We are nearing the end of this build. As mentioned in the last post, we wanted to put our core to the test and provide some cooling efficiency data that our customers could use. We decided to modify our 2010 STi to add some heat and power to the CAC system for testing. Information regarding our vehicle is listed below.

As promised, we have a couple cool images showing these kits fully installed on our test vehicles. Check them out below!

First, our full kit installed on our shop 2003 WRX Bugeye wagon!

It was now time to test our components and ensure that they were operating to our standards. Our previous testing showed that oil warmup was rapid enough for use on a daily driven vehicle. Next we had to confirm that temperature improvements compared to the stock cooler setup were efficient.

We used a similar testing practice with the previous version of this kit, which includes the procedures and conditions listed below.

Testing Conditions

• Ambient Temperatures: 70°F-75°F
• Driving Conditions: 6 miles of highway driving at 60 mph
• Sensors: PLX temperature sensor reading 10 times per second

Now that we had our battery tie-down finalized, we could focus on the next component we wanted to tackle in the engine bay. Our next target would be the radiator stays, the small stamped steel pieces holding the radiator to the radiator support. We offer anodized aluminum radiator stays for a variety of vehicles including the previous generation WRX/STI, Honda Civic, and Ford Mustang.

For this particular project, we would be following a similar route. Our stays would be produced in aluminum and then anodized in a variety of colors to match an engine bay accent color. Before we get into the Mishimoto design, take a look at the stock components.

Mishimoto is not only interested in improving the performance, reliability, and power output of your new Subaru, but we also care about aesthetics. Small touches in the engine bay can make a big impact on the overall appearance and also provide a sense of personalization. Our first targeted component is the battery tie-down. The stock tie-down is rather bland, its main purpose being functionality, which is fine for a stock unit. For those looking to upgrade, a stylish aluminum replacement is ideal. In case you haven't yet peered into the engine bay of your "15, here is what the stock tie-down looks like.

Time to weld up some pipes! This would be the more time-consuming portion of this project, as most of these vehicles would require a specific pipe kit. We would not be able to utilize one set of pipes across the model board, as we did with the intercooler. Going in order, we started with our Bugeye. One of our test vehicles featured a reasonably stock engine bay, as shown below.

Our direction with this project is to develop a thermostatic oil cooler solution for the 2015 WRX. Our team decided to eliminate the factory liquid-to-liquid cooler and replace it with one of our thermostatic sandwich plates. By doing so, we could properly regulate fluid temperatures according to the temperature thermostat installed in our sandwich plate. Additionally, we could provide improved cooling efficiency with the use of our liquid-to-air heat exchanger carried over from our non-thermostatic kit.

So why not retain the stock cooler and make the Mishimoto unit thermostatic? We have a few reasons to back up this decision. First is clearance concerns. When adding a sandwich plate to the top of the factory cooler, the filter is raised as well. This provides a

Time to start designing the basic dimensions of our intercooler! As mentioned in the previous post, this cooler would need to fit with all chassis if possible. Luckily we had a few of these vehicles as shop cars. First up, we pulled our 03 Bugeye Wagon into the shop and began taking a look at the space we had available in order to throw a huge core behind the bumper. Up on the lift she went and the bumper came off to reveal what we were working with.
