While examining our existing intercooler, our engineers felt that yet another improvement was necessary. The current core composition was working well for our tests but would likely run out of efficiency with a higher-boost/higher-temperature vehicle. To adjust for this we added more boost tubes, changed our fin type, and increased the density of the fins. Our original cooler featured straight fins; for this test we switched to an offset fin style. The offset fins provide a huge improvement in heat transfer. Check out the images below showing the change.

As mentioned last time, our team decided to make an improvement to our intercooler design. Because of the cast end tanks, we were left with a rather thick inlet. The wall diameter was significantly greater than what we would prefer, and opening up this diameter would only increase flow. The inlet was removed from the intercooler and an aluminum pipe was then welded on. This thin-walled pipe would provide significant benefits in overall airflow.

Armed with a 3D printed prototype and a full day of test fitting, we were able to produce some very insightful renderings of how this intercooler was going to look. Initial flow testing and calculations showed that performance would be ideal for our target power range. After spending some time with Solidworks, Kevin produced the fantastic rendering you see below.

Before we attempted the initial design, we first took a good look at the stock Y-pipe design. Although the spaced ports provide dispersion of air throughout the stock core, we saw immediately that this portion of the design needed improvement.

Kevin, our lead engineer for this project, began by taking measurements of the stock engine bay and intercooler. He used these measurements to begin developing a Solidworks model that would emulate the direction we wanted to go with the overall design. Once the model was completed, it was time to utilize our 3D printer to create a prototype. The initial prototype would be used primarily to test fitment and check clearance before we developed a final prototype. Because this was

The Bugeye, Blobeye, and Hawkeye Subarus have always been a prime choice for a fun daily driver or project vehicle. With a burbley turbocharged flat-four and a robust AWD system, it is hard to beat the overall value of these early models. Nonetheless, the performance aftermarket is massive with documentation available for building your car from mild to wild. Key components to the aftermarket success are the large enthusiast groups such as NASIOC and IWSTI that provide a great place for swapping information on repairs and modifications, and also general discussions about why these cars are so great! These Subarus provide a great base for entry into the racing world, whether it be rallycross, autocross, or track days. Reasonably inexpensive

With positive horsepower data and an impressive intake tone, all our goals were met, so it was time to move towards project completion. We set out to finalize the design, finishes, and construction of our production units and, as you can see below, they turned out quite well. This will be offered in three finishes including polished aluminum, wrinkle-red, and wrinkle-black. Each kit includes an intake pipe with air straightener and MAF housing, a Mishimoto high-flow air filter, a heat shield, a silicone coupler, clamps, and all hardware necessary for installation.

Finally, we come to the sound improvements that the Mishimoto intake provides. Everyone loves a nice throaty intake sound, almost as much as the intoxicating burble from a set of unequal-length headers. During our many dyno pulls, collection of data for decibel strength was something we wanted to explore and compare between the factory design and our design.

It was now time to see the fruits of our labor and collect some data with our revised design. Our poor STI was once again strapped to the dyno (This is what it’s built for, right?) and endured pull after pull as we evaluated power, AFRs, sound improvements, and durability. Weeks of testing resulted in a design that not only pleased our engineers, but also excited them to see some enthusiasts install and use it. Bolting on 25 whp has never been easier, and this intake shows gains through the entire power band.
