Thanks for returning to the final portion of this build. Now that we have finished testing, it is time to review our data and see the improvements our cooler provided. To start things off, here is a shot of the cooler fully installed!
Let's dive into the data. First, we'll compare the basic specs of our cooler versus the OEM unit.
The Mishimoto intercooler features a 37.9% increase in internal flow area compared to the stock intercooler!
The Mishimoto intercooler features an 80% increase in internal core volume compared to the stock intercooler!
The Mishimoto intercooler features a 79.5% increase in overall intercooler
Testing time! Well " almost. We had a few quick testing details to sort out and some preparations before we actually began. First, we needed to drill and tap the stock intercooler as well as the Mishimoto prototypes so we could install our pressure/temperature sensors. Additionally, we decided to create a shroud for our TMIC fan to ensure that all cores would receive appropriate airflow on the dynamometer.
Tapping the intercoolers for sensors is a relatively straightforward process. We drilled into both end tanks and then tapped them to 1/8" NPT for our sensors. The stock intercooler tanks are thick enough so we could adequately tap them for testing. Check out a few images of our coolers getting this treatment.
Last time, we left you with a teaser of the rendering for our prototype of the top-mount intercooler (TMIC). Since then Dan has been hard at work refining his design. Our team worked up some CFD analyses of both the stock intercooler and the Mishimoto prototype. And, we also worked up a few functioning prototypes so we could begin real-world product testing. This project is moving quickly and our team is rather excited to see the outcome. Take a look at the finalized rendering of our cooler below!
The core we designed is rather dense and features an offset fin style for greater heat transfer contact points. Despite the density, we saw very similar if not better flow results compared to the stock cooler. Take a good look at the comparisons below.
Nothing sets off a Subaru engine bay like a nice beefy top-mount intercooler. Not only does a big TMIC look great, but it is also instrumental for keeping AITs low and your EJ happy. For those seeking low AITs on a stock to mild build, an efficient top-mount setup is the way to go to avoid inheriting the pressure drop and lag from a front-mount intercooler. Not only this, but the TMIC prevents any road (or off-road) debris from damaging your heat exchanger. This is key for those who are involved in any rally, off-road, or rallycross events.
If you keep up with any of our social media outlets, you are likely aware that Mishimoto has been working to develop a TMIC for the 2008-2014 WRX. We are very active within the Subaru enthusiast community, and a majority of our best-selling products are designed specifically for the
