SUPERCHARGER UPGRADE PULLEY FOR 5.0L RANGE ROVER SPORT OR VOGUE

Engine tuning is usually expensive and complicated.  However, in the case of supercharged engines it is possible to increase performance just by spinning the supercharger a little faster, generating more boost and power without having to rev the engine any higher.  This is achieved by fitting a performance supercharger pulley.  For Range Rover models we have a range of very simple upgrades which not only give extra power and torque you really can feel, but offer seriously good cost effectiveness in terms of $ per bhp, especially compared to exhaust changes or other conventional tuning.

Pulley upgrades can offer supercharger driven speed increases from 6% to 16%.  It is generally accepted that a 10% blower speed increase on these cars gives about a 2.5psi boost pressure rise, which equates to 35-40bhp (with 40ftlb) improvement on a 400bhp car.

TVS superchargers in the later 5.0  Range Rover models tend to give a wider response across the rev range, with strong gain right to red line.

We supply the highest quality CNC turned stainless steel supercharger upper pulley.

The Eaton TVS supercharger fitted to 5.0 Range Rover Rover models is an excellent compressor, which can be easily upgraded by changing the pulley.  This increases the driven speed of the supercharger, which in turn increasing boost pressure by about 2.5psi, and allowing the engine to produce more power without the strain of revving higher.

Unlike on the 4.2 models which gave mostly midrange power increase, the 5.0 TVS cars yield benefit right through the rev range.  This is a very popular conversion proven by long term success on thousands of cars.
