World's most powerful X5/X6: BMW F85 X5M with PPM Racing built S63TU V8 and K8 Strasse tuning tops 1116 horsepower

[Sticky]

You may remember last year the X5M cleared 1000 horsepower at the crank for the first time. Well, that F85 X5M with a built S63TU V8 courtesy of PPM Racing Australia is now making 1116 horsepower and 1028 lb-ft of torque.

How? Good question. We know it has PPM pistons, rods, and a forged crank. It is at the stock displacement but it is getting a PPM 5.0 liter S63TU stroker setup next.

How is it fueled? What are the turbos? How is the transmission holding together? All good questions for Russian tuner K8 Strasse who provided the following info:

- K8 Strasse Tune
- Twin BorgWarner Efr 7163 turbos
- K8 Strasse fuel system
- K8 Strasse cooling system
- Forged Pistons and conrods from PPM Racing, dropped compression.
- Porting GBC.
- Full catless Akrapovic exhaust

We still don't understand how the transmission is holding together considering they claim it is stock.

Apparently it will do 100-200 kph in 5.2 seconds:

This is the baddest X5M or X6M out there as far as BimmerBoost knows.
