Old Dog, New Tricks – Intercooler R&D, Post 1: A Core Review

Everything about Ford’s Super Duty Powerstroke brand screams, well, Super Duty. It has done so since they were first put in the Econoline Vans in the mid ‘90’s. Our 2011 is equipped with the 6.7L turbodiesel V8 engine, and it’s clear Ford has engineers who really took the Super Duty term to heart. There are two batteries, two radiators, two thermostats, two coolant expansion tanks, an engine oil cooler, a transmission oil cooler, an EGR cooler – this truck even has a fuel cooler. Just looking at the engine bay of this monster can be a bit daunting, especially to … Continue Reading ››

Pipe Down! Mishimoto Fiesta ST Charge Pipe R&D, Part 5: Prototype Testing

We are nearing the completion of this project. Our engineering team is ready for dyno testing that will verify any power gains made with our larger-diameter intercooler piping. Exactly how much larger is the piping we designed?

The Mishimoto hot-side design provided the greater increase in volume between the two, coming in at a 51% increase over the stock pipe. Fiesta ST charge … <a href=Continue Reading ››

Pipe Down! Mishimoto Fiesta ST Charge Pipe R&D, Part 4: Prototype Test Fit

A few weeks ago we completed our first set of prototype pipes. After a quick evaluation by our team, it was time for a vehicle test fit. Last week we set our Fiesta ST (FIST) up on a lift and began swapping the stock piping for our components. First, the hot-side pipe was bolted into place.

Pipe Down! Mishimoto Fiesta ST Charge Pipe R&D, Part 3: First Prototype Evaluation

Good news! Our first prototype intercooler pipe kit is complete. We can now evaluate both fitment and functionality on our Fiesta. Let’s take a look at each pipe we created.

Prototype Cold-Side

First we have the more complex pipe of the pair, the cold-side.

Complexity comes in the way of multiple bends combined with numerous pipe-mounted features. To the right side of the pipe, you can see the flat flange that serves as a mounting point for the factory pressure … Continue Reading ››

Pipe Down. Mishimoto Fiesta ST Charge Pipe R&D, Part 2: Cold-Side Prototype Fabrication

Stock Cold-Side Features

We had it pretty easy during the design phase of our hot-side intercooler pipe. A simple design with relatively common features, not overly complicated. The cold-side is a different story.
