Racepak was founded in 1985 by Spencer Eisenbarth and Ron Armstrong - both men were engineers with strong backgrounds in electrical and mechanical applications, and both had an interest in motorsports. Through an earlier joint effort aimed at obtaining data for the improvement of the Unlimited Hydroplane that Armstrong was piloting at the time, they both 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. That challenge became the initial goal that led to the formation of Racepak. In the years that have followed Eisenbarth and Armstrong have quietly guided Racepak into a strong presence in many forms of motorsports.
