It has been a while since we took a look at what is going on in the world of the Fiesta expansion tank. In our last post we test fitted our 3D-printed prototype on the Fiesta ST. After fitment was confirmed, we played the waiting game for our final prototype's arrival at our development facility. Our best efforts at being patient paid off when we had two packages arrive this morning!

We left off development with a neat look at our first prototype, when we determined the shape and path of our brace and printed out mounting brackets for each side of the piece. By using specific angles with our square material, we were able to avoid modification of the seat mounting bracket, retain rigidity, and provide a bar that is easily hidden by the rear tray.

Our last image showed our fabricator tacking together the material. Below is what we ended up with.

We then installed the floor panel mounting covers.

It's been a while since our last update on the Fiesta ST cat-back exhaust and we are excited to let you in on the details of the final prototype! The last detail to square away was the exhaust tips. While the tips we had were decent, we found them a little on the plain side so we switched it up. Rather than the single-wall tips, we went with a dual-walled setup that we think look much better on the ST and will hold up better over time. Check out some photos below!

Now that we have a solid direction for our design plans, this project is moving right along. Last time we started the fabrication process for our fan shroud design. This unique setup would utilize the stock fan motor and blade, but we would relocate it in a space that would allow our thicker Ford Fiesta radiator to fit properly.

Fabrication Continued

With our shroud completed to its basic shape, our final portion of the design required mounting the fan to the shroud, creating a fan-blade cage, and creating appropriate mounts for the stock fan controller.

We started with the cage, as this piece would determine the location and design of the other components on the list.

It's been a few months since our last major update, and for good reason. Our team has been quite busy. As a quick recap, last time we test fitted our first Ford Fiesta ST (FIST) radiator prototype, only to find that the core thickness was larger than the vehicle would allow. Once the radiator was bolted to the fan shroud, the shroud made contact with numerous components on the engine, prompting us to pull out our markers and take a second look at the drawing board.

Now, keep in mind the FIST has some serious cooling issues. Any pleasures on the track are normally negated after a lap or two causes coolant temperatures to reach the stratosphere, prompting a quick dart to the paddock. To improve the chances

Chassis rigidity is extremely important for on-track handling, response, and feel. Ford provides a well-designed chassis with the Fiesta; however, as you can imagine, there is always room for improvement. Within the short time that this car has been available, the aftermarket has provided some great options, including better dampers, stiffer springs, and thicker sway bars, to enhance handling.

Our company will not likely dip into struts or springs, but we are certainly interested in helping stiffen the chassis. Our Mustang EcoBoost front strut tower brace is underway, and we recently launched development of a Fiesta ST rear strut brace. Time to get started!

What's The Plan?

Our goal here is to link one side of the rear trunk area to the other. You may wonder why this is needed. Doesn't the floor/body connect the two sides? Yes, but keep in mind, the floor is not made from a thick material. During aggressive cornering, the floor will see some pretty

After installing the Fiesta ST induction hose, it was time for the moment of truth! The Fiesta is once again up against the dyno to see what this induction hose brings to the table.

Initially we were expecting this hose to help with flow through the intake, but we were certainly surprised by the results. Our little Fiesta saw gains of 5whp and 10wtq with this induction

We received our final silicone prototype for testing and got straight to installing it on our Fiesta ST. This install is a breeze! After removing two quick clamps and a barb fitting, the stock hose was out and the Mishimoto hose was installed and looking good. Take a look at our black hose option installed on the Fiesta ST.

You may have seen our R&D post on the full Fiesta ST intake, but this one is a little different. We are developing a silicone induction hose as solution for drivers of mainly stock Fiestas who don't want to replace their entire intake system. The stock rubber hose can be restrictive due to its shape and size. We believe that by creating a more free-flowing alternative we could see some substantial benefits without heavy modification to the Fiesta.

First we examined the features of the stock hose. Aside from a barb fitting, the hose has a fairly straightforward design. The stock hose has quite a few ridges and flex sections throughout, not to mention a small inner
