Bar & Plate Intercooler |
|
Yet again it is time to upgrade the intercooler,
the Viggen Intercooler is starting to become a restriction. Not just in airflow
but in cooling capacity. The Viggen Intercooler is a ‘Tube and Fin’ style. It
is cheaper to manufacture but has fewer fins and a poor flowing inlet/outlet design.
I installed a custom ‘Bar and Plate’ intercooler. It contains many more heat transfer
fins and a slightly better flow design than the Tube and Fin. It also has 2.5” inlets and outlets.
The result is high boost pressures, less fade and cooler intake air.

| I was able to install the intercooler flush mounted to the Viggen bumper. It fit very well. I made brackets for it that are mounted to the aluminum bumper frame. It acts like a cradle so I did not have to drill any holes or mount directly to the intercooler. Along with being in a great spot for cooling air, it looks intimidating. |
| Below is a cutaway of a Viggen Intercooler. The tubes protrude about ¼” from the base and there are only 10 cooling fins per tube. You can see why this intercooler does not flow or cool well. Pictured next to it is the Spearco core, (my core is the one in the left picture). The tubes are flush for better airflow and there are many more fins to transfer heat. My Spearco Core has over a 60% larger flow area. The stock intercooler has 3.2 sq-in and the Spearco core has 5.3 sq-in. |
