[1][2][3][4][5][6] As a result of Jack Brabham's long-standing relationship with Honda, Judd was hired by them to develop an engine for the company's return to Formula Two in association with Ron Tauranac's Ralt team.

After the demise of Formula Two at the end of the 1984 season, Judd continued to develop new engines for Honda.

It was first used on the CART circuit midway through the 1986 season, fielded by Galles Racing and driver Geoff Brabham.

Brabham scored second-place finishes in 1987 at Pocono and Road America, as well as a third at the season finale at Miami.

In 1988, Truesports with driver Bobby Rahal took over as the primary team, and the "Honda" name was dropped from the powerplant.
