With well over a decade of experience, the tuning experts at M7 have carefully hand-picked the components for each kit so that they work in harmony to produce the highest power levels. They are also designed to meet strict reliability standards.

M7 prides itself on using only the finest materials to produce their products. We carefully select our partners that meet our same strict standards. You can count on every part in our kits to be of the best quality and design, regardless of price.As a bonus, each kit is priced to save you money when compared to buy the parts individually.

About our 16% Pulley When M7 was looking to add a pulley to our existing product offering, we realized that it had to be better and have that M7 "out-of-the-box" engineering and mindset. The M7 Supercharger Technology Pulley features a 16% reduction and a number of improvements over stock and other aftermarket pulley designs.Our revised design for 2014 allows the pulley to be easily positioned deeper onto the supercharger shaft for proper belt alignment. We added shoulders to the outside of the pulley to help prevent the belt from walking off of the pulley surface if you have a weak tensioner or the belt stretches at extreme RPM events. Our proprietary taper-loc shaft locking system offers the highest locking force to the supercharger shaft at the lightest weight. The M7 taper-loc is superior to any other design on the market....PERIOD! This high grip taper-lock system offers both ease of installation and slip free supercharger performance. By design, the assembly is 100% balanced out of the box. The drive belt grooves are machine to exacting SAE-J1459 specifications.

The M7 SC Overdrive Pulley also incorporates an active cooling system that pulls in cool air through the holes in the pulley shoulder, keeping belt temperature down. Made from high quality aircraft grade billet steel and gold zinc plated for corrosion resistance and years of trouble-free performance. 

About our 0% and 4% Crank Pulley  This beautiful design is a result of extensive computer modeling and CNC machining. A hard anodized coating was added to protect your investment from the elements and ensure a lifetime worth of use. The V-Belt grooves are machined to exacting SAE-J1459 specifications for minimum belt slippage at maximum boost. At 0.99 lbs, the lightweight M7 4% Crank Pulley assists in reducing rotational mass, which in turn increases horsepower, torque and throttle response. Use this in combination with the M7 16% Supercharger Technology Pulley for maximum performance and boost yourself to the next level of MINI tuning and performance. Now comes with a brand new high quality ARP bolt and hardened washer for an extra level of assurance.

  • Standard Heat Range: Best choice for daily driver with minor engine modifications
  • +1 Colder Heat Range: Recommended for agressve driving and cars with engine mods such as 16% & 4% supercharger pulleys, Bytetronic ECU Tunes, cat-less free flow exhaust system with header and high RPM operation.
