    • GAD Motors claims to have a 900+ horsepower Porsche 991.1/991.2 VTG 911 Turbo upgrade

      VTG turbocharger upgrades are fairly rare. Why? The VTG (Variable Turbine Geometry) turbo technology is complex and requires a large investment and a big turbo manufacturer to produce. Only a handful of large OEM's do VTG turbos for gasoline motors.


      That is why when you see a turbo upgrade for the 911.1 or 991.2 Turbo models it usually ditches the VTG system. If not going to all new turbochargers, the cars usually stay with bolt on modifications.

      GAD Motors claims to have a 900+ horsepower VTG turbo upgrade for the 991.1/991.2 911 Turbo platforms.

      They say their turbos are a completely bolt on affair:

      All parts are designed so that they can replace the original parts without further modifications! (Bolt on)
      Hopefully we see these installed and get some dyno runs and performance results to show the upgrade working as advertised.

        I'm wondering how the vanes are shifted, via oil pressure? That's the only thing I could think of.

        This is cool, it seems even in the OEM space, VGT is still relatively rare, Porsche is the only one really making widespread use of it, it seems...at least in the high-performance space. I thought I heard back in the day that VGT was a bit more delicate, which isn't hard to believe, but I wonder if that's why. BMW and MB both seem to be disinterested in it.

        This upgrade isn't what it is cracked up to be but I can't explain it as well as others.

        There is a VTG upgrade on the market that is better than this and doing quite well: https://www.boostaddict.com/content....n-the-1-4-mile
