THE-RS4, S4 B5, RS6 C5 Upgrade 08 Turbine Housings

Product information:

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 housing is suitable for the OEM RS6 turbine wheel.

We also offer machined exhaust housings to suit,  TTE550 / TTE600/TTE780 / TTE880 /

Advantages over the OEM RS6 Exhaust housings :

• Larger volute (08)
• Flow-optimized design
• Lower exhaust back pressure
• Optimized flow of the exhaust gas level
• Lower EGT compared to RS6 OEM housings
• Higher power compared to RS4 or RS6 OEM exhaust housings
• Larger inlet cross-section matched for THE Tuner exhaust manifolds
• Downpipe flange with double bolt circle (RS4 / RS6)
• Optimized wastegate channel for no boost creep
• 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 942 HP 1273 Nm was achived not using Ethanol. 
• One set includes two turbine housings with installed wastegaste flaps
• Supplied to suit RS6 exhaust turbines

Extra information:

• We recommend using the original Audi bolts and nuts for assembly!
• Installation on the RS6 C5 is only possible in connection with using manual gearbox!
