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

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,

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.

Interested in purchasing our 6.0L intake elbow?

If you are familiar with our brand, you know we have a vast product line of heat exchangers and associated products available for the Ford 6.0L Powerstroke. We've had great feedback from our customers about our existing products as well as the new products they would like to see come out of our garage. Now that we have our own 6.0L shop truck (shown below), we have easy access to a vehicle for product development and test fitting.

We decided to come up with our own rendition of an inexpensive, free-flowing intake elbow for the 6.0L. Yes, we realize there are ample options currently on the market. That said, we would like our design

If you keep up with the perpetually bustling engineering team here at Mishimoto, you would have noticed our recent projects involving the Focus ST. We could not ignore this vehicle's little brother, the Fiesta, and after numerous requests we decided it was time to start development of new performance Fiesta ST parts.

Before jumping into development, we needed a vehicle. So, we made a trip to the local Ford dealer here in Delaware and drove back in the beauty shown below.

With a solid cooler mounting location in place, it was time to hit the road and collect some much needed data. In the past, we've had great results with our oil cooler kits in terms of temperature reduction, so we have no reason to believe this kit would perform any differently.

Testing Setup and Conditions

Before jumping in the car, we needed to set up our data collection equipment. We use AEM software and sensors to record temperature data for our oil cooler kits. We also use inline pressure sensors to ensure that we are retaining factory-like pressures.

Recording the stock system was easily done with our NPT sandwich plate adapter, as shown below.

After making mockups for our initial setup and evaluating short-term testing data, our team came to a few conclusions. First, we would be incorporating our catch can into the PCV line only. Our brief accumulation test showed that we had substantial fluid accumulation with the PCV line, while the CCV can ended up dry. Second, our mounting location was really subtle and created a factory-like fitment with no visible lines. Last, the ST produces quite a lot of contaminants even in a short period of time, so a catch can is going to be a great upgrade in terms of preventive maintenance.

Bracket Fabrication

Next on our to-do list was final bracket fabrication. Something more stout and aesthetically pleasing were our targets. We would also

Continuing with our progress last time, we were set on constructing a prototype bracket so that we could fully install our system and collect some on-road data.

Cooler Bracket Fabrication

When we left you our team had selected an appropriate cooler location and had started making a bracket template for the heat exchanger. Once we had a general idea of the size, bends, and hole location, we started making a bracket from plate steel.
