CS400 is PSI’s first tuning project for the 997 Porsche and the car that will introduce the company to the North America. To produce 400 horsepower, PSI take a standard Carrera, add their own intake, exhaust and control unit. These components benefit from PSI’s motor sports program and provide a foundation for the company as both a tuner and a race team.
Since 1998, PSI have been working with Porsches, contesting them in the French and Belgian GT championships. By 2001, the Belgium-based company started offering tuning programs for the 996 range. Those developments reached a climax with the PSI Porsche GT2-R having 720 bhp @ 5500 rpm.
For 2005, PSI offer an Engine Kit for the 997, which consists of an air box, sports air filter, intake manifold, headers, catalytic converters, rear mufflers and a reprogrammed engine control unit. The newly developed body kit features bumpers, a front splitter, rear diffuser, and a giant wing made in carbon fiber.
