for your petrol Land Rover
The 4.2 Litre Jaguar engine fitted to the Range Rover Sport and LM models offers excellent all round performance. However, the tune is set for “average” conditions and there are therefore some compromises in terms of power output.This will be particularly noticable when towing, or in extreme driving conditions.
Supercharger upgrade stage 1
Graeme Cooper Automotive now offers a stage 1 upgrade for the standard supercharger. A “stage 1” upgrade comprises a new pulley kit at around $500 for owner installation, but for an additional cost, GCA will fit and tune the installation.
This “stage 1” version generates significant torque increases, right through the power range, providing stronger accelleration, overtaking-ability with minimal change in fuel efficiency. (typically less than one-half litre per 100 Km) This is the most practical and cost-effective upgrade
