    • Introducing the world's most powerful Porsche 911 Carrera and 9A2B6 - 668 rear wheel horsepower PorscheBoost Project 991.2 Carrera

      Well, the latest round of tuning by Gintani is complete and the Tial Porsche 991.2 hardware suite is maxed out on the PorscheBoost Project 991.2 Carrera. In the process new world records were hit making the car the most powerful 911 Carrera and 991.2 3.0.


      The new 9A2B6 3.0 record for wheel horsepower is 668.9 and the record for wheel torque is 612.9 lb-ft:


      Mods:
      Gintani custom tuning for BoostAddict/PorscheBoost
      TiAL M660 Turbos
      TiAL Intercoolers
      TiAL Inlets
      TiAL Plenum
      Fabspeed headers
      Fabspeed bypass pipes
      Meth kit

      More than enough power to give a Porsche 991.2 GT2 RS a run for its money or a tuned 991 Turbo S considering the Carrera is a much lighter package.

      This was achieved on VP110 race gas. We all wanted to clear 700 wheel horsepower but the turbos were already being pushed hard. Boost was dialed back a bit for a reliable setup that would not push the turbochargers out of their efficiency range.

      E85 originally was used but as power climbed to the upper 600's the fuel system became taxed on ethanol. We now know the reliable limit is going to be the lower 6XX wheel range on E85. The factory fuel system will support ~700 whp on race gasoline.

      As for the PDK, the stock clutches are in use. Why? We do have a Dodson upgraded PDK clutch pack ready to go in but TCU tuning allowed us enough clamping pressure to use the factory PDK. That drops the cost considerably and increases reliability for PDK owners who want to duplicate this setup. You will not need to upgrade your transmission hardware to hit this output. You will need quality TCU tuning.

      What is next? GPS numbers and dragstrip numbers. Hopefully a few more world records to join in short order.

      Additionally, a Stage 2 turbo setup is being considered and should Tial/Boostaddict agree Gintani will be tasked with tuning it and a port fuel injection system for 100% ethanol will be added. The Dodson PDK would then be employed and we would see how far the stock rods and engine internals can go. At that point, the sky is the limit.

      Great work so far but we are hardly finished! Thank you to Alex at Gintani whom I gave a hard time regarding the TCU and Jonathan at Aviva as well as the guys at Tial.

        It's not as much money as people think. The turbos are ~$3700... damn good value.

        yah but the intercoolers are also $3k retail the headers are $2k retail and the rest another $2k so all in itís about $11k worth of parts alone.

        Still i agree itís a great value for turning a base carrera into a gt2 competitor.

        Well, sure, but I mean we're talking less than $10k for a huge boost. You don't need the headers or plenum to make big power. You can even do well over 500 wheel with just the turbos and meth like I was running early on.

        I was going to make that exact comment... You can get 80% of the gains for 30% of the cost going this route.

        Congrats mate! Good results! Can't wait for Draggy numbers.

        On what boost did you get it?

        Congrats on the number! Can't wait to see driveability feedback as I was told that TCU tuning would make the car jerking a bit. No proof just words from a reputable builder. It sucks so hard that neither MoTec nor Syvecs releases theirs!!!

        You're looking at least 20k including labor. I would do it again with a base manual C4 though.

        Don't know where you got $20k from. That's way off.

        To match your setup of course....Let's see...

        Cobb A/P $1895
        Protune $900-$1000 (could be lesser/more depending who you use)
        Tial Plenum - $2500?
        Tial Headers $3500?
        Intercoolers $3,000
        Turbos $3700
        Exhaust $5000
        Dyno fee and labor $3000?

        That's excluding meth system.

        Yep. Gintani will dyno tune your car. The price depends on options but let's just say $2k.

        No. $980

        I'm running Fabspeed. $2300

        Yes, these are expensive. $3200

        Most powerful, best priced. How about that?

        Click here to enlarge Originally Posted by quattr0 Click here to enlarge

        I have a modified factory PSE. $0

        Don't know. Labor will vary.

        Anyway, adds up to much less than $20k.

        Also, like I said, turbos are the biggest difference maker. If getting a tune might as well just get turbos + tune. Rest of your hardware can stay stock and you'll still be making 550+ easy.

        This is awesome Joe, congrats on everything. Really cool that it's working out with just a TCU flash so far and that Alex got it going!

        Thanks.

        Now to have some fun and then maybe onto Stage 2.

        I think people are going to realize this is a strong platform. And tons of fun to drive!

        Great setup. Must be a hoot to drive! And understated too considering it doesn’t look like a Turbo or GT2, I like that.

        Have you driven the car yet? It would be awesome to get a set to stickies on it to drop a 9.99
