Due to the complexities and machining time of manufacturing these intercoolers, production runs are limited.


Dyno Testing
In-depth engineering processes and testing alongside leading VAG tuning/supercharger specialists, VF Engineering, and Pacific German allowed us to make this high-level vehicle’s components just as refined as the vehicle itself.

These two graphs show the comparison of OEM (Left) and CSF Intercoolers (Right) with a factory OEM engine tune on an Audi C8 RS6. As you can see from the graphs above, the OEM intercoolers exhibit heat soak early in the testing, already starting to affect performance on the 3rd dyno pull. IATs go up with engine speed. With the CSF intercoolers, the temperature drops as engine speed increases, and recovery between dyno pulls are rapid.


The second set of graphs compares the OEM (Left) and CSF Intercoolers (Right) with VF Engineering Stage-2 engine performance software. In these graphs, like the previous ones, the OEM intercoolers also allow heat to rise as engine speed increases. With the CSF Intercoolers, air intake temperatures drop as engine speed increases. Compared to the OEM intercoolers, IATs are much more stable with the upgraded CSF units.
