 The engine was mated to a chassis specially built by March and prepared by Alex Morales Motorsports in 1989, with Roberto Guerrero at the wheel.Guerrero only managed a best of 8th place at Detroit, before both driver and engine moved onto Patrick Racing for 1990, again with a March chassis.That season proved to be an improvement, as Guerrero finished 16th place in the points standings, with a best finish of 5th place.
