New supercharger kit from Arden adds 80 horsepwer to select Jaguar and Land Rover models.

Jaguar and Land Rover fans, take note. German tuner Arden has just released its latest supercharger upgrade kit for the Jag/LR V8. The new kit uses an ultra-efficient twin-scroll supercharger with better response. It provides up to 80 additional horsepower and 140 Nm torque, making 550-horsepower upgrades to the XJR and Range Rover Sport possible.

The kit is available for the Range Rover Sport and Range Rover LM equipped with the 4.2 liter supercharged V8. It’s also available for Jaguar models with that powerplant: the XJR, XKR, S-type R and XF SV8.

Arden says the new supercharger kit is self-contained and manufactured to racing standards, and can be installed by most knowledgeable shops. It’s major surgery, but engine removal is not necessary in all applications.
