Stage 2 Supercharger Kit For The '78 - '86 16 Valve Porsche® 928

I received the kit about 4 weeks after my order was placed. I am an amateur and the install took me about 40 hours, a pro could probably do it in 10 hours. A 70-page color instruction manual made each step easy to understand. Where I had trouble, Carl was there to steer me forward. The parts’ quality and finish is excellent, and the level of design consideration is very high. I spent some time cleaning and painting components, new and old for my install, and the kit worked perfectly on the first turn of the key. The power comes on about 2500 RPM and just keeps building. I am very pleased with this product. John M.
