On the circuit, Pilette raced for Carlo Abarth in 1963 and 1965, and in 1967 he started racing for the Belgian VDS team. He won the European Formula 5000 Championship in 1973 with a Chevron B24, and again in 1975 with a Lola T400. He also competed in the US in Formula 5000. He also made 3 attempts at the Indy 500. He attempted to qualify for the 1977 Indianapolis 500 but failed to make the field. He drove in the CART Championship Car race at Watkins Glen International in 1981 but retired after 14 laps due to gearbox failure. It would be his only Champ Car start as he failed to qualify for the 1982 Indianapolis 500 and 1983 Indianapolis 500 and was entered in the Cleveland Grand Prix later that year but the car was driven by Herm Johnson.
