It was not there yesterday - those early photo's in this thread are 2 years old.

However I believe it may be related to Ray Fowler. The following was lifted from the PR Technology web site.

Ray is a keen member of the Porsche club of NSW. He has owned several Porsche cars but now concentrates on his supercharged 3.0 litre 911. Ray, as a customer, has had several items from his supercharger project made by PR Technology over the years. These include the blower manifold/intercooler/intake system, the 'free flow' exhaust and the full roll cage. Just fitted is the new PR Technology twin master cylinder brake system to help keep this car up with (and to stop with) the latest of Porsche's finest - hopefully!

Hope this helps.
