    • Porsche 911.2 GT2 RS before and after dyno tune results - +90 whp

      The GT2 RS is already a monster in stock form. On a Dynojet it puts down 683 rear wheel horsepower. In magazine testing it traps 139 miles per hour which is a bit optimistic although it should not be too far off a McLaren 720S which clears 140 miles per hour.


      So what did Cobb get for a baseline on the World Motorsports Mustang dyno? 605 rear wheel horsepower:


      Very stout with a very nice top end power curve too. Look at the tuned gains now and they picked up 90 horsepower at the wheels. Porsche left owners quite a bit to play with.

      Very, very nice and the tuned curve essentially mimics the factory curve but with more meat everywhere.

      This also bodes well for VTG turbo upgrades based on the GT2 RS turbo hardware.

      Great to see a GT2 RS tuned this early and putting up monster numbers on a Mustang dyno on pump gas.
