If you are looking for a quick and easy BHP increase for your bmw mini cooper s r53 then this package is perfect for your mini. We have put together a package that consists of the following:


  • Colder Denso Iridium Spark Plugs
  • Reduced size Pulley of your choice
  • Selected GATES belt to fit the pulley chosen
  • Crank Pulley Of your Choice - Should you require
  • Enlarged Alternator Pulley - Should you require

We have carefully selected appropriate spark plugs as well as a belt suitable to fit the pulley reduction and crank as well as alternator or your choice. We have ensured that you have all the right components designed to work hand in hand allowing your charger to work more efficiently and generate some serious BHP for a  seriously competitive price.

Denso Iridium plugs are used as the stock plugs are only designed to deal with heat generated by using the stock super charger pulley. Once a reduced pulley is being used much more heat is generated which can cause the plugs to over heat and fail.

If your opting for a reduced size pulley especially 17% we would always recommend looking tin to changing your intercooler along the line as large volumes of heat can result in power loss and the ECU will limit the cars capability if excessive heat is generated. Driving styles and vehicle use e.g track days do have a large impact.

+2% Lightened and Enlarged crank pulleys as well as Lightened 0% neutral crank pulleys are optional should you require to reduce the weight of the crank further increasing engine uptake and throttle response.

A +5% alternator pulley is also an option as when a reduced sized super charger pulley is fitted the alternator no longer spins at the same speed, generating the same current and voltage. Through fitting the Enlarged alternator pulley to your bmw mini alternator it allows the correct current and voltage to be produced again and helps extend the life of your stock alternator by not allowing it to be span too quickly. If it is span too quickly it can reduce the life of the alternator.

If you are unsure as to the right pulley size for you then please do not hesitate to get in touch an we will be more than happy to help.
