Hot off the Press – We are pleased to announce the newest product from Process West, the KHANACOOLER Intercooler.
The new and highly anticipated ‘straight-fit’ Intercooler, the Process West ‘KHANACOOLER’ is here now. Taking the technology used in their world-leading VERTICOOLER system and integrating it into a conventional Top-Mount setup for ease of fitment and factory-style appearance, KHANACOOLER represents a fantastic first step into the world of Subaru modification.
- High Flow Process West Bar and Plate core
- Core Dimensions 347 x 225 x 100
- Compatible with factory charge pipe or can you add the Process West charge pipe
- Clean and efficient one piece under hood duct
Rather than gather a single set of data they decided on a two-pronged testing approach for KHANACOOLER to precisely measure and monitor the results of its fitment. First up was the fitment of a latest-spec AIM Data Logging system.
Using data gathered from the AIM Logger they checked how the KHANACOOLER compared to the stock piece under real-world conditions. This way they could measure the effect of heat soak when stationery right through to the not easily simulated wind-load from high speed runs. In each and every test discipline KHANACOOLER showed significant and measurable improvements over stock that you can feel through the seat of your pants while driving.
Strapped to a Mainline Chassis dyno (well known for their accuracy and repeatability) their first test was to perform totally cold runs between KHANACOOLER and stock to show the gains that come from less boost restriction alone. Impressive? You bet, just check the Dyno!
The graph below shows factory intercooler testing after three back to back pulls on the Dyno. Green trace shows intercooler outlet temperature topping out at massive 57 degrees Celsius.
Then with KHANACOOLER installed they perform the exact same test with the same time between runs to show the improvement in heat rejection. The final figure is 30 degrees Celsius, which is a 27 degree Celsius improvement over stock. Regardless of whether you speak in Celsius or Fahrenheit that’s a whopping 48% cooling improvement shown along with a substantial power gain to boot!
All of thei scientific testing points to the fact that when you install the KHANACOOLER and combine the real-world benefits of temperature drop AND pressure drop that saying KHANACOOLER is a 50% upgrade over factory is probably a modest statement!
