Completing the Package – Intercooler Piping R&D: Coming in Hot

Fresh off the assembly line comes our prototype intercooler pipes for the 2013+ Ford Focus ST. In the last update, I reviewed the stock piping, our 3D printed prototypes, and mildly teased what the final version of this kit will look like, so it’s time for a full reveal. Let’s go through some of the design features and performance numbers that have resulted from this project.

Cooler Than Winterfell – Intercooler R&D, Part 3: Does It Perform?

We’ve noticed that the 2013+ Ford Focus ST has little wiggle room when it comes to gaining power strictly from bolt-on parts. Even with stage 3 tunes, not many ST’s out there see horsepower numbers beyond 300-350hp. That barrier can be surpassed with the use of ethanol or a bigger turbo, but on a stock turbo and pump gas, those numbers aren’t going too far north. With our intercooler, we wanted to bring on some positive effects for the power in this stubborn 2.0L engine. While power is important, we also needed to monitor the outlet temperatures with a visual analysis … Continue Reading ››

A common mod many of us who are boosted, especially ST owners, want during this time of year is the intercooler. The 2013+ Ford Focus ST features quality design for its the factory intercooler, but improved efficiency is something we like to target. In the last update, we talked about the shortcomings of the … Continue Reading ››

Tank Love – Expansion Tank R&D, Part 2: Final Reveal

I told you this project was going to move fast. In the last update, we laid down our design plans for how we will give this RS coolant expansion tank some sprucing up. Not only did we make the tank more pleasing to look at, we also increased the capacity and added a neat sight tube so you can check your levels with ease. You guys have been asking for it, so let’s get up close and personal. The stock unit pales in comparison to the size of the Mishimoto tank.Continue Reading ››

Tank Love – Coolant Expansion Tank R&D, Part 1: Design Plans

Anyone with a car older than 15 years or so likely has a coolant expansion tank with the structural integrity of wet toilet paper. These tanks rarely get aesthetic love in the factory vehicle design. They are usually plastic, look weird and can start cracking given enough time. After 20 years, the expansion tank in my 1995 Nissan 240SX project car will literally begin crumbling around your finger if any sort of pressure is applied. We don’t want that happening to your RS/ST a decade or two from now, so we decided to design a sweet looking expansion tank that … Continue Reading ››
