    • Cobb AP tuned Porsche 991 Turbo with By Design Stage IV turbocharger upgrade dynos 747 horsepower to all four wheels on stock engine internals

      Well, this some serious power! This Porsche 991.1 Turbo S belongs to PorscheBoost member @Markblackwell. You may remember that a Cobb Tuned Porsche 991 Turbo with this By Design Stage IV upgrade put down 665 to all four wheels earlier this year.


      It seems they figured out some fueling issues (meth probably is helping quite a bit) and the tuning has evolved further as the By Design Stage IV turbo package with Cobb AP tuning managed to now make 747 horsepower to the wheels. Torque is at 715 lb-ft.




      Keep in mind this is on a Mustang dyno. This is well over 800 wheel horsepower on a Dynojet. How the PDK clutches are coping with this much power and torque is anyone's guess and PorscheBoost would guess the transmission will not last long at this level namely if standing launches are involved.

      Porsche 991 Turbo tuning for upgraded turbocharger is certainly coming into its own.
