Add 20 hp to your MINI. CravenSpeed 15% Supercharger Reduction Pulley with hub adapter and four bolts (CRMC-0011). CravenSpeed Quick Puller pulley removal tool to remove your stock supercharger pulley (CRMC-0013). A Gates Micro-V Serpentine Belt sized for the 15% pulley (K060535). Brisk Premium Racing Plugs one heat-range colder than stock (DOR14LGS-T).Smaller Pulley = More Go. Smaller SC pulley spins faster. CravenSpeed's supercharger pulleys are machined to a specific reduction of the original equipment on your MINI's supercharger.
It is widely accepted that these sizes are safe amount of reduction on this style of supercharger. Smooth, form fitting teeth on your pulley take longer to machine but are worth the extra time.
CravenSpeed pulleys will neither eat nor throw your belt. You can be confident your belt will last long, and run quietly. We do recommend using a slightly smaller belt with these reduction pulleys. If both sizes are safe for the supercharger which one should you choose?
The supercharger is only creating boost under acceleration, on a normal or even a spirited drive this is only occasional. However, at the track or an autocross event acceleration is sustained and frequent. If you use your MINI for these types of events, it is better to use the 15% reduction pulley.
This is because the 17% pulley causes the supercharger to heat more rapidly and the warm air begins to negate the positive effects of the extra PSI earlier in the band. Will it work on my car?This pulley kit will work on all supercharged MINI models except the JCW which already has a similarly reduced size (12%) pulley on the supercharger. If you would like to upgrade a JCW MINI, consider a 17% kit instead. If you plan on wrenching on your own, make sure you have a puller designed to remove the MINI's press-fit OEM pulley. See the card included in the pulley box for a link to instructions on CravenSpeed's website. Gates Serpentine Belt for Reduction Pulley (K060535).
If you are adding a reduction pulley, you need a shorter belt. Length of this belt: 1379mm. This kit ships with the K060535 belt. With this tool, you will be able to remove the stock press fit pulley safely, without removing the tensioner. For use in removing stock supercharger pulley.The puller body is made of heat treated carbon steel and has a tooth profile to match the OEM pulley exactly. The center screw is grade 8 quality. Our puller will not bend during normal use, and will last for many pulls. If you would like to remove a JCW pulley, we do offer a tool designed for it specifically. Let us know at checkout and we can make the switch. Only using the tool once?
BRISK Premium LGS spark plug utilizes a very unique, semi-surface discharge electrode design. With this this design, the spark plug is able to fire a much larger spark plug gap, because the spark glides along the surface of the insulator, requiring much less energy than firing a traditional style air gap. Longer spark discharge makes more contact with the A/F mixture, igniting more molecules in the A/F mixture over a larger area. Since the air fuel mixture inside of the combustion chamber is not homogenous (has different concentration at different places), it is beneficial that the spark discharge is not confined to only one set place (like with a conventional spark plug), instead, the spark discharge can occur anywhere in 360 degree perimeter of the BRISK LGS spark plug tip. Due to the large parallel surfaces between the electrodes, BRISK LGS spark plug gap has higher capacitance than a fine point electrode spark plug.
It is easier (takes less energy) for a spark to glide along the surface of the insulator than to break through the air gap. Silver is the best conductor of any metal! It conducts 560% more electricity & 481% more heat than Platinum, and 276% more electricity & 177% more heat than Iridium. BRISK LGS spark plugs offer faster and better ignition of each ignition cycle, thus helping to improve fuel efficiency and fuel mileage. Spark Plug Patented Firing Tip Design, No Indexing or Gapping Required.
Choose the right heat range for your car. Stock R53 -- choose stock heat range (DOR15LGS-T). JCW or 15%/17% SC pulley -- choose one-step colder (DOR14LGS-T). Heavily modified -- choose two-steps colder (DOR12LGS-T).
Let us know if you want a different heat-range plug when you check out. This kit ships with the DOR14LGS-T. See our other listings for different heat range plugs. California residents for off-road use only. Check your local legal requirements if in a CARB compliant state.
