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.
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 PrototypesWe 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 ››
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 PreparationFor 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 ››
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.
