Bowe's last open wheeler race was in the Formula Mondial support race at the 1986 Australian Grand Prix in Adelaide. Driving a Ralt RT4 in the race (for the first time in 12 months), Bowe equalled the category lap record for the Adelaide Street Circuit set one year earlier by American driver Ross Cheever, the younger brother of Formula One driver Eddie Cheever. Bowe's time of 1:33.20 for the 3.780 km (2.362 mi) track compared to the fastest Formula One race lap of the circuit that year of 1:20.78 set by Nelson Piquet driving a turbocharged Williams-Honda.
