The Powerhouse 650hp JLR upgrade kit turns, what are already exciting cars into truly exhilarating machines.
You can unleash your cars potential with this superbly manufactured kit. We wanted to give you a proper look at what our design engineers have created!


Supercharger Pulley
The Supercharger pulley, also known as ‘upper pulley’ is fitted to the end of the supercharger snout. This new pulley is available on it’s own as an upgrade, but combined with the lower pulley is how to get maximum power.
The smaller diameter pulley means the Eaton Supercharger spins faster – forcing more air into the 5.0 Litre V8 engine!
Crank Pulley
This beautifully machined crank pulley is 15% larger than standard. This seriously increases the torque and on its own, makes the engine feel a litre bigger. Combine it with the supercharger pulley and we’re talking serious power.



ECU Remapping
Once the pulleys are fitted the ECU gets remapped to adjust the fuelling with a precision map. We’ve teamed up with Viezu for the maps, as they have years of JLR remapping experience.
Jaguar Intercooler
For most Jaguar models, we also provide a ‘beefed up’ larger capacity intercooler. These aren’t necessary on the Range Rover models, which have a larger intercooler from the factory.
