Micky Rupp was the manufacturer of go karts in Mansfield, Ohio. The engine for his monster snow mobile came from his Indy car.
You can order the latest release of the model kit on ebay.... I believe MPC is using the same box art....
Mini bikes too. "Rupp Industries was born in 1959 when Mickey Rupp began ***embling and selling go-karts from his ba*****t. Originally Rupp Manufacturing, the name Rupp Industries was adopted by 1971. In that year Rupp employed 400, with 23 engineers in the R&D department and sales in the millions. In addition to their popular go-karts, Rupp began producing minibikes and snowmobiles in the early 1960s. Mickey Rupp sold the company in 1973 when it ran into financial trouble. Although the company would continue to produce dirt bikes, minibikes and snowmobiles, they would never regain financial stability and by 1978 went bankrupt.[2]" https://en.wikipedia.org/wiki/Rupp_Industries
There was a big push in the early 70's by many of the snowmobile manufactures to set the "On Snow" land speed record. Rupp, Arctic Cat, Polaris, Ski-Doo, Alouette, and others all built custom snowmobiles just to go after the record. Blown and Injected small blocks, multi engine contraptions, and even one Turbonique powered sled all showed up in Boonville, NY to try and set a record. There was some wild stuff built. It may not have much to do with our favorite automobile era, but it is still hot rodding. https://www.snowtechmagazine.com/the-chase-for-a-snowmobile-world-speed-record-a-short-history/ https://web.archive.org/web/20181231171645/http://bos****legacy.com/
