HPerformance "air-to-air" intercooler upgrade
We were the first manufacturer in the world to overcome one of the model series' biggest weaknesses and create a unique product for this platform. The RS4 and RS5 2.9 Biturbo model range has a water-to-air supercharger system as standard. This is very efficient for a certain power range, but as soon as the power is increased, the system becomes unbalanced and the water acts as a heat accumulator. The higher the power and thus the boost pressure / air volume increases and the longer the vehicle is driven on the highway or generally under full load, the worse the cooling performance becomes. The intake air temperature rises, the vehicle becomes greasy and performance drops rapidly.
We have the solution. Our large air/air intercooler completely replaces the standard water/intercooler system. This is completely removed and replaced by the HPerformance charge air system. By switching to air-to-air cooling, the back pressure in the charge air system is massively reduced and the efficiency in the form of the charge air temperature remains at an average of 10-15 degrees above the outside temperature, even under continuous load. Thanks to this enormous cooling capacity, all expansion stages, even the standard vehicles, benefit from our cooling system, which is the key to permanently reproducible performance on these vehicles.
- Highly efficient, permanently loadable air-to-air charge air cooling
- Reproducible performance without loss of power
- Charge air volume 350% larger than in series production
- Designed for outputs up to 900 hp
-
Efficient working range up to 3 bar boost pressure thanks to bar and plate network
- Suitable for all power / performance levels on the RS4 RS5
- 100% product control, pressure tested to 5 bar
- Clearly recognizable additional power of 25PS and 60NM in direct 1:1 comparison with the original intake
- 1x HP Sport series intercooler
- 1 x boost pressure hose turbocharger to intercooler
- 1 x adapter for boost pressure sensor CNC milled
- 1 x CNC milled connecting piece
- 1 x silicone hose intercooler to throttle valve
- 6 x stainless steel hose clamps
Important:
Please always have work on vehicles carried out by trained specialists. Bumpers on modern vehicles have various sensors and controls which can lead to problems if handled incorrectly. We do not provide any guarantee / warranty / advice for improper installations. With this solution, the engine software must also be programmed and the water pump of the water charge air system must be reprogrammed.
