Mini Cooper M7 Tuning R53 16% Supercharger Pulley on 2040-parts.com
Ridgewood, New York, US
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.

Renault Twingo concept
Fri, 06 Oct 2006Renault has shown a production preview of the next Twingo, due to be replaced early next year. The new car eschews the monovolume of the outgoing model for a more conventional two-box, with friendliness being replaced with dynamism in the front graphic. This sporting theme is furthered by the dropped ride-height and large arches, and is complemented by a music theme.
DIY Car Repairs in London
Mon, 11 May 2009DIY car repairs in the dry are now a reality in London In those days I would have given anything to have access to a warm, dry garage, with hoists and tools, where I could turn up, fix what had to be fixed, and stay dry in the process. Well, the days of laying prostrate under a car in the freezing cold are long gone for me, but for many, especially in these difficult financial times, DIY car repairs are a necessity. So there should be a bit of a cheer going up in London today as what are believed to be the first DIY garage facilities in Europe open for business in Acton, North London.
