• Eurocharged 2013 Jaguar XKR dyno tune results on supercharged 5.0 AJ133 V8 with upgraded pulley - + 74 wheel horsepower

      The supercharged 5.0 liter direct injected V8 AJ133 motors from Jaguar have quite a bit of untapped potential. This 2013 Jaguar XKR unlocked quite a bit of it with some massaging from Eurocharged. The V8 is in a 510 horsepower state of tune at the crank from the factory and now with the addition of a higher boost pulley and tune is over 500 to the rear wheels.

      The baseline includes an aftermarket supercharger pulley so this car is putting out more than stock. What is amazing is that on top of the pulley Eurocharged pulled another 71 pound-feet of torque out of this car. This resulted in an additional 74.77 horsepower at the wheels.

      Total horsepower is now 530.81 horsepower to the wheels making for a car well over 600 at the crank and much stronger than stock. Those with the newer supercharged Jag V8 should do themselves a favor and get a tune and pulley for a car that feels brand new.
