VF Engineering is a company that has been developing complete "bolt-on" supercharger systems for European sports cars since 1999. The company is located in Orange County, California, and has a 15,000 sq-ft facility that includes a Mustang AWD 500 chassis dyno, 4 Hunter lifts, a big photo studio, R&D room with a rapid prototyper, and a clean room for ECU board work. VF Engineering's supercharger kits produce a modest 6-9 lbs of boost, which is considered to be a safe level for the stock engine. In addition to supercharger systems, VF Engineering also offers HEX Tuning ECU (Engine Control Unit) Tuning, which is the science of refining the factory calibration of an engine's operation to enhance power and torque. VF Engineering warns that post-installation of their products may require troubleshooting/diagnostics, and components and sensors near the limit of their wear tolerance may need replacement.
