    • Pump gas vs. ethanol tuning and the benefits of ditching VTG's - AIM1000 upgraded Porsche 997.1 Turbo makes 746 whp on pump fuel, 1019 whp on E85

      If someone doubts the advantages of ethanol tuning just go ahead and show them the graph below. This is an AIM1000 equipped Porsche 997.1 Turbo which means a built motor and ditching the VTG (Variable Turbine Geometry) turbochargers.


      The factory VTG's work well it is just that when going to for big power at some point they reach their limit. You can only go so big with the VTG's available on the market. Ditch the technology and it opens up a lot of turbo options.

      Look at the results here with pump gas in red and ethanol in blue:


      Night and day, isn't it? Not that 746 at the rear wheels on pump gas is anything to sneeze at. Ethanol tuning takes things beyond the 1000 wheel mark though.

      What about the specs?

      AIM Performance does not share much beyond that other than the turbos being Garrett 3076R units.

      Certainly a monster 997 Turbo.
