We have been hard at work developing our 2013 Ford Focus ST intake system. When the stock intake system was removed, there was room to get creative for improving airflow. Right off the bat, you can see how Ford designed its intake to grab as much cold air as possible by using the two tubes that both conjoin at the front grille and connect into different points on the box. We know it will be important to retain this feature and include it in our airbox design for the Focus ST intake.

Fabricating the Prototype

With the removal of the stock Focus ST intake leaving a good amount of space, we wanted to design an airbox that uses that space effectively. After the space was carefully and thoroughly surveyed, we got to work fabricating and welding together a working prototype!

In our last post we took a look at the stock Fiesta ST downpipe as well as our slotted flange design based on the stock flange. We are still planning to create both a catted downpipe and a non-catted downpipe for race applications, so let's take a look at the progress!

Downpipe Design

After fitting the flange to the turbo, we began to piece together the rest of the downpipe coming off the flange and meeting with the exhaust. Both our designs feature a slotted flange that bolts to the turbo, in addition to a flex pipe near where they meet with the exhaust. This is important because the entire exhaust system will move a bit, and we need a flex point to allow for this. Not allowing room for flex in the downpipe would most certainly harm your exhaust system and possibly the turbo itself.
We began by laying out the components of our prototype next to the stock Fiesta ST downpipe for comparison. Check out some shots below!

Introduction and the Stock Downpipe

Another addition to the Fiesta ST collection! Our Fiesta build is coming along nicely, and I am happy to announce some progress on our downpipe project. As with any R&D undertaking the first step is to take a look at the stock setup and see how it can be improved.

Stock Fiesta ST downpipe

Although Ford has a pretty nice design, we are planning to make it a bit better by increasing the diameter of the downpipe to 3" throughout. As opposed to the stock unit which features 3" pipe only where the downpipe meets the turbo. In order to achieve excellent fitment with the turbo, we will keep the flange as similar to stock as possible. To collect the most accurate measurements

As many of you are aware, here at Mishimoto we have been going Fiesta crazy developing various Fiesta ST parts such as;

• Performance Aluminum Radiator
• Oil Cooler Kit
• Performance Air Intake
• Direct-Fit Baffled Oil catch can
• Downpipe and  Intercooler/Piping coming soon!

Up next is something that the team here has been very eager to start development on, the Fiesta ST Cat-Back Exhaust! We are excited to let you in on the details of the development of our first prototype. As with any exhaust project, we are shooting for improvement in flow over stock as well as a great overall tone that is drone-free. Check out the details and let us know how we did!

Stock Component

To begin, we gave the Fiesta ST's stock exhaust setup an once-over to see what we were working with. While it is not terrible, we do see some room for improvements. As you may have noticed, the stock exhaust has two mufflers. One rather

With testing and data collection complete, we assembled our final prototype BMW F30 air intake to confirm that the full kit fits flawlessly prior to starting production. We have been pretty excited to see this unique kit come together. Check it out in its final form!

Final Intake Images

Our final prototype BMW F30 intake was cut from a sheet of metal using a waterjet. Once we had the template cut to our drawing and model specs, we bent each piece appropriately.

First, the base of our airbox.

So far this Fiesta ST has had an interesting life with Mishimoto. The very same day that we drove it off the lot, it was rolled into our development facility and fitted for its first modification: a prototype baffled catch can kit. Why did we chose to begin with this? From our experience with other EcoBoost equipped vehicles, we know how prone these engines are to blow-by and carbon buildup. If you want to read more in depth about the benefits of a catch can, check out our complete write up on Blow-By 101. Installing a catch can right away allows us to protect the engine of our new development vehicle and gives us more time for data collection as we work on developing additional Fiesta ST parts. Last, but certainly not least of all, we asked for your feedback and received an overwhelming response to create a Fiesta ST catch can (yes we do listen to you!).

We already knew our BMW F30 intake system looked fantastic within the engine bay of the F30. With our final prototype design fully complete, it was time to see if our intake system would produce any improvements in both intake sound and power output.

Dyno Runs

We strapped our test vehicle to the Dynojet and began making pulls. This particular vehicle was equipped with a aftermarket tuning device, and we would be checking data both with and without this software as a means to compare the stock intake system to our prototype design.

Time for an update on our F30 intake project! Check out the continued progression of our development below!

Airbox Base Fabrication

We left off last time with the completion of our intake pipe fabrication that leads to the airbox. Next on the list: assembling our airbox and refining the design to the appropriate shape we wanted to achieve.

We started with the base of the box, which will be utilizing the factory air duct to acquire a cool stream of airflow.

After wrapping up some loose ends with our E36 and E46 projects, it was time to turn our attention to one of the new offerings from BMW. The  4-cylinder turbo N20/N26 caught our eye as a very interesting new engine, and we decided to bring one into the shop for an initial look at the vehicle and to begin developing a few products for this chassis.

Stock Intake System

Before pulling out the welder and aluminum, we needed to evaluate the stock intake system to determine our

After selecting a catch can location and fabricating a mounting bracket, we needed to fully install the can/bracket combo and begin putting together a set of CCV lines to complete our kit.

Catch Can Lid

Before doing so, the functional prototype of our catch can lid arrived for evaluation by our team. Check it out!
