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.
Hopefully the CS400 is the first of several exciting Porsches to come from PSI. The North American site for PSI is currently being developed, however, their European site makes for an entertaining browse: http://www.psi-motorsport.com/porschetuning/index.php.
