ABOUT THE BRAND
        Racepak LLC was founded in 1985 by Spencer Eisenbarth and Ron Armstrong, originally as Racepak and its parent company, Competition Systems, Incorporated (CSI). Both men were engineers with strong backgrounds in electrical and mechanical applications, and both had an interest in motor sports. Through an earlier joint effort aimed at obtaining data for the improvement of the Unlimited Hydroplane that Armstrong was piloting at the time, both men realized the need for onboard data acquisition equipment. Their respective backgrounds qualified them to develop such equipment, but the major task that needed to be overcome was in designing and building a data recorder that could survive in the unfriendly world of race vehicles.
