    • C7 Audi RS7 making 830 awhp, 849 awtq on pump gas with SRM hybrid 4.0 TSI turbochargers

      Huge output numbers here on pump gas from this RS7 tuned by Eurocharged Canada. This Audi C7 RS7 is upgraded with SRM (Silly Rabbit Motorsport) 4.0 TFSI hybrid turbochargers. Keep in mind the factory wastegates are still utilized.


      This is achieved with new Xona center sections that SRM switched to for their 4.0 TFSI turbochargers.

      Methanol is involved here with boost hitting 36 psi and tapering to 32 psi:


      SRM is considering upgrading the in tank pump to run full E85 and crank this beast up further. Additionally, they apparently have an ethanol sensor in the works which should allow for flex-fuel setups.

      The 4.0 TFSI V8 platform is evolving nicely.

        Thx for the info. I guess it'll hold up the same barring hard awd launches.

        Different TCU though. Not sure if these can be programmed.
