PSI TAKES A SYSTEMS APPROACH TO RACING, ALL OF OUR PRODUCTS ARE DESIGNED TO "SOLVE A problem, THEY ARE SIMPLE AND DIRECT" AND "THEY ARE MADE WELL". We know that you can't race and Win if everything isn't right. In racing it's the "weak link that breaks the chain". We don't just sell superchargers, we design and build them. our idea of r&D truly revolves around research & development. we leave the mentality of "rip off and duplicate" to others.
