Jack Roush Performance Engineering, established by former Ford engineer Jack Roush in 1976, had been known for providing performance racing parts, vehicles and engines. In 1988, Roush pitched Ford on his first high performance Mustang variations, a 400 hp twin turbocharged beast of a machine. Roush had hoped to form a partnership with Ford which would put his Mustangs in dealer showrooms across the country. Unfortunately, Ford passed on this collaboration noting the vehicles would be too expensive to mass produce.
