  1. Cooler Than Winterfell - Intercooler R&D, Part 3: Does It Perform?

    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 of heat transfer across the core.

    One of our newer pieces of equipment is a neat little camera that detects thermal activity. It has been pivotal as our visual aid when looking at heat-soak and dispersion across stock intercooler applications, as well as our upgraded prototypes. We used it on our loaner ST to see how the stock unit handled the heat and how we could make it better.

  2. Testing and Results - ND Miata Intake, Part 4

    Testing and Results - ND Miata Intake, Part 4

    We finally have an update for the Miata intake project!

    With our prototype now in working order, we were finally able to hook up our ND Miata to our dynamometer and get some pulls underway. At this point in the process, we knew we'd want to play around with some other design ideas while the car was hooked up to the Dynapack. AFRs, power output, and sound clips were all on the agenda for the evaluation of this prototype system.

    We did gain some decent performance in the low end of the power band, but the upper end of the curve follows the path of the stock intake system. This graph displays an average of several pulls to ensure that each setup produced a consistent output and plot.

    During our testing with the BRZ performance intake, we found a noticeable improvement in power output when we removed the sound tube. We did runs for the ND both with and without the sound tube and found no difference in performance. The effect of sound tubes on
