    • 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.

        Hi,

        Does anyone know where I can get a pulley removal tool for this engine? My brother has a 2010 XKR and purchased the package from Eurocharged but can't find the removal tool. ETG had the tool on their wbsite. He contacted tehm and was told they don't sell the tool. Any help is much appreciated.

        Thanks, Ron

        Did you already try asking Eurocharged?

        Yes, they were the first place my brother asked.

        I sent them an email on Friday, I haven't received a response yet. They have it for the 4.0/4.2 but they do not show one for the 5.0. Thanks for the help, I have spent a lot of time searching and I also posted on the youtube video of the pulley replacement on a 5.0 Supercharged Range Rover. I haven't seen a reply on that one either.

        Well we are not quitting just yet. Let's figure out a source for the 5.0 tool.

        That looks like it is for the crank pulley. The supercharger pulley puller that I saw in the videos looks like it fits over the pulley. I saw something similar in a kenne bell website. I plan on contacting them. The supercharger is a TVS 1900. Never hurts to have another tool resource. Thanks Sticky.

        No prob. This should be easier to source.

        I'm sure Eaton could help you as well considering it is their blower.
