Now that we had our first prototype unit in, it was time to evaluate fitment and determine if any changes were necessary when compared to the stock unit. First, we swapped the shrouds to see if any fitment issues existed because of the added size of the Mishimoto unit.

For our third prototype unit for the CVT cooler, we decided to take a more traditional approach. We would place the cooler in a location that would guarantee airflow. The main concern was fitting our large 19-row cooler in a position that would not leave any space for other aftermarket components. First, we mocked-up the cooler and developed some basic brackets that would place the cooler in an angled position behind the upper grille area. Check out a few shots … Continue Reading ››

Mishimoto Subaru WRX CVT Transmission Cooler

After we witnessed reasonable performance gains with our first prototype, we decided to evaluate what we liked and didn’t like with the design. Pros
  • Short line lengths
  • Efficient cooling
  • Compact design and packaging
Cons
  • Did not achieve the temperature decreases we wanted to see
  • Requires wiring of the electric fan
  • Airflow was not as sufficient as it could be
This first design was efficient but not ideal for what we wanted out of the project. To obtain the desired cooling benefits, the addition of an electric fan was necessary. … Continue Reading ››

Welcome back! The quest for low transmission fluid temperatures continues. Once we developed our goals and plan of action for this project, our engineering team went to work, grinding, welding, bending, and cutting. Our first prototype design was quite unique. We mounted one of our 19-row, stacked-plate fluid coolers next to the liquid-to-liquid transfer unit. This is the same location as the turbocharger on the previous generation of EJ engines. Check out the beginning of the mock-up below! [caption id="attachment_1114" align="alignnone" … Continue Reading ››
