Cooler Than Winterfell – Intercooler R&D, Part 2: Prototype Core

It looks like mother nature is giving the tell-tale signs to us gearheads that it’s time to get ready for track season. The weather is getting warmer and tracks all around the country have kicked off calendar seasons with maiden 2017 events already in full swing. 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 – 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 ››

The Final Product – Focus ST Intake, Part 4

We have an update for our Focus ST intake project! Our first production sample has finally reached our R&D facility, and we have been able to test fit it onto a 2013 Ford Focus ST. Fitment was spot on, and we were able to get all the components properly snug into the car. We made some minor adjustments from our initial design and we included an awesome new feature that will help accommodate more Focus ST’s on the road, so let’s check it out!

It’s the Little Things

During the time we were updating our design, we discovered small differences between the … Continue Reading ››

Dyno Testing and Results – Focus ST Intake, Part 3

We have some dyno data for this Focus ST Intake! Along with sharing our performance improvements, we also have video clips of the intake lid both on and off, so you can clearly hear what is going on while the engine is under wide-open throttle. Our test vehicle is bone stock, with no aftermarket Focus ST parts, allowing us to provide a nice baseline for performance gains against the stock intake.

Results

In addition to using a fully enclosed airbox, the full 3 inch diameter piping extending all the way to the turbo ensured smooth, clean, and ample airflow. The … Continue Reading ››

Fabricating the Prototype – Focus ST Intake R&D, Part 2

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 … Continue Reading ››
