The MINI N14 engine uses a traditional pencil coil design that operates using conservative dwell times and relatively low discharge energy. On stock vehicles, this system is sufficient. However, as cylinder pressures increase via higher boost, upgraded turbos, or ethanol-blended fuels, the strength required to bridge the spark gap increases substantially.
Under these conditions, standard N14 coils reach their electrical limits, resulting in high-RPM spark blowout, misfires, or reduced flame front propagation. To solve this issue, our team engineered the B-Series Coil Conversion Kit, which adapts modern BMW B48/B58 ignition technology to the N14 using proprietary brackets, standoffs, and wiring harness adapters. Our performance B48 ignition coils feature a significantly lower primary resistance and an optimized secondary winding structure, allowing them to store and release up to 2.3x more spark energy than the factory N14 ignition coil.
This clean, coil-on-plug upgrade drops directly into your valve cover without bulky external boxes or messy wiring. Whether you need an ignition service or are building a tuned N14, upgrade to B-Series ignition coils and experience improved spark energy and long-lasting performance.
Upgrade your Mini's performance with the ALTA Lightweight Crank Pulley (LCP), designed to increase horsepower and torque. Available in two sizes - 0% Stock Sized and +2% Oversized - this pulley is engineered for Supercharged Cooper S models. Crafted from 6061T6 aluminum, the ALTA pulley is lightweight, weighing just 0.65 lbs, providing a weight reduction of over 2.3 lbs compared to the stock crank pulley.
Crafted from machined 6061 billet aluminum, the ALTA Performance Pulley Removal Tool is specifically designed for the non-JCW MINI Cooper S, offering a convenient way to enhance power quickly and effortlessly, whether you're in a workshop or your backyard. This versatile tool ensures durability and can be utilized repeatedly with proper usage, maintenance, and care. An essential addition for MINI specialty shops, this tool is compatible with all OEM-sized pulleys, except for JCW variants. Note: A steering wheel puller is necessary for the removal of the stock supercharger pulley.
Crafted from lightweight 6061T6 aluminum, the ALTA SC pulley body reduces the supercharger's rotational inertia, significantly enhancing your Mini's engine responsiveness. This innovative pulley design integrates cross-drilled holes to amplify belt grip and mitigate belt slippage, especially during belt stretching. Furthermore, it incorporates oversized belt retainers to prevent belts from jumping off. Available in two sizes—15% and 17% reductions—the 15% reduction option, a market standard, delivers safe power gains of around 20WHP, ensuring a smoother and enhanced performance.
