M7 16% SC pulley

Description: 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, in addition to a number of improvements over stock and aftermarket pulley designs.

On the belt-to-pulley interface, M7 has changed the geometry of the grooves, allowing the belt to be in contact with more surface area on the pulley. We also added shoulders to the outside of the pulley to help prevent the belt from walking off of the pulley surface. This in addition to our proprietary V-Groove surface treatment also prevents belt slippage. We also offer the option to add an OEM JCW Pulley belt to further increase the reliability of the pulley system. The overall result: better belt grip.

The M7 Technology Pulley offers an active cooling system that pulls in cool air through the holes in the pulley shoulder and a thermal surface barrier that helps keep belt temperature down.

So why choose a 16% reduction pulley? It is more than the standard 15% reduction and will provide better engine response. Once you incorporate the M7 2% Crank Pulley, your change of accessory RPMs will be even further within safe margins.

Available in silver and polished mirror finishes

Pros:
Cons:

It works, it's round, belts don't slip off. Product does what it should do. Offers a different perspective on smaller pulleys being 16% when the market is filled with 15% and 17% units.

Pros: Power, Sound, Effeciency
Cons:

Simply put, it works. The belt doesn't slip off. It is well made. Gives you a nice boost in power and is neat because it is 16%!
