Process West was established in 2003. The business has seen continual rapid growth and we now have approximately 95 distributor/resellers worldwide. In April 2012 we moved from our old 180m2 workshop to our brand new 900m2 factory. We specialise in the design, engineering and manufacture of small heat exchange products and other aluminium products for the automotive industry. Managing director Kevin Westblade has been designing cooling, intake and fuel systems for 25 years. With years of experience in the heat exchanger industry and traveling around the world to various heat exchanger manufacturing plants means that Process West uses only the absolute best available heat exchanger core and manufacturing processes. We use the latest state of the art tig welding equipment and HAAS CNC vertical milling and lathe machines

The goal when developing our new top mounted intercooler was to make it the very best aftermarket top mounted intercooler for WRX/STi... period.

We studied our competitors products and fixed all of the mistakes they have made...some of them major.

The most obvious error that EVERY one of our competors makes is not supplying their intercooler with proper ducting/shrouding to suit the increased size of the new intercooler. There is no point in installing a larger intercooler and leaving the factory under bonnet splitter/shroud in place. Here is the solution. A properly sized splitter/shroud to suit the application.

The next major problem that we see competitors doing (and they all copy each other) is building an intercooler that is too thick. Their design criteria is spot on for bragging rights whilst marketing. They say that bigger is better. This is totally not the case with an intercooler that is mounted at 90 degrees to the ambient air flow.

For good heat exchange to take place you need good ambient airflow through the intercooler. In the case of the boxer engine with its intercooler mounted under a bonnet scoop the ambient airflow speed is already struggling after doing a 90 degree turn through the scoop. The last thing it now needs to do is find its way through 114mm (4.5in) of intercooler core. This will result poor heat exchange and high inlet temps.

Our intercooler is 90mm thick (3.5in) and in turn the intercooler breathes, gives lower outlets temps and in turn more power.
