This is a pretty cool post, something a bit out of the ordinary for our projects. We typically utilize our existing silicone boots in our intercooler kits, intake systems, etc. For this project, we decided to manufacture the first portion of our intake system from a wire-reinforced silicone hose. This would facilitate an easier installation, and it would also provide a smooth airflow transition from the small turbocharger compressor inlet to our intake's large pipe diameter. Since we like to show you what goes into developing our prototypes, check out the process for creating our silicone turbo inlet hose below!

Printing Our Fixture

The hose we have in mind will follow the path of the stock induction hose, which is actually a plastic piece on the stock ST. Before beginning our silicone project, we needed a fixture that would serve as a base for the silicone layers that will be applied. After making a model in Solidworks, we fired up the 3D printer and watched

Now that we had a ton of information and data points for the stock intake system, it was time to begin creating our own design.

Piping Fabrication

We're starting our intake system at the turbocharger and working to the airbox. We intend to place our box in the same location as the stock unit so we can take advantage of the stock cold-air duct.

We switched on the band saw, fired up the welder, and started tackling the route for our prototype pipe. Our first length runs from the turbocharger around to the rear of the valve cover.

Prototype Fiesta ST parts

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

Automotive passion has evolved over the years, and is still very much alive and well. A lot of this is a result of automakers continually bringing us the best in technology, innovation, and performance. Some will complain that modern automobiles are numb, boring, and full of complicated electronics and gizmos. Whatever your take on this is, one thing is certain. People still love cars, and the impulse to modify vehicles is as strong as it has ever been.

Take the Fiesta ST for example. A compact hatchback, front-wheel drive, economical vehicle. A few bolt-on modifications can turn this into a tire-shredding, corner-carving autocross monster. It is all in how you approach new technology. You can embrace it and take advantage of what we have available in today's age, or you can curse electronic fuel injection, discredit independent rear suspension, and continue to rip around your hometown streets in your SBF-powered Cougar. Not that there is anything wrong with this. The key here is acceptance,

Mishimoto Ford Fiesta ST Oil Cooler Kit

Testing time! It's always fun to see the results when you make changes to your vehicle, whether bolting on a new wheel and tire combo, or installing a  new set of  dampers. In this case, we are expecting our Fiesta ST oil cooler setup to drop fluid temperatures by a substantial margin during our on-road testing.

Testing Setup and Conditions

Testing the stock Fiesta ST oil cooler is relatively simple. Only one temperature and pressure will need to be monitored, so we can utilize our sandwich plate sensor adapter shown below.

After removing both catch cans for data collection in our previous post, we discussed the idea of relocating the bracket that holds the PCV catch can to a different area in the engine bay. We mentioned earlier that we were toying with the idea because the current location of the Fiesta ST catch can raised some concerns. One of them being that the current location for the catch can would interfere with right-hand drive (RHD) applications of the Fiesta ST, and we want this catch can to be all inclusive. In addition, it came to our attention later on that it would also interfere with some aftermarket intakes.  We try to take common Fiesta ST parts upgrades into consideration so that the products we make will fit all Fiesta STs. The consensus was that because there was a bit more room further forward in the engine bay to relocate the catch can, that would be the way to go.

Bracket and Hose Setup

With this new location in mind our engineers began fabricating a

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!).
