    • AudiBoost forum member ditches his B8 S5 3.0 TFSI supercharger for a Precision 6466 turbo and makes 488 awhp

      The Audi 3.0 TFSI supercharged V6 platform is somewhat stuck. Sure, there are tuners like APR squeezing every last bit out of the factory blower but the size of that blower is always going to be a limiting factory. Well, why not dump the blower for a turbo?


      That is what AudiBoost member @UkuRiSh did and the numbers are pretty impressive. He's making 488 all wheel horsepower on a Mustang dyno at 18 psi of boost:




      The mods to get there? Extensive:

      J-Fonz Custom tune Single Turbo
      J-Fonz S-Tronic Tune
      3.0 TFSI Engine
      Custom made turbine manifold with 2" SS
      Precision 6466 V band Turbo
      Precision 46mm wastegate
      3.5" Down Pipe
      3.5" Middle pipe
      2.5" Cat Back
      Custom made Cold Air Intake
      K&N Cold Air Filter
      H&R Coilovers
      Cortex EBC Boost controller
      Innovate SCG-1 AFR/Boost
      Stock S-Tronic " looking for upgrade later to performance clutches up to 800lb/ft "
      Custom Dual Supercharger water cooler
      Custom Chiller A/C Refrigerants for Supercharger Cooling
      Custom Transmission oil cooler
      Custom Oil cooler
      Custom Crankcase ventilation with Catch Can
      Custom made A/C Chiller for supercharger
      Autotech High Volume Fuel Pump Upgrade
      Water meth injection
      E85 Bluetooth Ethanol Content Analyzer
      034 Transmision/Rear Diff inserts kit
      KOSO Transmision Oil Temp digital gauge
      Brembo 6 pot from S7,S6 and 400mm brake disk
      Niche M152 Vicenza 20x10.5 5x112 +27mm Gloss Black
      285/30/20 Tires P-Zero Pirelli

      The next step is forged internals and a custom intake manifold with port fuel injection.

      It's hard to argue against dumping the 3.0 TFSI blower for those who want to extract maximum performance from the platform.

      AudiBoost can't wait to see what new heights @UkuRiSh pushes the 3.0 TFSI to.

        I'm surprised more people haven't ditched the SC for tubo. Maybe tuning until now was the holdup?

        With a built motor you are going to set some records.

        Probably yes tuning was the problem, we still discovering ECU/TCU to push stock block over 500-550whp

        Great looking work. Considering how much less stressful making power with a turbo is versus a blower on the motor I'd hope you could push passed that level. Has anyone found the limits of the stock bottom end yet? Looking forward to seeing the results!

        I'm not 100% positive but with good tune and controlled EGT/Fuel can be done 550whp/ 500wtq we will found out soon )
