    • Tial Sport upgraded Porsche 991.2 C4S with Protomotive tuning runs 60-130 in 6.90 - M660 9A2B6 turbo upgrade, inlets, plenum, and intercoolers

      It is great to see more and more Tial Sport Porsche 991.2 hardware out in the wild. This is the same hardware utilized on the PorscheBoost 991.2 Project Carrera which PorscheBoost assisted and continues to assist with both software and hardware testing and development.


      Hardware is one part of the equation. The other is software. It seems Protomotive is struggling with extracting power and they are not the only tuner struggling on this platform.

      This car went from 60-130 in 7.40 seconds to 6.90 seconds with the larger turbos:




      The half second improvement is decent and 6.90 is the quickest 60-130 on the platform for now but you expect a larger improvement over the stock turbochargers. Especially since this car now has intercoolers and is running meth injection.

      A dyno post was omitted intentionally as take a look at the previous dyno Protomotive posted with this car. Their power curve certainly could use some work and they omitted showing torque entirely. Why no before/after dynograph posted unless there is something to hide?

      Regardless, as software evolves so will output and performance numbers. Right now to get the most out of the Tial hardware you need a quality tuner and only two tuners to date have posted numbers over 600 whp with these turbochargers. Both of those tuners are in Southern California.

        The Owner of the Car is here on the forums, and the shop that did the excellent install is Driver Source in Huston TX.
        https://www.driversource.com/

        They have a long record of building fast Porsches. They are a Cobb and Protomotive tuner.

        These results are early, but promising.

        Currently has the Fastest. 991.2 60-130. There seems like much more to go too.

        Cant wait to see the Boost addict car after the new tune developments.
        Our test car will be back hopefully soon, and back at World Motorsports / DS.

        Excellent install and some great photos.

        Curious they did not post a dyno though after having a baseline...

        As first post stated, it's in progress so I wouldn't post dyno either. Also, DriverSource has old dyno which you would need to get around to read torque.
