical surface and with the same driver. The tests are repeatable and will provide an accurate comparison of rigidity in the rear body portion of our Fiesta.

Flex-Free Cornering. Fiesta ST Trunk Brace R&D, Part 3: Functional Prototype and Test Rig

In our last update, we left you with some mock-up prototype pieces that we used to create and refine our Fiesta ST rear strut brace design. Since then, we’ve worked up a couple of functional prototypes to test our ideas for stiffening the rear of this hot hatch.

Initial Prototypes

We constructed two prototypes of this trunk brace. The first prototype is finished in a black powder coat, and we’ll use this unit to evaluate for aesthetics and fitment. The unfinished (“raw”) prototype is going to be used for testing purposes, meaning it will be modified. First, check out our powder-coated unit bolted … Continue Reading ››

Power through Deletion. 2015 WRX TGV Delete Kit, Part 4: Product Testing

We’ve got some interesting plans to evaluate the performance benefits of our TGV delete kit. In addition, we want to evaluate any appreciable differences in terms of air temperature between the two materials (aluminum and Delrin) we have selected for our prototypes.

Test Preparation

For our first assessment, we will evaluate airflow temperatures in both materials during dyno testing. The goal here is to determine whether the different heat transfer properties of the two materials have an impact on the airflow within the TGV unit. Ideally we would use pre-TGV and post-TGV sensors to evaluate this, but for our initial test a … Continue Reading ››

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.

Power Through Deletion. 2015 WRX TGV Delete Kit, Part 2: 3D-Printed Prototype Test Fit

3D-Printed Prototypes

To confirm the dimensions and design of our prototype, we decided to utilize some of our rapid prototyping tools. We fired up our 3D printer and loaded the model. Check out a couple images showing the progress of the print.
