THE-S4/RS4 Upgrade 08 turbine housings
The THE-Upgrade 08 exhaust housing is cast from heat-resistant stainless steel 1.4848 using the investment casting process. They were developed for the S4/RS4 B5 2,7t engine.The machining is suitable for the OEM RS6 turbine wheel. We also offer machined exhaust housings for TTE780 / TTE880. If other processing is desired, this must be carried out by the turbocharger manufacturer.
Advantages over the OEM RS6 Abgasgehäuse:
- Larger volute (08)
- Flow-optimized design
- Lower exhaust back pressure
- Optimized flow of the exhaust gas level
- Larger inlet cross-section
- Downpipe flange with double bolt circle (RS4 / RS6) - when needed the orignal downpipe from the S4/RS4 can be installed at any time (e.g. exhaust emission test)
- Optimized wastegate channel
- Optimized and larger wastegaste flap
Key data:
- More throughput through flow-optimized bionic design
- Material stainless steel 1.4848 (up to 1100 ° C)
- Investment casting for uniform wall thickness and surface quality
- Through continuous CFD optimization, an almost constant response behavior despite the larger volute and a considerably higher peak performance could be achieved.
- The company Reitsamer Performance achieved the previous maximum performance in connection with TTE880 of 942 HP and 1273 Nm.
Scope of delivery:
- One set includes two turbine housings with installed wastegaste flaps
Extra information:
- We recommend using the original Audi bolts and nuts for assembly!
- Installation on the RS6 C5 is only possible in connection with a manual gearbox!
