My dad worked for Rupp as a mechanical engineer in R&D and was a Kart racer. Heard a lot of stories from him, mostly failure stories of engines letting go at MidOhio and Vegas. Since he passed away I've been trying to find everything I can about his career, I know there is a 100mph club plaque for Daytona somewhere. Wish I could have wrote down all the stories I heard, as well as got him to tell me more. His brother always bragged about him, but my dad never really talked about success. I still have a metal Rupp snowmobile box in my back yard that he kept with him everywhere he moved. If you have any interest in sharing stories please let me know, I would love to hear more of the era my father raced in.
