• 957 Cayenne Turbo tuned by Leistung Motorsports hits 553 wheel horsepower on stock turbos with bolt on modifications

      This is incredibly impressive. Keep in mind this is not the new 958 Cayenne (although the motors are very similar) but the previous generation 957 facelift. It has a 4.8 liter direct injected twin turbo V8 that is rated at 493 horsepower which puts down in the upper 300 wheel range to all four wheels in stock form.

      Lesitung Motorsports decided to push the stock K16 turbos further than most and was able to get 553 wheel horsepower which is a gain of over 150 horsepower to all four wheels. This is really not far off some Cayenne Turbos that have been modified with aftermarket turbos. Additionally, this is all done on the stock intercoolers, turbos, internals, and transmission.

      Porscheboost has not ever seen a higher stock turbo Cayenne Turbo dynograph posted. It almost feels like one should be skeptical but the graph says what the graph says. Absolutely incredible results with just minor supporting mods including bypass pipes, intake, and likely race gas as well.

        Would be helpful to see stock dyno overlaid.
