62 mm Supercharger Pulley – Jaguar 5.0 Supercharged – approx. -6%

Performance pulley with a diameter of 62 mm, designed for the supercharger used in Jaguar 5.0 V8 Supercharged engines.

The reduced pulley diameter increases the supercharger's rotational speed, allowing for faster boost pressure buildup, improved throttle response, and increased forced induction system efficiency.

The 62 mm diameter corresponds to a reduction of approximately 6% compared to the factory pulley. The actual reduction value may vary slightly depending on the version of the factory pulley and supercharger.

This list is for reference only. Individual models and model years may have featured different versions of the supercharger, pulley, and drivetrain.

Compatibility

Before purchasing, you must confirm:

• car model;

• year of manufacture;

• VIN;

• engine version;

• supercharger model;

• factory pulley diameter;

• pulley mounting method;

• number and profile of grooves;

• current supercharger drive configuration.

To confirm compatibility, please send us your VIN and a photo of your current pulley and supercharger.

Working principle

Reducing the diameter of the pulley increases the rotational speed of the supercharger in relation to the engine's RPM.

This can provide:

• faster boost pressure buildup;

• better engine response;

• improved flexibility;

• increased supercharger efficiency;

• the potential for better performance figures after proper vehicle tuning.

The final result depends on the vehicle version, the technical condition of the engine, the supercharger, the fuel system, air-to-air cooling, and engine management.

We do not guarantee a fixed power gain because the effect of the modification depends on the complete configuration of the specific vehicle.

Recommendations before installation

We recommend this modification only for cars that are in good technical condition and maintain proper factory parameters.

Before installation, check:

• supercharger condition;

• condition of bearings and the drive clutch;

• intake system leaks;

• condition of the serpentine belt;

• condition of the tensioner and idler pulleys;

• air filter and filter housing;

• intake air cooling system operation;

• air-fuel mixture parameters.

Contaminants entering through the filter or a leaky intake system can lead to damage to the rotors and the supercharger housing.

Recommended supplementary modifications

With increased supercharger speed, we recommend:

• an efficient and functional intercooler system;

• monitoring intake air temperature;

• using fuel with an appropriate octane rating;

• monitoring engine parameters under load;

• computer diagnostics after the modification is performed;

• individual software adjustment if required by the vehicle's configuration.

Installation

Installation should be performed by a workshop experienced in servicing Jaguar mechanical forced induction systems.

After installation, check:

• proper seating and alignment of the pulley;

• condition and tension of the belt;

• proper belt routing over all pulleys;

• no contact between the belt and other components;

• proper supercharger operation at idle and under load.

The pulley is designed as a direct-fit solution for compatible supercharger versions. The need for a different belt length must be confirmed individually for each specific vehicle.

Package contents

• one 62 mm performance pulley for the Jaguar 5.0 Supercharged supercharger.

The supercharger, belt, installation tools, intercooler, and installation services are not part of the kit unless ordered separately.

Important information

This product increases the supercharger operating speed. Improper installation, a worn-out supercharger, a faulty air cooling system, or incorrect engine operating parameters can lead to component damage.

Before purchasing, please send us the VIN, car model, year of production, and a photo of the currently installed pulley. This will allow us to confirm product compatibility.
