    • AMS Alpha 9 Porsche 997.2 Turbo vs. bolt on E85 GT500 Predator from a roll

      The GT500's sure are going to be a handful. This Porsche 997.2 Turbo certainly is no slouch with an AMS Alpha 9 package (750+ awhp) but it is a manual transmission example. It certainly looks like shift speed plays a large part in its demise.


      This GT500 recently set the Predator V8 platform quickest and fastest records so it is roughly a 145 mile per hour car. In this video though it has a 2.65 pulley and not the 2.5 it ran for the records.

      You see the Porsche start well but as soon as it shifts it falls back. The GT500 just keeps pulling and makes seemingly easy work of the 911 Turbo.

      Let's see some runs against PDK variants.

      GT500 mods:

      2.65 pulley
      Lethal race pipe
      1050x injectors
      E85 tune from Palm beach dyno

      Porsche 911 mods:

      AMS Alpha 9 package
      Intercooler upgrade
      Fuel system
      Stage 2 clutch
      Stock engine
      MS109 race fuel
      20-24 lbs of boost
      750+ WHP
