Power without compromise
PES is proud to introduce our latest Whipple based supercharger systems for the Audi B7 and B8 RS4. The new system uses the highly regarded Whipple 140AX 2.3 liter twin screw supercharger at its heart.This screw compressor is by far the best supercharger available today. It’s the only supercharger to provide a positive displacement design for maximum low-end torque as well as high efficiency for maximum top-end horsepower. No other supercharger in the world can offer the same unique benefits. The resulting power is impressive...
B7RS4 - 595 HP and 530 Ft/lbs torque
RS5/B8RS4 - 600HP and 515 Ft/lbs torque
Many months were spent in CAD after 3D laser scans of the engine were completed. Designing a very efficient manifold design around this very large supercharger given the extremely limited space available in the engine compartments was quite a challenge. In the end we were able to meet the challenge as well as exceed a few design goals such as fitting 2 very large air to liquid intercoolers in the manifold runners which achieve a huge amount of cooling area. The entire manifold upper section, runners and inlet are CNC machined from solid billet aluminum. The finished parts are powder coated in your choice of red/black or silver/black. Custom color requests are also possible.
B8RS4 Note: Due to manufacturing tolerance variations of the stock high pressure fuel pumps some B8RS4's will require a high pressure fuel pump upgrade.
