In this installment we will be taking a look at the Process West top mount intercooler for the 08+ WRX. I will be taking a look at the stock TMIC first, then the Process West TMIC under the same conditions. Now this will not be a true performance indicator, but it is just taking a look at the heat soak characteristics of the product, which in turn will have some impact on performance.

The WRX will be subjected to extended idle times of 20 min after operating temperature has be reached. The hood will remain closed until the infrared camera will be in use. The outside temperature is 38F. The temperature is very low and should be noted that his will not be typical results that you will encounter during any other time of year. Another important factor to remember is that these are results with thermal products in use so these results are almost a best case scenario with the outside temperature and the thermal products at work under the hood.
The OEM TMIC hot side also has DEI's gold foil on it.
Now after looking at the Process West TMIC installed, the unit is a far superior product compared to the stock TMIC. The core itself should resist heatsoak better than the OEM TMIC. The plastic end tanks of the OEM TMIC are made of some kind of plastic resin that is black in color, which is a poor performing color under the hood. Now initial concerns of the Process West TMIC kit is the black silicon hoses used on the ends of the TMIC. The placement also on the hot side locates the hose directly over the turbo, which would directly impact temperature performance. First lets take a look at the OEM TMIC through the eyes of the infrared camera.
This next image gives you an idea of how much heat is radiating from directly below the TMIC
Now on to the Process West TMIC images.
