    • Dyno testing the Eurocode/SRM Audi 2.5 TFSI throttle body pipe & IC outlet pipe upgrade for the 8V RS3 and 8S MKIII TT-RS

      There is a 30-minute video that accompanies the testing results but for those who do not have a half-hour to spare AudiBoost will summarize what you need to know. Essentially, the 2.5 TFSI sees a restriction with the factory elbow pipe and the Eurocode/SRM pipe is aerodynamically engineered to improve flow.


      Plenty of data is provided and you will see gains through the curve although the meat of it is in the mid-range:

      Max gains on Stage 1 91Oct out of 4 runs near redline
      These value are for Horsepower and Torque increase to the wheels, see graphs.
      21HP & 26lb/ft TQ @ 4150RPM Run 1
      18HP & 15lb/ft TQ @ 6350RPM Run 2
      15HP & 13lb/ft TQ @ 5950RPM Run 3
      14HP & 12lb/ft TQ @ 6000RPM Run 4

      Max gains on Stage 1 E85 out of 3 runs near redline
      These value are for Horsepower and Torque increase to the wheels, see graphs for reference.
      14HP & 11lb/ft TQ @ 6800RPM Run 1
      11HP & 10lb/ft TQ @ 6000RPM Run 2
      15HP & 15lb/ft TQ @ 5500RPM Run 3

      Let's look at Run 1 on 91 octane:



      And Run 1 on E85:



      The gains are not as pronounced on the E85 tune but you still see gains in similar rpm ranges showing the factory piece is a restriction. Going to a hybrid turbo would exacerbate the factory restriction.

      This will work with all factory hardware:

      The part has been aerodynamically optimized with a larger and more constant cross-sectional area, and a very gradual 90 bend.

      It still connects perfectly to all factory parts. Includes a provision for the grommet of the factory engine cover, a connection for the DV hose, the DV actuator, and the pressure sensor.

      We are also throwing in an upgraded intercooler outlet pipe, that does not have a huge dent like the factory one
      It might be interesting to see what a bored out throttle body would do with the more efficient pipe.
