Supercharger Upgrades for your MINI Cooper
A pulley or supercharger upgrade can increase airflow and create room for more power. We help choose suitable parts and check the cooling, fuelling and tuning needed to support the change.

What a supercharger upgrade can offer
Changing the pulley ratio or supercharger can supply more air to the engine. The choice also affects how fast the supercharger turns and how much heat it produces.
- Pulley sizes need to keep the supercharger within its intended speed range.
- The intake and bypass valve, which controls airflow around the supercharger, affect response.
- Cooling and fuel supply help determine how much of the extra airflow the engine can use.
Supporting upgrades
We will check the belt drive and cooling system alongside the proposed pulley or supercharger change.
- The pulley alignment, belt and tensioner need to suit the installation and be in good condition.
- The intercooler, cooling circuit and intake may need changes for the planned power level.
- Fuel injectors, pumps, transmission capacity and ignition parts where applicable also need to suit the finished setup.
Custom tuning and dyno testing
We adjust the tune for the extra airflow and check how the car performs as temperatures rise over repeated dyno runs.
- Testing covers the air/fuel mixture, intake temperatures and engine load, with ignition checks where applicable.
- We check for belt slip and confirm that the bypass valve and fuel supply work as intended.
- The final tune needs appropriate limits for torque and temperature.
