We are back with more on our Fiesta ST downpipe project. We know you are long overdue for an update, so we’ll dive right in. After fabrication, we read that some other aftermarket downpipes for the Fiesta ST weren’t as successful at making power as downpipes typically are on other applications. We still wanted to test our downpipe designs to see the data for ourselves, and decide if the downpipe was worth manufacturing for the Fiesta ST. After testing was completed, the data confirmed our suspicions that the Fiesta ST is pretty darn efficient on its own, and the addition of … Continue Reading ››
It has been quite a while since our last update, and we are glad to be wrapping up this project! One of the reasons for this delay is that, based on your feedback, we have decided to add a few more options for this exhaust system. You might remember from a previous post, that our engineers enjoyed the louder sound of our non-resonated exhaust after having listened to both the resonated and non-resonated versions. Since there were no improvements in horsepower with either option, we based our decision to create the exhaust on sound only. To refresh your memory, here are some … Continue Reading ››
We are narrowing down our selection of core designs through both extensive research and some pretty neat testing processes. After seeing some impressive heat transfer numbers on our first round of Ford Fiesta ST intercooler testing, we decided to focus on producing a better balance between pressure drop and reduction of intake temperatures. New prototypes were constructed, and we were ready to make some dyno runs. Continue Reading ››
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.

With our final prototype in hand, our team went to work bolting everything into place. We’ve made minor tweaks to the design, so we just want to be sure fitment is spot-on for our final iteration. Check out a few shots from the final install. Everything bolted on perfectly, and this setup … Continue Reading ››
