Mishimoto Ford Mustang EcoBoost/V6/V8 Aluminum Coolant Expansion Tank

It's hard to match that feeling you get when purchasing a new car, especially the new S-550 Mustang. Picking up your friends for joy rides, melting the tires down the full length of your neighborhood, pulling into the driveway, popping the hood in complete ecstasy " wait " what is that? Is that the coolant expansion tank? Why is it so terrible looking?

This is pretty similar to what happened the day our shop 2015 EB arrived. The engine bay on both the 2.3L and 5.0L vehicles is quite nice, well organized, and clean. Unfortunately, right up front in plain sight sits quite an eyesore in the form of your coolant expansion tank. To improve aesthetics, we decided to tackle R&D to bring you guys a more appealing

Mishimoto Ford Mustang EcoBoost Downpipe!

Opening up the exhaust on a turbocharged vehicle is a great first modification that can make a big impact on drivability, vehicle sound, and driver enjoyment. Typically, a vehicle will see improvements in horsepower and massive gains in torque output. Emissions and sound requirements normally restrict the size and efficiency of stock exhaust systems, which explains why big gains result from enlarging the piping and eliminating or reducing restrictions within the piping.

For this project, we will focus our efforts on designing and testing a new downpipe option for the 2015+ Ford EcoBoost Mustang. Before tackling our downpipe design, we will take a look at the stock unit pulled from our Triple Yellow shop vehicle.

Prototype Modeling

Now that we had a core that was functioning to our standards, it was time to finalize our end tank design and make 3D models to reflect our plans. After some lengthy modeling work, we came up with the renders you see below!

After wrapping up the design of our intake for the 2015, it was time to put the car on the rollers to see if we were making any power gains. As mentioned earlier in this series, we believed that significant power gains were unlikely due to the MAP-based ECU, which is not normally affected by modified intake systems.

Dyno Testing

With that in mind, we strapped the Mustang down and made a few pulls.

Will this cooler be efficient enough to properly handle the heat and pressure created by the EcoBoost? Will we see any power gains during testing? These questions will be answered in the next few minutes, perhaps even quicker if you get scroll happy and skip ahead. Don't ruin the suspense!

Stock Intercooler Testing

First, we would need to capture data from the stock intercooler. We installed bungs on both the hot- and cold-side couplers for our pressure and temperature sensors.

An Interesting Discovery

At this point, our intercooler project took an interesting turn. We wanted to develop a cooler, including going through the process of 3D design, and working up a prototype unit. That said, we had a new idea to get some early baseline testing for core design.

After swinging by our sample room, we retrieved the cooler shown below.

Last time we covered the design of our intake pipe and left you with a look at our airbox design in the form of a rendering. It's time to show you how we developed this component.

First, we started with some steel and began selecting mounting points for attaching our box. Once we found these points, we pulled out the welder and began fabricating a prototype.

With the stock unit out of the way we could begin developing our intake piping. We would be starting at the turbocharger and working outward to an airbox near the stock location.

Using the dimensions from the stock unit, we developed a 3D model of an inlet hose that would be constructed from a silicone material. After completing the model, we produced a unit using our 3D printer.
