We are excited to introduce our latest Jaguar performance tuning package: the 465hp Dual Pulley Upgrade Kit. Specifically designed for Jaguar 3.0-liter Supercharged engines, this kit unlocks tremendous power and enhances your vehicle’s performance.
Our 465 kits deliver significant power and torque improvements over stock configurations. Base models can see gains of up to 125hp and 150Nm of torque, reaching up to 445hp without 200 Cell Cats, and over 465hp and 630+Nm of torque with all recommended upgrades.
The dual pulley kits are suitable for most 3.0 V6 Supercharged engines, ranging from 340hp to 380hp versions. While some support is available for models post-2017, we recommend contacting us for compatibility and specific performance gains.
Note: ECU tuning is required for any kit that includes our 15% lower pulley. A handheld tuning module is provided, requiring access to a Windows-based computer to install the necessary software for ECU file management.
If you prefer not to install the kit yourself or lack a local garage, we offer installation services at our Chesterfield workshop. Contact us for more details.
Our tuning kit allows the engine to deactivate the supercharger under partial throttle, maintaining cruise control, fuel efficiency, and comfort during daily driving. However, when you demand more power, the dual pulleys deliver instant torque, transforming your Jaguar into a true supercar. We also provide performance tuning for older 4.0-liter and 4.2-liter JLR models.
Optional Add-Ons:
The included handheld V-Switch tuning module allows you to remap your vehicle without a custom tuner or dyno. Maps provided by Powerhouse and Viezu Technologies ensure optimized performance, backed by rolling road tests. We also offer in-house ECU remapping services.
To achieve maximum power, minimizing intake and exhaust restrictions is crucial. While 200 cell cats help with exhaust flow, consider upgrading your intake system with performance filters and solid pipe conversions to further enhance airflow and engine sound.
Upgrading rear suspension bushes can improve handling by better managing the increased torque, ensuring your Jaguar remains firmly planted.
Our comprehensive kit includes most components needed to reach these power levels. If you prefer less horsepower or already have some parts, explore our individual upper pulleys, lower pulleys, and tuning options. For a dual pulley setup without a tuner, see our 465 kit excluding the tuner. Contact us for more information or with any questions.
