    • FBO Porsche 997.1 Turbo with Alpha 28 turbochargers pump and MS109 dyno results - 740 rwhp

      The 3.6 liter flat-6 in the 997.1 Turbo to this day is still the aftermarket power champ. The Mezger block based engine does not have direct injection and the 997.1 Turbo did not offer PDK. Sometimes it is best to keep things simple.


      This 997.1 Turbo feature bolt on modifications and a pair of upgraded turbos courtesy of AMS Alpha 28 units.

      On pump gas it makes a respectable 675 horsepower to the rear wheels:


      Output rises to 740 rear wheel horsepower on MS109 race gas. You will notice the gains from the higher octane fuel come past 5000 rpm and result in more power up top.
