Shopper Award

When M7 Speed was looking to add a supercharger pulley to our existing product offering, we realized that it had to be better and have that M7 advanced engineering and mindset.

The M7 supercharger 16% speed increasing pulley will add low end power, enhance street drivability and improve on-track performance of your MINI. For 2014 a number of improvements over stock and other inferior aftermarket pulley designs have been made.

So why choose a M7 Speed 16% reduction pulley? It offers a superior shaft locking system, super light rotational weight, active cooling and it is designed to run flush to the supercharger housing for perfect belt alignment and reduced belt and shaft loads. No other pulley on the market offers all these features. Add a M7 Speed 4% crank pulley and you have the ultimate power adder supercharger drive system available anywhere on the Planet!
